[0003] After reverse osmosis operation for a period of time, reverse osmosis membrane element will be polluted by suspended solids, insoluble salts, colloids and other substances that may exist in feed water. The most common of these pollutions are calcium carbonate precipitation, calcium sulfate precipitation, metal oxide precipitation, silicon deposits, inorganic or organic sediment mixture, microorganisms and other pollutions. The nature and speed of pollution depend on various factors, such as feed water quality and system recovery rate. Usually, pollution develops gradually, and if not controlled early, the membrane element will be damaged in a relatively short period of time. When the membrane element is confirmed to be contaminated, timely cleaning can ensure the reverse osmosis water production and water quality. In addition, if some pollutants are not cleaned in time, they cannot be thoroughly cleaned after a long time, resulting in very limited cleaning effect. In case of serious pollution or complex pollutants, offline cleaning is recommended in time.
