What Is The Backwashing Frequency For Activated Carbon Filters?

The backwashing frequency of activated carbon filters mainly depends on Raw water quality and operating conditions :

Under normal water quality conditions It is usually backwashed once a day.

When the water quality is poor or the pollution load is high It may be necessary to backwash 2-3 times a day.

Backwashing frequency is generally based on The pressure difference between the inlet and outlet reaches 0.1-0.15 MPa. Or the deterioration of the effluent water quality (such as excessive turbidity or residual chlorine) is the trigger signal.

If there are no significant changes in pressure differential and water quality over a long period of time, it is recommended that... Forced backwashing once every 7 days at most To avoid clogging of the filter media.

In practical applications, the backwashing frequency should be flexibly adjusted according to the specific water quality and equipment operation to ensure the stable operation and adsorption effect of the activated carbon filter.
