Industrial 8-inch Extra Low-Pressure RO Membrane for Water Treatment Purifier System


How to clean reverse osmosis membrane?

It can be cleaned with sodium hypochlorite and formaldehyde solution. For biological pollution, different treatment measures should be taken depending on the material of the reverse osmosis membrane. The aromatic polyamide membrane can be cleaned with a 1% concentration formaldehyde solution. residual chlorine to prevent bacteria from multiplying. For the cleaning of reverse osmosis membrane biological fouling, we can mainly reduce the biological content of raw water as much as possible in the pretreatment stage. The conventional cleaning methods that we can usually use include chlorine or hypochlorite, ozone, ultraviolet rays, etc. . Non-oxidizing bactericides such as DBNPA or isothiazolinone can also be used to irritate the reverse osmosis membrane system. At the same time, what we need to pay attention to is that once we find that the reverse osmosis membrane can be biofouled, once it is sterilized and chemically cleaned in time, it can prevent these organisms from multiplying and increase the degree of pollution to the membrane elements. And we use one reverse osmosis membrane biological fouling cleaning method for a period of time, try to replace another method to operate, which can prevent the biological production of pharmaceutical antibodies and reduce the cleaning effect.
