Wear and tear
Pumps or parts of pumps are subject to wear in accordance with the
current technical standards (DIN 31051/DIN-EN 13306). This wear
may vary depending on the operating parameters (temperature,
pressure, speed, water conditions) and the installation/usage situation and may result in the failure of the above products/components,
including their electrical/electronic circuits, at different times.
Wear or wearing parts are all components subject to rotary or dynamic stress, including electronic components to which voltage is applied, including in particular:
• Gaskets (including mechanical seals), seal rings.
• Stuffing boxes.
• Bearings and shafts.
• Impellers and pump components.
• Thrust rings and wear rings.
• Wear rings / wear plates.
• Macerators.
• Condensers.
• Relays/contactors/switches.
• Electronic circuits, semiconductor components etc.
Pumps and continuous-flow machines (such as submersible mixers
and recirculation pumps) and their coated components (cataphoretic,
2K or Ceram coating) are subject to constant wear due to the abrasive
content of the fluids. For this reason the coating of these units is also
counted as a wearing part!
We do not accept any liability for faults or defects arising from natural wear and tear.

Series description Wilo-EMU TR 50-2… – TR 120-1...
Scope of delivery
Seal
Sealing is achieved through the use of a 3-chamber system (prechamber, gear chamber and sealing chamber). The large-volume prechamber and sealing chamber collect leakage from the mechanical
seal. If desired, the pre-chamber can be equipped with an external
sealing chamber electrode. The seal between the fluid chamber and
the pre-chamber, as well as between the gear chamber and sealing
chamber, is achieved by a corrosion-resistant and wear-resistant
mechanical seal made of solid silicon carbide material. The seal between the pre-chamber and gear chamber, as well as between the
sealing chamber and motor, is achieved by radial sealing rings. A seal
bushing ensures long-term corrosion-protected fit of the mechanical
seal.
Configuration
Commissioning
The unit can be used immersed in permanent operation. Surfacing
the propeller or motor is strictly prohibited. In the case of fluctuating
fluid levels, the system should switch off automatically if the degree
of water submersion drops below the minimum level.
Gear
Single-stage planetary gear with exchangeable transmissions. The
gear bearings are dimensioned so that the resulting mixing forces are
absorbed and are not transferred to the motor bearings.
Cable
The power cable enters the motor housing through a water pressuretight cable inlet with strain relief and anti-kink protection. The individual wires as well as the cable sheath are additionally sealed to keep
out fluids.

Propeller
2- or 3-bladed propeller with a nominal propeller diameter of
1200 mm to 2600 mm. Entwining-free design made possible by
backward-curved incoming flow edge.
• Propeller blades: GfK
• Propeller hub: EN-GJS-400
• Screwed connections: Stainless steel (1.4571)
• Seal bushing: Stainless steel (1.4571)
Application
• Energetically optimized mixing and circulation of activated sludges
• Generation of flow rates in circulation channels
• Further areas of application in industry
• 2-stage planetary gear for adjusting the propeller speed
• Propeller blades can be individually replaced (not for TR 212)
• Easy-to-install blades and hub
• Propeller in GfK version
• Gear shaft 1.4462
Technical data
• 2-stage planetary gear with an exchangeable 2nd planetary gear
Motor
equipped with a temperature monitor. Large-sized inclined and
grooved ball bearings ensure long service life of the motor bearings.
TRE units are equipped with the high-efficiency TE 20 motor which
meets the IE3 classification (derived from IEC 60034-30).
Sealing
Sealing is achieved through the use of a 3-chamber system (prechamber, gear chamber and sealing chamber). The large-volume prechamber and sealing chamber collect leakage from the mechanical
seal. If desired, the pre-chamber can be equipped with an external
sealing chamber electrode. The sealing between the fluid and the
pre-chamber, as well as between the gear and sealing chamber are
realized by a corrosion-resistant and wear-proof mechanical seal
made of solid silicon carbide material. The sealing between the prechamber and gear chamber as well as between the sealing chamber
and motor is realised by radial sealing rings. A seal bushing ensures
long-term corrosion-protected fit of the mechanical seal.
53
Gear
2-stage planetary gear with exchangeable transmissions. The gear
bearings are dimensioned so that the resulting mixing forces are absorbed and are not transferred to the motor bearings.
Configuration
Cable
The power cable enters the motor housing through a water pressuretight cable inlet with strain relief and bend protection. The individual
wires as well as the cable sheath are additionally sealed to keep out
fluids.
Commissioning
Options

Design
Equipment/function
Solids diffuser
The solids diffuser permanently sucks the biomass particles from the
surface of the basin and channels them back to the lower layers of
the fluid via the pipe. The angled outlet ensures the biomass particles
do not drift up or down in an undefined manner, but remain in the
fluid for a longer period, thereby supporting the biological process.
This circuit ensures the biomass particles are only at the surface of
the fluid for a limited time and that they remain active for the treatment process for a considerably longer period.

The solids diffuser consists of a pipe with angled outlet, a submersible motor and a propeller.
The pipe is used here for channelling and direct entry of particles into
the fluid. The angle of the outlet can be adjusted vertically and horizontally according to the relevant conditions.
The motor is secured centrally in the pipe. A dry motor with IE0 or IE3
classification (in accordance with IEC 60034-30) is used here. The
heat from the motor is transferred directly to the surrounding fluid
via the motor housing. The winding is equipped with a temperature
monitor. The power cable is a type NSSHÖU cable for heavy mechanical loads. The power supply cable enters the motor housing through
a water pressure-tight cable inlet with strain relief and anti-kink protection. The individual wires as well as the cable sheath are additionally sealed to keep out fluids.
The propeller is driven by the motor and features a specially optimised geometry for safe transport of the particles.
Options
• Winding monitoring with PTC sensors
• Ex-rated in accordance with ATEX and FM
Solids diffuser
Series description Wilo-Sevio ACT
Scope of delivery
• Solids diffuser
Configuration
In order to ensure optimum entry of the biomass particles, a separate
configuration must be introduced for each application. Install the
units precisely in accordance with the specifications of the supplied
configuration.
In the case of heavily fluctuating fluid levels we recommend using the
scum skimmer with telescopic pipe. By using this variant you can
adapt the scum skimmer to the altered operating conditions and ensure an optimum result.
Commissioning
The submersible motor must be surrounded by the fluid during operation. The motor must be prevented from emerging from the fluid. In
the case of fluctuating fluid levels, the system should switch off automatically if the degree of water submersion drops below the minimum level.

