Multigrade Sand Filter
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
Multigrade Sand Filter (PSF) and Multigrade Sand Filter (MGF) are media used in vessel and velocity variation.
