Pressure Sand Filter

A typical pressure sand filter consists of a pressure vessel – this could be either vertical or horizontal – fitted with a set of frontal pipe work and valves, graded sand supported by layers of graded under bed consisting of pebbles and silex, 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. Pressure Sand Filter is also available in ASME and IEI Good Engineering practices. MOC is MS, MSRL and MSEP. Frontal pipe works are available in MS, MSRL.