Description/design
The aeration system is composed of one or more groups of aerator.
An aerator group forms the basic unit here and consists of several
components (see Fig. 1):
• Air distributor with connecting flange for the inlet pipe (downspout)
• Base support for air distributor
• Aerator pipe with pre-assembled disc aerators
• Disc aerator
• Base support for aerator pipe
• Drainage connection
• Pipe couplings for connecting the individual components
steel pipework
• Max. air temperature in the system/disc aerator: 100 °C
90
Ventilation systems
Base support
The base supports are used to attach the complete pipework to the
bottom of the basin. These also enable levelling of the aerator
groups. Two different base supports are available:
• a stainless steel support for attaching the air distributor
• a PVC support for attaching the aerator pipes and the drainage connection
Disc aerator
The supplied air is channelled into the fluid in the form of fine bubbles. The air is distributed over the entire diaphragm surface here and
discharged through the perforated diaphragm. The disc aerator consists of the following components (see Fig. 2):
• Screw ring: for attachment of the diaphragm to the diaphragm
mount.
• Separation ring: prevents the diaphragm from sticking to the screw
ring. This ensures simple replacement of the diaphragm even after
many years of operation.
• Diaphragm: with full-surface perforation for optimum aeration.
• Diaphragm mount: with support function for the diaphragm.
• Non-return valve: protects the aeration system from the penetration
of fluid in the event of a defective diaphragm.
• Aerator housing: with integrated anti-twist protection
• O-ring: for sealing the disc aerator on the aerator pipe
• Slide closure: for simple installation and dismantling of the disc aerator
Pipework
The pipework is supplied in prefabricated, easy to use components:
• Air distributor in diameters of 90 mm, 160 mm and 200 mm, manufactured from PVC with central or side flange connection DN 80 to
DN 200 for the inlet pipe. Larger diameters are available in stainless
steel with flange connections DN 125 to DN 350.
• PVC aerator pipes with 90 mm outer diameter or stainless steel aerator pipes with 88.9 mm outer diameter, with pre-assembled disc aerator
• Drainage connection as a terminal connection for all aerator pipes
with connection for the drainage line. This can be used to drain the
condensate which can form during ventilation.
• PVC pipe coupling with rubber seal as a plug connection for combining the individual components. The pipe couplings for attaching the
aerator pipes to the air distributor are also equipped with a stainless
steel taper lock ring.

Commissioning
Configuration
The basin must be thoroughly cleaned and a clear water test performed prior to commissioning.
We recommend storage in a ventilated room with a temperature that
is maintained between 10 °C and 25 °C. The temperature must not
exceed +50 °C. New disc aerators may be stored for a maximum period of 3 months. If they are stored for longer than 3 months, there is a
risk of the diaphragm becoming porous and permeable.
Thorough cleaning
Numerous contaminants may accumulate in the basin during installation. These contaminants can adversely affect the aeration process or
damage the disc aerator. Therefore, clean the entire basin with clear
water and remove any contaminants. Coarse contaminants and debris are to be disposed of by hand. The water jet should not impact
directly against the diaphragm, as this can result in damage.
Clear water test
By conducting a clear water test it can be ensured that all of the components are tight and that the aerator groups are working properly.
This test must be performed with clear and clean water. Personnel
must drain the aerator groups in the basin during the test. A visual inspection from the corners or outside the basin is not permitted.
The fluid temperature must be between +5 °C and 30 °C. The manufacturer must be consulted if use in fluids with higher temperatures is
intended. In addition, the surrounding fluid must be free of any sharp
objects. It is recommended to clean the fluid beforehand with a filter.
The supplied air must be free of oil, dust and solvents. Dust filters
must comply with filter class EU4 according to DIN 24185 (degree of
separation >90 %). All filters and insulating materials used should not
consist of fibreglass, mineral fibres or other fibrous materials. Rotary
slide valves with graphite discs must be equipped with an air filter on
the pressure side. These materials can clog or damage the diaphragms.
Material to be provided by the customer:
• Inlet pipe for air supply
• Fan or compressor (also available on request)
• Drainage line with stop valve
92
Ventilation systems
Equipment/function
A fan or compressor pumps air into the air distributor via the inlet
pipe. The air distributor distributes the air evenly to the individual
aerator pipes and the disc aerators. The disc aerators distribute the air
over the entire diaphragm surface and channel it into the fluid in the
form of fine bubbles.
Options
The use of submersible mixers for flow generation in the treatment
basin ensures an increased exchange of materials, as the residence
time of the rising air bubbles and the shearing rate at the contact surfaces of the aeration elements are positively influenced. In addition,
the submersible mixer also prevents settlement of the activated
sludge/sewage mixture when aeration is switched off.
Therefore, we recommend a combination of the aeration system and
submersible mixers in order to achieve an optimum exchange of materials in the purification process and to reduce energy consumption
and operating costs as much as possible.

Description/design
Propeller
2-blade steel propeller with a nominal propeller diameter of 500 mm.
Entwining-free design made possible by backward-curved incoming
flow edge.
Motor and gear
Wilo T-series submersible motor with standard connection and single-stage planetary gear for simple and efficient adjustment of the
motor power and propeller speed. The motor heat is given off directly
to the fluid via the housing. The winding is equipped with a temperature monitor. Large-sized inclined and grooved ball bearings ensure
long service life of the motor bearings. The gear bearings are dimensioned so that the resulting mixing forces are absorbed and are not
transferred to the motor bearings.
Technical data
• Mains connection: 3~400 V, 50 Hz,
• Gear: Single-stage planetary gear
Sealing
Sealing is achieved through the use of a 3-chamber system: prechamber, gear chamber and sealing chamber.
• The large-volume pre-chamber absorbs any leakage occurring on the
fluid side and is sealed on the fluid side with a mechanical seal. A seal
bushing ensures long-term corrosion-protected fit of the mechanical
95
Industrial process
seal. The pre-chamber is equipped with an external angular moisture
probe as standard.
• The gear chamber contains the planetary gear and is sealed from the
pre-chamber with a rotary shaft seal and from the sealing chamber
with a mechanical seal.
• The sealing chamber absorbs any leakage occurring through the mechanical seal of the gear chamber and is sealed on the motor side
with a rotary shaft seal.
The pre-chamber and gear chamber are filled with a CLP gear oil,
while the sealing chamber is filled with a potentially biodegradable
white oil.
Cable
The power cable is a type TGSH-J cable, which is suitable for use in
potentially explosive areas with fluid temperatures up to max. 90°C.
The power cable enters the motor housing via a cable inlet that has
been specifically designed for this purpose, complete with strain relief and anti-kink protection. The cable is provided with a protective
sleeve for added abrasion protection. The individual wires and the cable sheath are sealed to prevent fluid from entering via a defective
cable.
Options
These submersible mixers are marketed as defined standard versions.
Any desired adjustments must therefore be agreed with the manufacturer.
Configuration
In order to ensure an optimum result for flow generation, a separate
configuration must be introduced for each application. Install the
units precisely in accordance with the specifications of the supplied
configuration.
To use the submersible mixers with a lowering device, the appropriate guide carriage must be ordered as an accessory. The carriage is
available for lowering devices with a 50, 80 or 100 mm guide pipe.
Commissioning
The submersible mixer must be immersed when operated. Surfacing
the propeller is strictly prohibited. In the case of fluctuating fluid levels, the system should switch off automatically if the degree of water
submersion drops below the minimum level. The power supply cable
and any electrode cables are to be installed in such a way that they
cannot be drawn into the propeller!
Accessories
• Guide carriage for use with lowering devices
• Lowering devices
• Terminal stop
Scope of delivery
• Submersible mixer with assembled propeller

