STUDY ON THE CLEANING OF SEAWATER REVERSE OSMOSIS POLYAMIDE MEMBRANES

On the basis of the problem of reverse osmosis(RO) membranes fouling in the RO seawater desalination process, three kinds of chemical cleaning agents were studied through lab-scale simulation tests.The affection of cleaning efficiency of RO membranes were discussed under the condition of different concentrations and different time with the three kinds of chemical cleaning agents.
