Q-SEP is an advanced ultrafiltration membrane that removes suspended solids, high molecular-weight solids, bacteria, viruses and cysts. This PES membrane and module design utilizes high-strength hollow fibers less prone to breakage along with high membrane packing density in a unique fiber housing design. Applications for Q-Sep include: surface water treatment, seawater treatment and wastewater treatment/water reuse. These membranes are NSF certified.
