Cleaning reverse osmosis water treatment equipment need those water treatment chemicals?

In the normal operating conditions of the equipment, reverse osmosis membrane may also be inorganic scale, colloids, microorganisms, metal oxides and other contaminants, the deposition of these substances on the membrane surface will cause water purification equipment reverse osmosis device output decreased or desalination rate decreased, differential pressure increased, and even the membrane caused by the irrecoverable damage, therefore, in order to restore the very good water permeability and desalination performance, the need for chemical cleaning of the membrane.

The general equipment is best 3 ~ 12 months to clean once, if you have to clean once a month, then this means that companies should improve the pretreatment system, adjust the operating parameters. If you need to clean once every 1 to 3 months, then you need to improve the level of operation of the equipment, whether you need to improve the pretreatment system is more difficult to judge.

Reverse osmosis water treatment equipment in the selection of some of the precautions for cleaning drugs:

1, in strict accordance with the production of equipment manufacturers to specify the list of drug selection, dosage, PH value, temperature and contact time.

2, the use of the least aggressive drugs to complete the cleaning work, these do will extend the service life of the membrane.

3, in adjusting the PH value, must be prudent to extend the life of the membrane. The less aggressive pH range for pharmaceuticals is 4 to 10, and the maximum allowable pH range is 2 to 12.

4. Do not mix acids and bases. Thoroughly flush the system to drain the last cleaning solution before adding the next solution.

5. Rinse out the detergent with high pH produced water.

6. Confirm compliance with proper wash solution handling requirements.