Hydraulics
The angle of the propeller/impeller blades can be adjusted by hand.
This makes it possible to adapt the unit to use in different conditions.
Motor
Dry motors (T motors) give off their heat directly to the surrounding
fluid via the housing components and can be used in immersed state
for permanent operation.
A sealing chamber protects the motor from fluid ingress. It can be accessed from the outside and can be monitored with an optional sealing chamber electrode.
All filling fluids used are potentially biodegradable and environmentally safe.
The cable inlet of the T motors is longitudinally watertight. Cable
lengths can be individually configured.
Sealing
Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:
• Version G: Two independently operating mechanical seals
• Version K: Block seal cartridge with two independently operating mechanical seals

Series description Wilo-EMU KPR
Options
Accessories
• Internal or external sealing chamber control
• Monitoring units for leakage and bearing temperature
• Ceram coating C0, C1
• Ex-rated according to ATEX or FM
Scope of delivery
• Switchgears, relays and plugs
Commissioning
Operation with surfaced motor:
Dry motors (T motors) can be surfaced only if there is an operating
mode for surfaced operation.
Dry-running protection system:
The hydraulics housing must always be immersed to prevent air from
being drawn in. In the case of fluctuating fluid levels, the system
should switch off automatically once the minimum water submersion
is reached.

Equipment/function
• Submersible sewage pump with self-cooling motor
• Jet cleaner with jet pipe, air suction pipe and injector nozzle
Description/design
Jet cleaner comprising jet pipe, air suction pipe, injector nozzle and
submersible sewage pump for stationary wet well installation.
Application
• With a submersible sewage pump
• This can be operated even during the filling phase
• It can be installed in new and existing basins
• The rainwater that is present is used for cleaning
• Oxygen is injected via a separate suction pipe during operation
• The length of the jet pipe and air suction pipe can be adjusted individually
• For agitating the organic and inorganic materials in rainwater
• Oxygen injection reduces the build-up of slime when water is standing for long period in the rainwater basin
Technical data
Jet cleaner:
• Circulation output:100…200 m³
• max. basin size: 15 m (round), 10x20 m (rectangular)
• Pressure connection:DN100 or DN150
Sewage pump:
Pump
Submersible sewage pump as submersible monobloc unit with selfcooling motor. The pressure-side outlet is connected directly to the
jet pipe. The maximum possible dry matter is 8 %. Single-channel
impellers are used as the impeller shape. The use of self-cooling motors allows the units to be operated continuously in either submerged
and dry condition.
Dewatering
• For cleaning the rain spillway basin even during the emptying phase.
• For reducing the build-up of slime by injecting air
• For agitating the organic and inorganic materials
Jet cleaner
The submersible sewage pump sucks any rainwater present out of
the drain channel in the basin, and pumps it through the injector nozzle via the jet pipe back into the basin.
According to the principle of the water jet pump, at the same time
oxygen is sucked into the rainwater via the air suction pipe during
this operation. The exiting air/water drive jet is under high pressure
and reaches far into the basin. This causes a turbulent flow, which, in
turn, prevents solids from depositing.
So as to ensure a stable process, the jet cleaner is equipped with submersible units with self-cooling motors. This means the jet cleaner
can be installed directly in the basin, and operated during the filling of
the basin until the rain spillway basin has been emptied. This agitates
the solids and dirt so that they form a suspension and are carried out
of the basin together with the rainwater.
• Surfaced operating mode: S1
• Max. fluid temperature: 3 - 40 °C

Description/design
Submersible sewage pump with mechanical stirring apparatus as
submersible monobloc unit for stationary and portable wet well installation.
Hydraulics
The outlet on the pressure side is designed as horizontal flange connection. The maximum possible dry matter content is 8%, depending
on the hydraulics and impeller type.
Vortex impellers are used exclusively as the impeller shape. A mechanical stirring apparatus is mounted to these as an axial extension
of the motor shaft. The mixer head is made of Abrasite chilled cast
iron.
Motor
Dry motors (T motors) give off their heat directly to the surrounding
fluid via the housing components and can be used in immersed state
for permanent operation.
179
Series description Wilo-EMU FA...WR
The oil-filled motors (FK motors) and self-cooling dry motors (FKT,
HC motors) give off their heat to the pumped fluid via a built-in heat
exchanger. As a result, these motors are suitable for permanent operation either in immersed or non-immersed state.
All motors have a sealing chamber that protects the motor from fluid
ingress. It can be accessed from the outside and can be monitored
with an optional sealing chamber electrode.
All filling fluids used are potentially biodegradable and environmentally safe.
The cable inlet on T, HC and FKT motors is longitudinally watertight.
Up to motor size 17, cable lengths are available in fixed lengths
measured in 10 m intervals. Starting from motor size 20, the cable
length can be individually configured.
Sealing
Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:
• Version H: Mechanical seal for the fluid side, rotary shaft seal for the
motor side
• Version G: Two independently operating mechanical seals
• Version K: Block seal cartridge with two independently operating mechanical seals
Options
• Ceram coating C0, C1, C2, C3
• Ex-rated according to ATEX or FM
Scope of delivery
• Submersible sewage pump with mechanical stirring apparatus
• Up to motor size 17, cable lengths are available in fixed lengths
measured in 10 m intervals; starting from motor size 20, per customer
request
Accessories
• Suspension unit or pump base
• Various pressure outlets and Storz couplings
• Chains
• Switchgears, relays and plugs
Commissioning
Operation with surfaced motor:
The surfacing of self-cooling motors (FK, FKT, HC motors) is permitted.
Dry motors (T motors) can be surfaced only if there is an operating
mode for surfaced operation.
Dry-running protection system:
The hydraulics housing must always be immersed to prevent air from
being drawn in. In the case of fluctuating fluid levels, the system
should switch off automatically once the minimum water submersion
is reached.
• Internal or external sealing chamber control
• Monitoring units for leakage and bearing temperature
• Special materials, e.g. Abrasite

