Polymem UF Seawater Ultrafiltration System

Consistent seawater filtration performance


Polymem UF systems function by capturing all particles greater than a certain size on the surface of a membrane. Once a layer of particles (foulants) has formed on the membrane surface and caused a certain pressure drop between the feed and the filtrate, the system is backwashed with filtrate and air. The systems can manage varying feed qualities while still delivering consistent filtrate quality with a silt density index (SDI) < 2.
