General Information

Pentair X-FLOW XF75 is an ultrafiltration, used for the production of process and potable water from surface water, for wastewater polishing and reuse, in the pre-treatment of large SWRO plants, and in large-scale drinking water production. The XF75 module can be utilized in Pentair’s unique solutions Aquaflex and X-Line.

The XF75 membrane element has 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

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%). Membrane modules should be stored in a dry, normally ventilated place, away from sources of heat ignition and direct sunlight. Storage temperature should be between 0 and 40 °C.
