Nanofiltration composite polymeric/ceramic membranes prepared from powder waste of ceramic tile kiln remnants

摘要

Novel nano-filtration composite polymeric/ceramic membranes were successfully fabricated. The prepared membranes were prepared using powder from ceramic tile kiln remnants, which contain a high percentage of alumina. Support ceramic membranes samples were formed into discs by using polyvinyl alcohol organic binder. The top layer of the membrane was a polymeric solution of polyethersulfone. The prepared membrane exhibited good performance and the results indicated that the dye separation reached to 99.8% and 99.5% with a high permeate flux of 86 L/m(2) h to 48.2 L/m(2) h under an operating pressure of 8 bar, and the dye concentrations of 50 to 200 ppm, respectively, after 30 min.
