Multigrade Sand Filter also consist of a vertical or horizontal
pressure vessel with a set of frontal pipe work and valves, media
consist of different sizes and grade mixed and supported by layers of
pebbles and gravels, a top distributor to distribute the incoming
water uniformly throughout the cross section of the filter, and an
under drain system to collect filtered water.

This filter performs at a substantially higher specific flow rate than
conventional filters. The basic difference between Pressure Sand
Filter (PSF) and Multigrade Sand Filter (MGF) are media used in vessel
and velocity variation.
