Apr 01, 2009 · Two flat-sheet membranes were tested in the VEDCMD experiments. The first was a laminated membrane made with a polytetrafluoroethylene (PTFE) active layer over a polypropylene (PP) support mesh and the second was asymmetric PP membrane. Both membranes have a nominal pore size of 0.22 μm and both were acquired from GE Osmonics (Minnetonka, MN
