The P-Series family of polyethersulfone ultrafiltration membrane elements are characterized by a 20, 000
molecular weight cut off and greater than 96% rejection of Cytochrome-C (13,300 MW protein). PW
Elements are used for pretreatment of process water, post treatment of ultrapure water, and for the removal of organics.
