Pressure Sand Filter

Overview:

Pressure Sand Filter is used for removal of suspended solids & turbidity from Water & Wastewater. We, at NK offer Series of filters at a low cost, reliable and efficient way to filter your water.
Our unique design of Pressure Sand filter ensures the maximum utilization of the surface area; lesser pressure drop across the filter bed and effective removal of the impurities.
NK Filters are available in diameters from 0.225 mts. to 4.0 mts. (vertically) and in length from 3.0 mts. mm to 11 mts. (Horizontally) with flow rates up to 350 m³/hr. these rugged, pre-engineered, pre-assembled units minimize installation and start-up costs. Whether you require RO feed process water or filtered water, NK can fulfil applications requirement

Working Principle:

Raw water is passed through the pressure sand filter, the filter media (Fine quartz sand) is supported on gravel & pebbles bed 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 bed. Clear water can be collected from the outlet of filter.
