A periodic top-up of, sand, in the bed is required as the, backwashing, process causes, sand, loss. To assist in cleaning the bed, the, backwash, operation is often preceded by air scouring through the underdrain system agitating the, sand, with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.
