How to clean the reverse osmosis membrane?
What are the methods of cleaning the film
1, flushing method:
Before soaking, it is necessary to wash the reverse osmosis membrane, because the positive and negative pressure resistance of the RO membrane is not the same, so under normal circumstances is to reverse wash
2, chemical cleaning:
Chemical agents are added and soaked to dissolve and oxidize scale by chemical reaction between chemical agents and polluting substances, and finally achieve the purpose of scale removal.
The reagent is placed at the water inlet, and the concentrated liquid and ultrafiltrate are returned to the cleaning liquid container, so that they are recycled and then discharged, and finally washed with clean water.
3, pressure flushing method:
Close the outlet valve of the reverse osmosis membrane before cleaning, and then open the wastewater discharge valve to increase the flow rate of water on the surface of the membrane, which can also remove the scale material deposited on the membrane.
