It is recommended to clean the Ro System Component if they are contaminated, either before long-term shutdown or as regular routine maintenance.
After a period of normal operation, the ro system component will be contaminated by suspended substances or insoluble salts that may exist in the feed water. The most common pollutants are calcium carbonate precipitation, calcium sulfate precipitation, metal (iron, manganese, copper, nickel, aluminum, etc.) oxide precipitation, silicon deposit, inorganic or organic deposition mixture, NOM natural organic matter, synthetic organic matter (e.g. scale inhibitor/dispersant, cationic polyelectrolyte), microorganism (algae, mold, fungus), etc.
The nature and speed of pollution depend on various factors, such as feed water quality and system recovery rate. Pollution usually develops gradually. If it is not controlled as soon as possible, the membrane element will be damaged in a relatively short period of time.
The cleaning cycle of the contaminated ro system component depends on the actual situation on site. The normal cleaning cycle is every 3-12 months. The steps for cleaning ro system component are as follows:
1. Pump clean, free chlorine-free reverse osmosis product water from the cleaning tank (or corresponding water source) into the pressure vessel and drain for several minutes.
2. Use clean product water to prepare a cleaning solution in the cleaning tank.
3. Circulate the cleaning solution in the pressure vessel for 1 hour or preset time.
4. After cleaning is completed, drain the cleaning tank and wash it, then fill the cleaning tank with clean product water for further washing.
5. Pump clean, free chlorine-free product water from the cleaning tank (or corresponding water source) into the pressure vessel and drain for several minutes.
6. After flushing the ro system component, run the reverse osmosis system with the product water discharge valve open until the product water is clean, free of foam or detergent, usually for 15-30 minutes.
After all, plastic products are produced by human beings, so human factors are also very important. The quality of plastic parts produced by skilled and experienced machinists is often better than that of inexperienced novices.
