Drinking and Process Waters from brackish
and sea water by Reverse Osmosis Systems
Reverse Osmosis is an excellent system for the
desalination of brackish and sea water with low
investment and running costs.
Our company offers both systems for
brackish and sea water desalination plants:
Skid and or container mounted plants.
Our production range various from
50 m3/d up to 500 m3/d (13210 gpd- 132100 gpd)as
container plants and skit mounted plants up to 1200
m3/d ( 317000 gpd).
Off course several plants can run in parallel for higher
need of water.
Our systems are complete with pre and post
treatment. We always try to find the best
solution for each customer and his individual wishes
and requirements.
Filtration
To protect the membranes from suspended matters
we are offering Multi Media and Activated Carbon
filters with low speed. The backwash of the systems
are differential pressure controlled. The valves are
single compressed air commanded diaphragm or
butterfly valves with or without position indicator
switches.
5 micron cartridge filters are made from reinforced
PP, with high quality Puro melt cartridges
with dual filtration rates for long cartridges life, 20 – 5
micron.
Technicians
Our highly qualified technicians with their team,
offering 17 years of experience and resolve water
problems.
Pre – treatment for RO plants
Our calculations are based on 3 years running time.
Life time of RO elements can be much
longer by well designed Pre – treatment. Therefore
BKG applies proper filtration systems
with low speed, disinfection before conducting the
water to the RO plant to avoid membrane fouling
because of:
Scaling
Colloids
Suspended and dissolved organics
Biological matters.
Racks with membrane vessels
Our racks are made from SS and colorless painting
against highest corrosion protection.
Technical Features
Dosing Systems
For RO plants we equip our dosing systems with:
low level switches, pre alarm for refilling dosing tank
flow controller, if chemicals are not metered plants
are stopping automatically.
Dosing systems are used for metering of:
Flocculation, Chlorine, Antiscaling, Destroying free
Chlorine, Disinfection,
pH Adjustment

Piping
Low pressure piping is PVC or PP and high pressure
piping 316 L for brackish water and
1.4539 or duplex SS for seawater plants.
Membrane vessels from high corrosion resistant GRP
with PP liner for high UV protection of membranes.
PP liner are highly chemicals resistant for chemical
membrane cleaning.
Pumps for high pressure
Smaller plants up to 100 m3/d with piston pumps
Medium plants with Grundfos BMET with and without
energy recovery systems
Larger sizes with duplex SS with energy recovery
systems
PLC control and Instrumentation
For the controlling of brackish and sea water plants
we are using PLC controller and we offer all
necessary measurement equipment to run a plant
save, such as:
pH, conductivity, free chlorine, turbidity, flow,
temperature and pressure control with transmitters
with 4-20 mA signals. The switch board panels can
be equipped as well with modems for transmitting of
disturbing or requested maintenance signals, such as
cartridge changing, refilling dosing tanks
to Mobil or normal phone,
Measurement Instruments
pH, conductivity, free Chlorine, turbidity, Rhedox,
Membranes
are from well known manufactures like DOW and
Torray up to 84 bar (1200 psi) working pressure for
highest salt contents.

Permeate pump stations
Permeate pumps station can be single pump, duplex
or multi pump station with or without
frequency control.
BKG offers complete systems including lead
installation service, service setting, maintenance and
training, Antiscaling chemicals.
Process Operation
Operation of PLC controlled RO plants is easy,
because the plants are self controlled.
All eventual disturbing will be indicated on the OP
(operation panel) or on the touch screen.
The service operator should carefully follow the
maintenance and service instruction for a longer
membrane life.
For this reason we offer qualified training to the
service operators.
Membrane permeate and cleaning stations
Fields of Application
Drinking Water for one or several houses, Villages,
Hotels, Restaurants, Holyday villages
Irrigation Water
Industrial use
Process water for many application such as boiler
feed, Pharmaceutical use, cosmetically, steel
production.
Water bottling, soft drink industry and many other.
for smaller plants we offer a duplex system which can
be used for permeate flushing
of the complete system to protect plant against
corrosion and scaling. Same system can
be used as well for chemical cleaning of the
membranes.
For larger systems we are offering single membrane
cleaning system with pump, temperature
control, flow control, fine filter.
