How to clean the reverse osmosis membrane?
It can be cleaned with sodium hypochlorite and formaldehyde solution. For biological pollution, different treatment measures shall be taken according to the material of reverse osmosis membrane. Aromatic polyamide membrane can be cleaned with 1% formaldehyde solution. Residual chlorine to prevent bacterial reproduction. For the cleaning of biological pollution of reverse osmosis membrane, the biological content of raw water can be reduced as much as possible in the pretreatment stage. Conventional cleaning methods that we can usually use include chlorine or hypochlorite, ozone, ultraviolet light, etc. Non oxidizing bactericides such as DBNPA or isothiazolinone can also be used to stimulate reverse osmosis membrane systems. At the same time, we should pay attention to that once we find that the reverse osmosis membrane can be biologically contaminated, once sterilization and chemical cleaning are carried out in time, the reproduction of these organisms can be prevented and the pollution degree can be increased. Membrane element. In addition, we use a reverse osmosis membrane biological fouling cleaning method for a period of time, and try to change another method for operation, which can prevent the biological production of drug antibodies and reduce the cleaning effect.