The auxiliary hoisting gears have a bearing capacity between 125 and 500 kg and are used as
simple-to-use lifting gear for raising and lowering of submersible mixers or pumps. Smaller
submersible mixers up to size TR 40 can also be used to operate the units at different heights.
The auxiliary hoisting gear consists of a separate holding sleeve for the wall or floor fixation
and the auxiliary hoisting gear with manual winch. The height of the manual winch is infinitely
variable starting from the 250 kg version. Furthermore the hoisting gears (version ZT) are also
available with 2 or 3 booms with a jib length of up to 3.2 metres.
Additionally, another cable bollard is available upon which the bearing cable (if it can not remain in the hoisting gear) can be wound up and secured. This makes it possible for one auxiliary hoisting gear to be used for several units.
The auxiliary hoisting gears as well as the holding sleeve are made of galvanised steel materials, A2 (1.4301) and A4 steel (1.4571); the cable bollard is make of A2 and A4 steel. The rope
pulley and the sliding elements in the holding sleeve are of sewage-resistant plastic. The manual winch can be made of either aluminium or stainless steel. All auxiliary hoisting gears have
been tested and certified by the LGA and have the GS quality mark.

Catch hook and catch device
Firstly, in order to use an auxiliary hoisting gear for more than one unit, the bearer cable must
always be removed and secured. Secondly, the bearer cable is always exposed to enormous
traction forces within the fluid and is therefore subject to increased wear.
When a catch hook or catch device is used, the unit can be lowered as usual. As soon as the
unit is on the support, the catch device hooks or the catch device is released and can be pulled
out of the fluid again. In this way, the bearer cable does not have to be removed and secured
and is not exposed to the fluid.
The catch hook is swivelled back and forth with the bearer cable until it hooks into the unit's
handle. Due to the operating principle of the catch hook, it is only suitable for use in depths of
not more than 3 metres.
The catch device is a further development of the normal catch hook and consists of a catch
hook and a guide element. While one has to know exactly where the catch clip is positioned
when using the catch hook, the guild element ensures the correct distance. This is simply put
onto the guide pipe of the lowering device and lowered onto this until the catch hook engages
the guide bracket. In this way, the catch device is suitable for use in greater depths.

Lowering devices
Different lowering devices are available for the simple installation of the submersible mixers
and recirculation pumps. These fixtures are flexible guidance systems for wall and floor fixation for simple raising and lowering of the units. Furthermore, the lowering device absorbs the
mixing forces which arise and transfer them to the structure. A high resisting torque in the
guide pipes, plastic linings in the sliding carriage and large-area rubberised supports guarantee
high stability and long service life.
The lowering devices of type AVU… are designed for use with submersible mixers of the series
TR 14 … TR 90-2. These are fixtures for wall and floor fixation. The floor fixation is done by a
ball joint made of plastic. This permits even slight unevenness on the floor to be compensated
for during installation. For optimum mixing results during this, the mixer can be swivelled horizontally. In connection with auxiliary hoisting gear, mixers up to the size TR 40 can also be operated in different heights.
The lowering devices of type AVM… are designed for use with submersible mixers of the series
TR 216 … TR 326. These are fixed stand systems for free positioning at the base of the basin.
These permit the mixers to be placed for optimum mixing results. If the stand is pre-mounted
to a concrete slab, this can also be installed later in an already filled basin.
The lowering devices of type AVR… are designed for use with recirculation pumps. These are
fixed stand systems for wall-mounted installation. Recirculation pumps can be directly flanged
on the discharge pipe using these.. Due to the different variants of this lowering device, corner
installations are also possible.
The material of the lowering device depends on the sewage constituents, such as the chloride
content. The materials common in water treatment system construction, A2-steel (1.4301)
and A4-steel (1.4571), can be processed and delivered. Standard lengths up to 6 metres are
available. Custom lengths available on request.
The lowering devices are installed using building-approved anchor bolts directly on the structure. In the case of fixation to steel construction parts, installation is done using rustproof
screwed connections. Installation is complete without welding work.

Additional cable anchoring
Normally, the power lines are fastened to the traction rope and are installed upwards.
To prevent damage to the cable at the edge of the basin, we recommend a rope anchoring
with a separate holder at the edge of the basin. This can prevent cable abrasion and cable
breaks.
In addition, high flow rates in the fluid can cause strong traction forces to act on the traction
rope and the power cables and lead to increased wear. To relieve both, we recommend an additional rope anchoring made of nylon can be used. The traction forces are then absorbed by
the polyamide rope.
Furthermore, rope anchoring is recommended when using a catch hook or catch device, since
here the traction rope does not remain in the basin.

