The performances of the membranes made by the c-TIPS method are superior to that made by the NIPS or the classical TIPS method using the same materials. It can greatly solve the problem of the membrane?s easy broken. The SVF membrane modules offer the following features:1,Longevity 2,Robust membrane (patented technology)3,Permanently hydrophilic membrane (proprietary technology)4,Oxidation-inert membrane 5,Air lift recirculation (patented technology)6,Soft potting (patented technology)7,Low operation pressure8,Better permeate distribution(for steady flux)
