See Design Criteria - Filters. Typically, the volume within the practice can be less than the total water quality volume for filter designs. Step 9. Compute volume within practice: Volume within filter bed (V f): V f = A f (d f) (n); n = 0.4 for sand (Porosity) V f = (473 sq ft) (1.5') (0.4) = 284 cubic feet

The pressure filter is operated at elevated pressures, thus prolonging the filter cycle and/or increasing the rate of flow of water through the filter. Gravity filters are commonly operated at 2 GPM/sq ft *, whereas pressure filters are operated at 3 GPM/sq ft and higher. The rapid sand filter is operated with clarification ahead of the filter.
