PW Series
Industrial Ultrafiltration – Post treatment of RO and NF
The P-Series family of polyethersulfone ultrafiltra-
tion membrane elements are characterized by a
10,000 molecular weight cut-off and greater than
96% rejection of Cytochrome-C (13,300 MW pro-
tein). PW Elements are used for pretreatment of
process water, post treatment of ultrapure
water and for the removal of organics.

Internal diameter unless specified OD (outside diameter).
3
The element diameter (dimension C) is designed for optimum performance in GE
pressure vessels. Other pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.
