Detailed process of reverse osmosis RO membrane cleaning and offline cleaning of the author of the article online:? Prolonged use causes RO reverse osmosis membrane filtration residual impurities by contamination in the application process, and therefore need to be regularly cleaned to restore performance. Therefore, the user should understand how to clean the reverse osmosis RO membrane to achieve better results. Today I want to introduce the difference between online and offline cleaning of reverse osmosis RO membrane. Off-line cleaning method Off-line cleaning mainly refers to removing the reverse osmosis membrane from the pressure vessel and putting it into a special cleaning equipment for cleaning and disinfection. Special attention should be paid to the cleaning quantity at a time not exceeding 6, otherwise the excess quantity will be seriously reduced Cleaning effect. The off-line cleaning method is a method that is simple and convenient to operate, clean thoroughly, and has a good effect. However, it also has certain shortcomings. When there are many membrane elements, the cleaning time is determined by the membrane elements. Generally, the reverse osmosis RO membrane is more polluted or has an online cleaning effect. This method can be used in poor situations. On-line cleaning method On-line cleaning is mainly to clean the entire reverse osmosis device without taking the reverse osmosis membrane out of the pressure vessel. It is usually designed and used in a larger system. It is a cleaning method that is simple and convenient to operate and has a short time. This method can be used when the reverse osmosis device is less polluted. The cleaning method of the reverse osmosis RO membrane should be selected according to the actual number of membrane elements to be cleaned and the membrane pollution. Only standardized operations can achieve better results.
