Pressure Sand Filter

Pressure sand filter is highly recommended for the removal of suspended & visible impurities like sand, dust particles & heavy metals etc.PSF is an ideal solution for the systems with high sediment, silt, sand, and turbidity.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. Fig shows the arrangement of a vertical and horizontal pressure sand filter.
