About Project

After a period of normal operation, the reverse osmosis membrane element is contaminated by suspended solids or insoluble salts that may be present in the feed water. The most common of these contaminants are Calcium Carbonate precipitation, Calcium Sulfate precipitation, metal (Iron, Manganese,Copper, Nickel, Aluminum, etc.) Oxide precipitation, Silicon deposits, inorganic or organic deposition mixtures, NOM natural organic matter, synthetic organic matter(such as: scale inhibitor / dispersant, cationic polymer electrolyte), microorganisms (Algae, Mold, Fungi) and other pollution.

Therefore, we recommend that the membrane components should be cleaned in time. The normal cleaning cycle is every 3 to 12 months.
The general procedure for cleaning the reverse osmosis membrane element

1, Pump the clean, free of chlorine reverse osmosis product water from the cleaning tank (or the corresponding water) into the pressure vessel and discharge a few minutes.

2, Prepare the cleaning fluid with a clean product water in the cleaning tank.

3, Put the cleaning fluid in the pressure vessel and circulate for 1 hour or pre-set time.

4, After the completion of cleaning process, evacuate the cleaning tank and rinse, and then fill the cleaning tank with clean product water for the next washing step.

5, Pump the clean, no free chlorine product water from the cleaning tank (or the corresponding water) into the pressure vessel and discharge a few minutes.

6, After flushing the reverse osmosis system, operate the reverse osmosis system while the product water discharge valve opening until the product water is clean, free of foam or no cleaning agent (usually 15 to 30 minutes).

7, For other special circumstances, please contact us directly.