Structure of a water treatment system
A water treatment system is for cleaning sewage, which has been
collected from the sewer system and fed to it.
To clean the undesirable sewage contents, mechanical, biological and
chemical methods are used. Modern water treatment systems are designed accordingly as multistage systems. The first water treatment
system on the European continent was put into operation in 1882
Frankfurt am Main.
System components
Rain relief
When feeding sewage to the water treatment system, two sewer
systems are to be distinguished, the mixing system and the separating system.
In the case of the mixing system, the rainwater and drainage and
sewage are fed into a common channel of the wastewater treatment
system. Here, the sewage network usually has to be relieved by a rain
overflow or a rain spillway basin so that the water treatment system
isn't hydraulically overloaded. This can be done using a rain spillway
basin (RSB), either already in the sewage network or later on in the
water treatment system. If such facilities are not available, the water
treatment system must be provided with the corresponding reserve
capacity.
The incoming rainwater is particularly severely contaminated after
long dry periods. There are deposits due to the long dwell times in the
RSB. These deposits can lead to major odour problems in an anaerobic
environment. This is where Wilo jet cleaners are used. They are
equipped with Wilo submersible pumps of the Wilo-EMU type and
can therefore also be operated in an immersed state. The jet cleaners
add oxygen to the fluid and prevent solids from depositing.
In the case of the separating system, the sewage is fed to a separate
pipe of the water treatment system while the rainwater is pumped
through a separate pipe, if necessary, after cleaning in a rainwater
treatment basin, directly to surface water.
Rake
In the raking system, the sewage is pumped through a rake or screen
drum. The coarse contaminants, such as monthly hygiene articles,
condoms, toilet paper, cotton swabs, stones or even leaves and dead
animals are caught in the rake. The more narrow the passage for the
sewage, the less coarse material remains in the sewage after the rake,
which has a positive effect on the wear of the machines in the subsequent cleaning stages.
A distinction is made between fine rakes with a few millimetres gap
width and coarse rakes with a few centimetres. The material caught
in the rake is mechanically washed to remove the faecal matter. The
water is removed with a rake material press (to save weight) and then
the material is burned, composted (fertiliser) or is brought to a landfill.
Grit chamber
A grit chamber is a sedimentation tank with a defined dwell time. Its
task is to remove coarse, depositable contaminants from the sewage,
such as sand, stones or pieces of glass. These substances can easily
lead to system malfunctions (wear, clogging). The purpose is to separate inorganic particulate substances from organic constituents,
which are eliminated in further cleaning stages and which contribute
to gas production when the sludge decays.
Possible designs include:
• Long grit chamber
• Ventilated long grit chamber, in which both grease and oil on the surface are separated
Another option for suspending potential deposits in the RSB is the
application of our directly driven Wilo Miniprop submersible mixers.
These can be fastened directly to the basin's base or wall and generate sufficient turbulence to counteract the depositing of solids.
• Round grit chamber
• Deep grit chamber
There is a ventilation unit installed on the basin's base, through which
turbulence is generated. Due to the air that is blown in, the density of
the sewage is reduced. Due to these effects, the heavy mineral components (mostly sand) settle on the base of the basin.
In modern systems, the collected sand is washed after removing it
from the grit chamber, i.e. it is freed of organic constituents in order
to improve drainage and make subsequent recycling possible (for example for road construction).
220
Consulting guide
When emptying the grit chamber, high demands are placed on the
wear resistance of the used pumps. Deposits (especially sand) must
be stirred up and pumped out. Wilo offers grit collector pumps for
this. They are Wilo-EMU FA pumps with a mechanical stirring apparatus (Wilo-EMU FA…WR). With these, the sand is only stirred up in the
area of the pump inlet. Solid deposits are loosened up and can be
pumped. Due to the narrowly limited flow zone, the settling of sand is
not disturbed. The smooth pipe cylinder can usually be rinsed free of
long fibrous substances on its own. Since the stirring apparatus is
subject to a high degree of wear, it is made of the chilled cast iron
material Abrasite. The pumps are directly fastened to the chamber
bridge and submerged in the fluid.
As an example, the activated sludge method is described below. The
majority of municipal water treatment systems in central Europe are
operated according to this method.
Activated sludge tank
With the sludge activation method, the organic sewage constituents
are oxidatively degraded to CO2 and H2O in activated sludge tanks by
aerating the suspension made up of sewage and activated sludge. At
the same time, the nitrogen compounds are oxidised to form nitrate,
which is the first step for the elimination of nitrogen.
The second step, denitrification, takes place under anoxic conditions
(absence of dissolved oxygen). For this reason, it must take place at a
different time/place than nitrification.
The activated sludge method is run continuously. This means that
sewage and activated sludge are continuously fed into the activated
sludge tank. At the same time, the suspension from the sewage and
activated sludge takes place to the same degree. By adding flocculating agents, the nutrient phosphorus can also be removed by means of
chemical reactions.
In the activated sludge tank, Wilo Maxiprop/Megaprop submersible
mixers are used to ensure a sufficient mixing and flow rate during the
non-aerated phases (denitrification).
Primary clarifier
The hydraulic dwell time in the primary clarifier is significantly longer
than in the grit chamber. For this reason, the grain size of the particles eliminated here by means of sedimentation is much smaller than
in the grit chamber. Undissolved substances (faecal matter, paper,
etc.) are deposited or float on the surface. About 30 % of the organic
matter can be removed in this manner. Primary sludge is formed,
which is transferred to what are called pre-thickeners in most water
treatment systems. It is thickened there, together with the surplus
sludge from the sludge activation system: The sludge is deposited
and the surplus water (cloudy water) is removed to establish a higher
dry substance content. The cloudy water is fed back to the cleaning
circuit of the water treatment system. The thickened sludge is
pumped into the digestion tank for further anaerobic treatment.
In the case of modern systems with nitrogen elimination, this part of
the system can be omitted or often has small dimensions. This is justified by the necessary presence of organic substances in sewage for
supporting denitrification.
This system component is not used for water treatment systems with
simultaneous, aerobic sludge stabilisation in the biological stage either, otherwise non-stabilised primary sludge would continue to accumulate.
Biological stage
In this process stage, the undesirable sewage constituents are biologically degraded by microorganisms. This is called activated sludge.
For this purpose, the sewage is oxygenated. Numerous procedures
have been developed: the activated sludge method, the percolating
filter method, the fixed-bed reactor method.
Secondary clarifier
The secondary clarifier forms a process unit with the activated sludge
tank. The activated sludge is separated there from the sewage by
sedimentation. Part of the sludge is fed back into the activated
sludge tank (return sludge) in order to keep the concentration of microorganisms in the activated sludge tank constant.
The surplus (growth of biomass, surplus sludge) is fed away to the
pre-thickener for further treatment, usually together with the sludge
of the primary clarifier.
Wilo recirculation pumps ensure that the sludge is fed back. These
are able to pump a high volume flow over low heights.
221
Consulting guide
The activated sludge must have good settling properties. If this isn't
the case, for example due to massive growth of filamentary microorganisms, the activated sludge drifts out of the secondary clarifier into
the following body of water. This phenomenon is called bulking and
floating sludge and pollutes the receiving water.
Digestion tank
The growth of biomass created by the degradation of sewage constituents is eliminated as sewage sludge, but usually degraded in socalled digestion tanks under anaerobic conditions by other microorganisms to form digested sludge and combustible digester gas
(mostly a mixture of methane and carbon dioxide). The processes are
similar to those in a biogas system.
The digester gas (in cleaned form) is frequently used in gas motors (or
even in combined heat and power plants) for covering the current
(and heat) requirements of the plant.
The digested sludge is then fed to a post-thickener. There it settles
and is thus thickened which further reduces the volume and water
content. The cloudy water is specifically removed with a special
height-adjustable removal mechanism. Wilo-Uniprop submersible
mixers are used there for homogenising the thickened sludge.
The formed sludge can be used in agriculture as an organic fertiliser if
it's free of toxic substances and poisons. Otherwise, more water is removed in chamber filter presses or centrifuges and it is burned in
waste incineration plants or is disposed of in other ways.
Treatment processes
1st stage: The first treatment stage usually consists of mechanical
processes. Roughly 20 - 30 % of the solid (undissolved) floating and
suspended matter is removed. In advanced wastewater treatment
and in industrial water management, adsorption, filtration and stripping are used.
2nd stage: Biological processes are used in the second treatment
stage of municipal wastewater treatment systems and for degrading
organically highly contaminated sewage in aerobic and anaerobic
wastewater treatment. They use microbiological degrading processes. Here, the degradable organic sewage constituents are mineralised
as completely as possible, which means, in aerobic wastewater treatment, the sewage is degraded down to the inorganic end products
water, carbon dioxide, nitrate, phosphate and sulphate.
In anaerobic wastewater treatment, they are converted to organic
acids, methane and carbon dioxide. Usually, the carbon compounds
are removed from the sewage this way. Also, nitrogen and ammonium in organic compounds are removed by means of bacterial nitrification and denitrification. Phosphorus is also being increasingly eliminated using bacteria in medium-sized and large water treatment
systems.
3rd stage: Chemical processes: Abiotic/chemical processes make use
of chemical reactions, such as oxidation and precipitation without
the participation of microorganisms. In municipal wastewater treatment, they mostly serve to remove phosphorus using precipitation
reactions. This process is very important for avoiding the eutrophication of the receiving water. In addition, abiotic/chemical methods are
used for precipitation in industrial water management and for advanced wastewater treatment (for example flocculation/precipitation/filtration).

