Ultrafiltration (UF) is a membrane process used to remove suspended solids, colloidal matter, high molecular-weight substances, bacteria and viruses from various feed water sources. UF membranes can achieve a low and consistent silt density index (SDI) and are often used as pretreatment for reverse osmosis using surface water, seawater and biologically treated wastewater as feed source.
Q-SEP UF membranes incorporate high strength hollow fibers which deliver superior performance without the risk of fiber breaks. These UF membranes are made from a hydrophilic polyether sulfone (PES) material with excellent low fouling characteristics and operate under a pressurized inside-out flow configuration for superior performance. Q-SEP modules are manufactured with NSF-PDWEP certification for drinking water application.
