The cleaning requirements for reverse osmosis pure water equipment are very high, which means that some filtering devices cannot have any pollution to avoid affecting water quality. What is good to use when cleaning the equipment?

1. EDI cleaning, accompanied by the accumulation of working hours, requires cleaning and disinfection of the EDI control module. This is due to strength or metal material fouling, which can be caused in concentrated water rooms.

2. Timely cleaning of reverse osmosis pure water equipment with high flow rate, low working pressure, and low pH value is beneficial for removing stains adhering to the surface of the membrane, maintaining membrane characteristics, or when the SDI of the machine equipment suddenly rises above 5.5 due to water leakage, bottom pressure cleaning should be carried out, and the equipment should be restarted after the SDI value is adjusted to meet the standard.

3. Cleaning the RO reverse osmosis membrane with bottom pressure for thirty minutes can restore the characteristics of the RO reverse osmosis membrane to a certain extent, but long-term use of this method will still reduce the permeability.

4. Due to the fluctuations in production and manufacturing, it is inevitable that reverse osmosis pure water equipment will often stop operating. When it is stopped for a short or long period of time, protective measures must be taken. Inappropriate placement can cause a decrease in membrane characteristics and cannot be repaired.

5. The mixed fluid dynamics of tap water and gas is used to clean the surface of the membrane under bottom pressure, which takes about 15 minutes. This method has very good practical results in the early stage.

Under all normal operating standards, RO reverse osmosis membranes will also be contaminated by inorganic compound deposits, colloidal solutions, microbial strains, hydroxides, and other environmental pollutants. Therefore, in order to restore good permeability and desalination characteristics, organic chemical cleaning of the membrane is necessary.