the sewage constituents to be removed by means of biological processes
(respiration, biomass growth) into forms which can be removed from the
sewage by sedimentation or stripping (gaseous expulsion) and also are as

Load parameters
Degree of contamination
The load of water treatment systems is determined according to the
total number of inhabitants and population equivalents (PT). This is
the sum of the actual inhabitants (population, P) and the population
equivalent (PE). The population equivalent is the agreed quantity of
sewage emissions assumed for one "standard inhabitant".
For commercial, industrial and agricultural production, the loads are
specified with reference to the production amounts (e.g. 10 PT
BOD5 per hectares vineyard acreage). It is to be observed, however,
that the ratios between the individual parameters can vary. Sewage
can have a higher concentration (less sewage volume for the same
amount of contamination), or it can be rich in organic carbon compounds and have fewer nutrients.
The content of biodegradable substances is quantified with the sum
parameter Biochemical Oxygen Demand, or BOD for short. As a rule, it
is measured in milligrams of the biochemical oxygen consumption
within 5 days under standard conditions of 20 °C and is referred to as
BOD5. For biotic degradation, a nutrient ratio of BOD5:N:P of about
100:5:1 is favourable in order to supply the microorganisms with a
sufficient amount of nitrogen and phosphorus. This is based on the
assumption that about 50 % of the degraded organic substances are
used for biomass growth and that the biomass consists of about 10
% nitrogen and about 2 % phosphorus.
BOD5
With the BOD5 value, i.e. the biochemical oxygen demand during a
measurement time of 5 days under standard conditions, the oxygen
demand is measured which arises due to the oxidation of organic
substances by aerobic microorganisms. It belongs to what are called
sum parameters, since the degradation of single compounds cannot
be determined with it.
60 g per inhabitant and day are assumed as the normal BOD5 value.
About 20 g can be removed by means of sedimentation during the
primary treatment.
Chemical oxygen demand
The chemical oxygen demand, or COD for short, is also among the
sum parameters, since no individual compounds can be quantified
with it. It is determined by means of oxidation of the sewage contents by potassium chromate and measures the oxygen demand for
oxidising a majority of organic substances. If there are also oxidisable
inorganic compounds, such as sulphites, in the sewage, these are also
registered as COD.
This parameter is also used for balancing the system.
For the COD, a value of 120 g per inhabitant and day is assumed.
The total number of inhabitants and population equivalents, or PT for
short, is equivalent to the following values:
Amount of drainage and sewage
Formerly, a wastewater value of 150 to 200 litres per inhabitant and
day was assumed as the load for a water treatment system with sewage. The wastewater value is roughly equivalent to the water consumption. For new planning or advance planning, the location-specific water consumption is determined and an estimation is
attempted to be made for the future. Normally, wastewater volumes
of around 130 litres per inhabitant and day are assumed.
This value takes the usual values for leak-tight sewage networks in
Central Europe into account. For dimensioning the water treatment
system, however, usually an additional amount is taken into account
for external water (leaky channels, feed from drainage, etc.). This can
amount to up to 100 % of the wastewater value. The volume of external water refers to the connected sealed surface and should not be
more than 0.15 l/(s*hectare).
Nitrogen
In untreated sewage, nitrogen exists mainly in the form of organic
compounds (e.g. in proteins, nucleic acids, urea) and in the form of
ammonium ions (NH4+) as well as in small amounts also in the form of
nitrate (NO3-) and nitrite ions (NO2-).
About 10 to 12 g per inhabitant and day are applied here.
Phosphorus
Phosphorus exists organically as phosphate group and as free phosphate ions.
About 1.8 g per inhabitant and day are applied here.
In the case of mixed sewer systems (rainwater and wastewater in one
channel), the corresponding additional amounts for processing the
rainwater are to be taken into account, which are usually assumed to
be 100 % of the daily peak value during dry weather.
For the hydraulic calculation (number and size of the pumps) of the
water treatment system, the daily load curve is also significant. For
dimensioning therefore, the average daily sewage amount is not to
be divided by 24 hours, but instead by a smaller value (10 to 14) for
the maximum hourly value.

Cost and energy efficiency of Wilo submersible mixers
The right choice
For the operator of water treatment systems, it is not easy to make a
decision for the most economical mixing system. The least expensive
investment price should not be the decisive factor under any circumstances. Economical mixers should be compared taking all relevant
influencing factors into account. This only makes sense, however,
when all factors involved in the mixing process have been considered.
These include:
• Investment costs
• Installation and commissioning costs
• Energy and operating costs
• Maintenance and repair costs
• Operating failure costs
• Disposal costs
Only once the above-listed influencing factors have been expressed
in euros it is possible to make an objective mixer comparison.

We would like to prove our performance to you. That is Pumpen Intelligenz.
*in accordance with DIN ISO 21630
Energy costs
Since many mixer applications require permanent operation, the energy costs have a considerable influence. The decisive parameters of
submersible mixers are the thrust (F*) and the consumed electric
power at the duty point (P1.1*).
This allows important power parameters to be determined.
• Specif. thrust output [N/kW] = thrust [F] / power [P1.1]
This parameter can be used to compare the energy efficiency of different products.
• Specif. power density = power [P1.1tot] / tank volume
This parameter is used to compare different mixer designs and provides information on the energy costs to be expected.
Cost calculation
A small calculation example shows that considerable cost savings are
possible with a mixer design optimised in terms of energy.
Tank volume: 2950 m3
Mixer selection:
• According to investment costs: 3.63 W/m3 (specif. power density)
• Optimised according to operating costs: 1.7 W/m3 (specif. power
density)
The optimisation according to operating costs brings an advantage of
1.93 W/m3, which corresponds to a savings for this tank of
approx. 5700 W.
At an annual operating time of 8760 hours and a kilowatt price of EUR
0.15, that means savings of EUR 7480 EUR per basin per year.
These savings are possible by using highly efficient submersible mixers from Wilo.

