NATCO Hiperfilter high efficiency, deep multi-bed filtration

Hiperfilter SFX Multi-Media Filter
NATCO Hiperfilter high efficiency, deep multi-bed filtration at
high flux rates.
Introduction
The Serck Baker Hiperfilter has been
associated with high efficiency filtration
for more than 25 years. Now part of the
NATCO range, the Hiperfilter SFX
continues to set the standard.
The enviable reference list includes over
200 projects for onshore, offshore, fixed
and floating oil and gas production
platforms, refineries, petrochemical plants
and potable water supply.
NATCO’s Hiperfilters, SFX, DFX and VFX
can be found working efficiently in North
and South America, Europe, the Middle
East, Africa, India and the Far East.
High Efficiency
Offering high efficiency, deep multi-bed
filtration at very high filtration flux rates,
NATCO’s Hiperfilter SFX are specifically
designed to provide long, reliable service
over a wide range of operating
conditions.
NATCO’s Hiperfilter SFX has been
designed to meet and exceed the
theoretical efficiencies of an upflow filter
with the additional advantage of being
able to operate at much higher fluxes.
The result is a more compact and robust
unit.
Large grain size, low density upper media
is combined with a small grain size,
density lower media to give true “in
depth” filtration.
NATCO’s Hiperfilter SFX triple media filter
offers all the benefits of the Hiperfilter SFX
dual media filter, specifically for
applications with high solids loadings.
The design of the proprietary upper and
lower distribution/collection systems
eliminates filter dead spots and the
problems of mudballing, channelling,
poor water/effluent quality and media

loss, often found in lesser designs.
Because of the flexibility within the design
of the filters, the units can be configured
to achieve water qualities with removal
efficiency of up to 98% at 2µm.
Low Operating Costs and a Safer
Working Environment
Because of the inherent reliability and
efficiency of NATCO’s Hiperfilter SFX,
chemical requirements are minimized,
downtime is reduced and a low level of
operator assistance is needed. This
substantially reduces overall operating
costs and offers a safer working
environment.
Lightweight Media Filters
NATCO’s Hiperfilter SFX give a 30% plus
weight saving over conventional filters
and are designed for applications where
space and weight are at a premium, such
as offshore platforms.
The Hiperfilter SFX Lightweight media
filter design can be offered on new
applications and can also be utilised to
upgrade existing installations where
increased capacity is required, without the
addition of further vessels.
Oily Water Treatment
Where produced water is to be treated
onshore, for reinjection into the oil
reservoir or where the water is to be
disposed of into an environmentally
sensitive area, the Hiperfilter SFX can be
used for polishing. NATCO has a large
number of such units in operation
achieving free oil levels of below 5ppm at
the outlet.
Alternatively NATCO’s PowerClean
Nutshell filter can be considered for this
duty (see separate brochure).

Flexible Configurations
horizontal filters offer the customer a
flexibility in configuration to meet their
specific needs.
On large capacity applications, typically
over 300,000 bpd, approximately
2,000m3/hr, where large banks of vertical
filters would be impractical, horizontal
filters are available. Engineered on the
same principles, high standards and
efficiencies of NATCO’s vertical filters,

Titanium or 254 6Mo, making them
ideally suited for the harshest of
environments.
A Choice of Materials
NATCO filters are available in a wide
range of materials. For example, vessel
internals can be manufactured from 316L
Axsia’s filter applications include:
Seawater Water Injection
Process Water
River or Aquifer Injection
Potable Water
Refinery or Industrial Wastewater
