Ultrafiltration (UF) is a membrane process used to remove suspended solids, colloidal matter, high molecular-weight substances, and 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.
QUA Q-SEP® UF membranes incorporate high-strength, hollow fibers that deliver superior performance without the risk of fiber breaks. Q-SEP® UF membranes are available in inside-out and outside-in flow configuration. Both types of membranes have excellent low fouling characteristics. These hollow fiber membranes operate under a pressurized flow configuration for superior performance.
