RO membrane fouling can cause system performance degradation, component of pressure difference between inlet and outlet, the increase of membrane components replacement. Periodic cleaning for the membrane is effective way to ensure the normal system operation and extend service life of elements of. Through analysis to the reason of concentrated reverse osmosis water system pollution, this article introduces the cleaning of reverse osmosis membrane method, and through two chemical cleaning data of dense water reverse osmosis system, it puts forward the optimal operation measures for concentrated water reverse osmosis system.
