发明名称 METHOD OF TREATING POLYAMIDE MEMBRANES TO INCREASE FLUX
摘要 The flux of a composite reverse osmosis or nanofiltration membrane having a polyamide discriminating layer is enhanced in a one-step process in which the discriminating layer is treated with ammonia or certain alkylamines. It is possible to control both rejection rate and flux of the membrane as well as convert reverse osmosis membranes into nanofiltration membranes.
