Pressure Sand Filter is highly recommended for the removal of suspended solids & undissolved impurities like dust particles & heavy metals etc. PSF reduces turbidity. 
 Pressure Sand Filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. The sand filters are specially designed to take care of the range of suspended impurities. Our unique design ensures the maximum utilization of the surface area, lesser pressure drop across the pressure bed and effective elimination of the impurities. 
 
 Working Principle:
 
Raw water is passed through the pressure sand filter, the filter media is supported on gravel bed that consists of multiple layers of Graded quartz sand, Fine sand, Super fine white sand and pebbles of progressively larger sizes. During the filtration cycle the filter bed retains the dirt and suspended particles from the water and accumulates within the filter the water and accumulates within the filter bed. As the filtration progress the filter media gets loaded with retained suspended particles, this results in a continuous increase of pressure drop across the filter, when a predetermined pressure drop level is achieved the filter is shut down for cleaning.

 Back Wash
 As the filtration progress the filter media gets loaded with the retain the suspended particles, this results in a continuous increase of pressure drop across the filter, when a predetermined pressure drop level is achieved the filter is shut down for cleaning. The filter media is cleaned by backwash system. After backwashing the filter is rinsed with raw water and after the required quality of water is achieved the filter is put back into service. Depending on the filtered water quality required backwashing is either done with raw water or with filtered water.
