2. Rapid sand filtration is a technique common in developed countries for treating large quantities of drinking water. It is a relatively sophisticated process usually requiring power-operated pumps for backwashing or cleaning the filter bed, and flow control of the filter outlet.
Pressure sand filters typically consist of a tank filled with layers of graded sand and gravel. The top layer usually comprises coarse sand, followed by layers of finer sand and gravel below. The filter media work together to trap and remove suspended particles and impurities from the water passing through.

The primary function of sand filters is to trap and remove solid particles from wastewater, thus clarity and purity levels post-filtration are key indicators of performance. For instance, intermittent sand filters are …
Pressure filters require finer grades of sand, grade 22/36 being the finest grade used. The pressure filter height should be less than 5 m. When used in downflow, design loadings and limitations are the same as RGFs, but the vessel (especially if vertical) should not exceed 3 m in diameter, to avoid flow distribution problems.
