Aquaflex 55 ultrafiltration (UF) membranes
are an excellent filtration technology for the
treatment of surface and ground water to
potable or process water standards and for
effective effluent polishing. The hollow fiber
membranes on the inside provide superior
separation performance and effectively
reject bacteria and viruses. Each module
with a membrane surface area of 55 m² is
installed vertically and connected directly to
feed and filtrate headers.
Pentair X-Flow’s ultrafiltration membranes
know an inside-out flow configuration with
two modes of operation: dead end flow
or recirculation flow. Recirculation flow
is applied to increase the turbulence on
the membrane surface. Both modes of
operation are discontinuous with alternating
filtration (production) and backwash
(cleaning) steps. In the filtration step feed
water is forced through the fibers, and in the
backwash step some of the filtrate is forced
back through the membranes to remove any
solids. The inside-out configuration offers a
high performance (flux/tmp) at a low energy
and chemical consumption.

Compared with traditional sand filtration,
ultrafiltration membranes offer the
following advantages:
• Delivers a high filtrate quality
• Yields substantial savings in space, cost
and energy
• Suited to build scalable systems
• Easy to integrate with other processes
• Provides a reliable single barrier for
bacteria and viruses
• Protects public health, operators & the
environment
