The process of air scouring agitates the sand with a scrubbing action, loosening the intercepted particles. After backwashing, the filter is ready to be put back into service. For a 500 MW TPS, the typical backwashing flow rate would be, between 25 to 30 m 3 /hr/m 2 of bed area, and the, air-flow rate would be 50 m 3 /hr/m 2 of filter bed area.
