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

Although great alone, the best performance

is achieved when the Aquaflex 55 module is

used with the Aquaflex skid design. With

its excellent modular characteristics, the

Aquaflex skid offers a nominal capacity of

up to 800 m³/h by featuring up to 6,600 m² of

membrane surface.

The skid layout offers an optimum

physical footprint and provides convenient

accessibility to all modules for fast

Worldwide, governments, municipalities

and industries face the challenge of safeguarding

current and future drinking water

requirements. Not only the allowable levels

for turbidity and microbiology are being

lowered for potable water, but also new

limits are being established for viruses

and chlorine resistant organisms, such as

Cryptosporidium and Giardia.

With Aquaflex 55, Pentair X-Flow offers

a solution to produce potable water that

meets the highest standards for turbidity

and microbiology.

MIRACLE

o

Because of rising costs and growing supply

challenges, more and more industrial and

agricultural customers are using surface

water instead of potable water.

Pentair X-Flow’s hollow fiber ultrafiltration

(UF) membranes produce process water

that can either be used directly, if salinity

and dissolved substances are within limits,

or be fed to a reverse osmosis system, to

remove salinity and dissolved substances.

Polished effluent from wastewater

treatment plants can be re-used for low

grade non-potable applications. For this,

Aquaflex 55 offers a reliable solution as the

hollow fiber ultrafiltration membrane meets

the highest standards for turbidity and

microbiology.

The membranes can either be installed

as a single treatment step, if salinity and

dissolved substances are within limits, or

as pre-treatment for a reverse osmosis

system , to remove salinity and dissolved

substances.
