Fouling Resistant RO Element
Fouling Resistant RO Element is developed for complex water quality.This element with special membrane preparation process, it improved the hydrophilia,charge characteristic and roughness, can effectively reduce the breeding of Biofouling and adsorption of pollutants in the membrane surface.The element is applied a special 34 mil spacer design, which effectively reduced fouling and pressure drop, with more durable on cleaning can extent the service life.
Fouling Resistant RO Element normally suitable for treatment of complex water source with TDS less than 10000ppm.It is mainly used for purification of surface water, mining waste water, municipal reclaimed water, industrial waste water,RO brackish water.etc.It increased the degree of polymerization of aromatic polyamides and the thickness of separation layer.Meanwhile, a special 34 mil channel design is adopted, which further increased the rejection rate, reduces the pressure drop and enhances the firmness of element during cleaning.
