The Zhishui series external pressure ultrafiltration membrane is made of PVD hollow fiber membranes prepared using Motian’s proprietary hydrophilic modification process. It features high flux, high hydrophilicity, and resistance to chemical cleaning agents. The Zhishui series external pressure membrane modules offer excellent product performance and can effectively remove suspended solids, colloids, and microorganisms from water. They are widely used in groundwater and surface water purification, as well as pretreatment of low-pollution wastewater.
