Hello Nomundari, In reverse ...

Hello Nomundari,
In reverse osmosis, the backwashing is said ``flushing´´ due to the fact that the water flows in the same direction as operation. It´s completely neccesary to make a flushing everytime the RO stops, or every 12 hours working.
How long the membranes should be replaced depends on the inlet water quality and depends on whether you make the chemical cleaning when it´s needed.
I normally use the normalized permeate flow, which includes mathematical formulas about pressure, conductivity, temperature, etc. to know when the chemical cleaning is neccesary.

If you need some example, I can give you some sheet to use. It´s very easy. Taking care of this, the membranes life will increase.
Best regards,
Pablo
