General Information

Pentair Aquaflex 40 Ultrafiltration Membrane is an ultrafiltration module, used for production of process and potable water. Typical applications are the filtration of surface water, potable water and WWTP effluent. Mode of operation is feed-and-bleed with a minor crossflow or dead-end mode with regular backwash (permeate only) and chemically enhanced backwash.

The Aquaflex 40 modules have the following general properties and characteristics:

Hydrophilic membrane composed of a blend of polyvinylpyrrolidone and polyethersulfone
A nominal pore size of 20 nm
Structure asymmetric/microporous
High performance and a very good anti fouling behaviour
Typical permeate quality SDI<3, turbidity <0,1 NTU
Membrane filtration provides 99.9999% (LOG6) reduction of bacteria (Pseudomonas diminuta) and 99.99% (LOG 4) reduction of virus (MS2 colifages) by mechanical means. EPA Est. No. 090374-NLD-001

Operation guidelines

To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasings. Bring the module or element back to ambient operating temperature slowly (max. value 3 °C/min).

Storage

New membrane modules can be stored as supplied in the original packaging. The membrane modules contain an aqueous preservation solution of glycerine (20wt%) and sodium metabisulfite (1wt%) to prevent dehydration and control bacterial growth. The membrane modules are packed in plastic bags which are vacuum sealed to keep the moisture in the module. Membrane modules should be stored in a dry, normally ventilated place, away from sources of heat ignition and direct sunlight. X-FLOW BV Storage temperature should be between 0 and 40 °C.
