Different types of membrane filtration
WebThe removal efficiency of several pharmaceutically active compounds from two different surface water types was investigated. Two different nanofiltration (NF) membranes (Trisep TS-80 and Desal HL) were first studied at low feed water recoveries (10%). In a second phase, the combination of an NF unit at higher feed water recovery (80%) with … WebWhat is membrane and types of membranes are there?