Ceram coating
Modern corrosion and abrasion protection
Units that come into contact with the fluid are subject both to highly
corrosive as well as abrasive influences. For this, Wilo offers its Ceram
coating. This provides reliable protection against this type of stress.
Normal heavy corrosion protection methods, such as zinc dust priming with three coats of tar epoxy resin are called onion layer models.
The advantage of zinc dust priming is that the zinc dust sacrifices and
the zinc carbonate can seal microscopic cracks. This is referred to as
the self-healing effect of the coating. The disadvantage is that the
wet adhesion of this zinc dust priming isn't very high. Because of the
onion layer model of conventional solvent-containing coatings, the
adhesive force depends on the quality of the individual layers.
Ceram coatings are available in four different quality levels. These are
distinguished in terms of their resistance to abrasive corrosion. While
corrosion resistance is very good for all four quality levels, resistance
to abrasion increases the higher the ordinal number (C0 = low protection from abrasion; C3 = very good protection from abrasion) of
the coating, since coarser aluminium particles are processed. The individual layers get thicker and the mixture of large, medium-sized
and small aluminium oxide particles is such that even in the case of
abrasion with fine sand, the coatings are very stable.
• Ceram C0: The coating is applied using the airless method in one layer of 0.4 mm.
• Ceram C1: The coating is applied with a paintbrush and may consist
of up to three layers. The layer thickness is 1.5 mm.
The Ceram coating, on the other hand, is based on the diamond model. It unifies the positive properties of two materials by combining
aluminium oxide particles in one polymer matrix. The aluminium oxide particles are enclosed in the matrix. Thus, there are no predetermined breaking points and the adhesion is very high, e.g. in the case
of Ceram C0 15 N/mm2. Since Ceram is solvent-free, these coatings
can be applied with one layer.
• Ceram C2: The coating is applied with a spatula. The layer thickness is
1.5 mm and consists of one coat.
• Ceram C3: The coating is applied with a spatula. The layer thickness is
3 mm and consists of one coat. For tight gaps/clearance, a mechanical process is necessary.
For use in special fluids, the individual Ceram qualities can be combined with one another, e.g. C2 + C1.

Ceram coating
The Ceram coating is also very well suited for use in maritime environments. For its Ceram C0 coating, Wilo grants a guarantee of 5
years for use in seawater. The prerequisite is that the coating is intact
Increase efficiency, reduce costs
Since water is being used more and more economically, the proportion of contaminants is increasing relative to the amount of water.
This means that the concentration of corrosive and abrasive constituents is higher.
Sewage units are always exposed to this aggressive fluid. Corrosion
and abrasion affect the surfaces and material structures of the units,
sometimes with considerable impairments to the material, and thus
also the performance.
This significantly reduces the hydraulic efficiency. This results in the
units having an increased current consumption. On the other hand,
the pumps no longer work at their optimum, the radial forces increase, there is more stress on the bearings and mechanical seals, and
the service life of the machines is reduced.
When standard materials are used, such as grey cast iron, under high
stress, it may be necessary to exchange the components already after
500 hours of operation. Ceram coatings allow the service life to be
increased by a factor of 4, and this at the same high efficiency, which
means minimum energy costs.
If one takes the overall costs over the entire service life of the pump
into account, the investment costs for a unit coated with Ceram are
less than 10%, and thus negligible. On the other hand, there is a high
savings potential due to the fact that fewer repairs are required, resulting in a significant reduction of system downtimes. The amortisation is then usually quickly reached due to the higher efficiency.
Use of the various Ceram qualities
• Ceram C0 is used for the complete outer and inner coating. It's ideally
suited for corrosion protection.
• Ceram C1 is used for the inner coating of pump components. The
main field of application is the coating of the impeller and the suction
port .
• Ceram C2 and C3 are used for the inner coating of pump components.
The main field of application is the coating of the pump housing.
In order to guarantee protection even in especially aggressive and
corrosive fluids, the Ceram types are combined with each other, e.g.
C2 + C1 or C3 + C1.

Ceram coating
Description
Ceram C3 is a high-performance composite material for repairing and
protecting all metal surfaces which are subject to abrasion, corrosion,
cavitation and chemical exposure. Ceram C3 is applied with a coating
thickness of 3 mm. It does not shrink and consists almost entirely of
solids. Ceram C3 contains a high percentage of carbides for use under
extremely abrasive operating conditions which involve complex and
expensive repair measures. The material can either be used for restoring abraded metal surfaces or as a preventive coating which is superior to the original metal with regard to abrasive strength. Ceram
C3 can be used instead of metal applications, rubber fillers, etc.
Composition
Base compound: A modified polymer consisting of two components
Reinforcement: a mixture (protected by proprietary rights) made up
of aluminium oxide and silicon carbide particles.

Temperature monitoring
Standard explosion-certified motors must equipped with a temperature monitoring option. This monitoring can take place using bimetal
strip sensors or PTC sensors.
The standard temperature monitoring unit is always designed as a 1circuit monitoring unit, i.e. when the maximum winding temperature
is reached, the motor must be switched off!
The temperature monitoring unit can be designed as an optional 2circuit monitoring unit, i.e. when the lower temperature is reached, a
preliminary warning is emitted. Deactivation is only necessary if the
maximum winding temperature is reached.
The temperature monitoring unit must be connected in such a way
that when the maximum winding temperature is reached, the motor
is deactivated and reactivation is only possible if the release button
was actuated manually.
When the lower temperature is reached (2-circuit monitoring), a preliminary warning is possible or deactivation with automatic reactivation.
Non-immersion of the motor in the sump or dry well installation of
dry motors
These motors may only be non-immersed or dry well installed if there
is a 2-circuit temperature monitoring unit!
Frequency converter operation
For operation on a frequency converter, it must be ensured that the
internal winding temperature monitoring unit (bimetal strip sensor or
PTC sensor) can be connected.
Sealing chamber control
The units can be equipped with an external sealing chamber control.
This can also be retrofitted. If the unit is equipped with external sealing chamber control, it must be connected to an intrinsically-safe
electric circuit.
Ex-zone definitions
The Ex-zones are clearly defined in the respective standards. The
identification of the zones in the operating area of the units must be
performed by the operator. When ordering, indicate which Ex standard you are using and in which zone you would like to operate the
unit.

Jet cleaners
Cleaning rainwater basins
In mixed water sewer systems, rain spillway basins are placed upstream of the water treatment system. They serve as buffers between the sewer system and the water treatment system. In the
event of a hydraulic overload, these basins take up the surge of water
with its high amount of wastewater, temporarily store the rainwater,
and after the rainfall dies down, they release the rainwater in accordance with the maximum water treatment system capacity.
causes a turbulent flow, which, in turn, prevents solids from depositing.
The rainwater is particularly severely contaminated after long dry
spells. Due to the long emptying times, there are deposits in the basin. After emptying the basin, these deposits must be removed, since
otherwise the sedimentation layer will begin to decay, which can result in strongly unpleasant odours.
In order to keep the basin cleaning problem under control, a number
of basin cleaning devices have been developed and applied, like mechanical evacuation, rinsing/dumping or jet cleaning devices. The
cleaning equipment, some of which is very complex, make a considerable improvement, but all have one thing in common: They only are
put into action when the basin is already empty.
All of these solutions did not achieve satisfactory cleaning results.
The water treatment system personnel still had to clean the basin by
hand, which was very time-consuming.
Function of the jet cleaner
Due to the jet cleaner, a type of cleaning has been developed for rain
basins which brings together a number of advantages. The jet cleaner
is put into operation already during the start of draining the rain spillway basin. It suspends the solids and dirt particles. These leave the
basin together with the water.
The Wilo jet cleaner consists of a Wilo submersible sewage pump
with injector, air suction pipe and jet pipe. The jet cleaner can be installed in nearly any new basin and can be retrofitted in existing basins.
Advantages of the jet cleaner
Due to the onsite down slope from the basin to the drainage channel
of 2-3%, there is an equivalent return flow during the circulation
process. During this process, organic and inorganic substances are
stirred up and conveyed to the drainage channel. In addition to the
cleaning effect, the water is also enriched with oxygen. This side-effect is significant since the water cannot become putrid when it is in
the basin for a long period.
This means:
• No odour emission due to escaping gases
• No contamination of the water treatment system by foul water,
which saves energy when cleaning the sewage water
• Elimination of a hazard of the downstream channels due to hydrogen
sulphide
• Prevention of the development of sewer slime
• No use of external water for the cleaning process. Rainwater is used.
• The cleaning process already begins when the basin is drained and
continues until the basin is drained completely.
• The dirt particles are distributed almost evenly to the out-flowing
basin water.
• The water treatment system is not subject to a flow surge.
• The basin walls are washed off by the wash of the waves.
• The rainwater is constantly enriched with oxygen. As a result, there is
no formation of hydrogen sulphide and no unpleasant odours.
• Breaking down and dissolving organic coarser solids.
• Low investment and maintenance costs, and longer service life of
equipment.
• Overall reduced operating costs due to efficient operation and fully
automatic operating sequence.
Basin design
For using the jet cleaner as a cleaning device, the following design
features should be observed when planning a rainwater basin:
Rectangular basin
The Wilo submersible sewage pump sucks the rainwater out of the
drain channel and pumps it through the injector nozzle via the jet
pipe and back into the basin.
According to the principle of the water jet pump, air is sucked simultaneously via the air suction pipe during this operation. The sucked
air is mixed with the rainwater in the jet pipe. The exiting air/water
drive jet is under high pressure and reaches deep into the basin. This
• The ideal relationship between width and length is 1:2
• The bottom of the basin should be horizontal without any transverse
inclination, but designed with a longitudinal inclination of 2-3% to
the drainage channel.
• The volume of the drainage channel is to be adapted to the basin size
and should include a usable volume of at least 3% of the basin area;
the drainage channel is for taking up inorganic solids and as a water
reservoir for the remaining cleaning of the bottom of the basin. The
235
Consulting guide
Jet cleaners
inclination in the channel should be as steep as possible towards the
outlet flap or to the drainage sump (5%).
• The basin should be drained as quickly as possible. While this is guaranteed during the pumping process, when draining via the outlet
flaps it must be ensured that these are installed at a height that is
sufficient to prevent them from being blocked by the external water
level during draining.
• The basin inlet is to be placed on the side of the outlet channel. If
there are minor deposits in the channel from the last cleaning operation, they are rinsed off during the aeration process.
• The jet cleaner is installed on the bottom of the basin directly next to
the drainage channel.
Round basin
• In the case of the round basin, the bottom must be horizontal without any transverse inclination and with an inclination of 2-3% in relation to the basin wall (like a disc) on one side.
• The round basin should also have a rinsing channel.
• The other design features of the rectangular basin are to be applied.
Technical data with design criteria
When selecting the jet cleaner, observe that the energy density
should be 30-40 W/m3 (in relation to 30% of the basin's volume).
The motors are also available in Ex version. Fastening mechanism and
jet pipe are made of hot-dip galvanised steel or stainless steel.
Control and switching systems
The cleaning operation is always automatic. Depending on requirements, the jet cleaner works intermittently or in permanent operation
initially. If a defined remaining water level has been reached in the
basin, the cleaning process runs in permanent operation until the basin is completely drained.
In the switching system, all switching, control and display devices are
installed which are required for the function and monitoring of the
cleaning equipment. Further basin monitoring and recording equipment can be additionally installed. The electro-pneumatic level control, electric capacitive control or the echo-sounder control are recommended as jet cleaner controls.

Grit collector pumps
A grit chamber is a sedimentation tank for removing course, settleable contaminants from the sewage, such as sand, stones or bits of
broken glass. These substances would easily lead to operational malfunctions in the water treatment system (wear, clogging).
Clearing out the grit chamber therefore poses extreme demands in
terms of the wear resistance of the pump. Furthermore, solidified
sand deposits are to be loosened up and the unit must be frost- and
weather-proof.
Therefore, sewage pumps are used increasingly in sand-catcher systems. For this area of application, Wilo offers its proven submersible
sewage pumps of the type: Wilo-EMU FA…WR. The submersible sewage pumps are submersible and can be directly submerged in the fluid. Thus, suction problems can be avoided and a machine housing is
not necessary.
For this application, the Wilo submersible sewage pump is equipped
with a vortex impeller and a mechanical stirring device. The stirring
device is screwed directly onto the impeller. It consists of a smooth
pipe cylinder and a mixer head, which is ground s-shaped on the front
surface.
The sand is thus only stirred up in the area of the pump inlet. Solid
deposits are loosened up and can be pumped. Due to the narrowly
limited flow zone, the settling of sand is not disturbed. The smooth
pipe cylinder can usually flush long fibrous substances away on its
own. Since the mixer head is subject to a high amount of wear, it is
made of the chilled cast iron material, Abrasite.
The combination of suitable wear-proof materials and coatings ensures long-term and trouble-free operation.
