The process of filtration on involves the flow of water through a granular bed, of sand or another suitable media, at a low speed. The media retains most solid matter while permitting the water to pass. The process of filtration on is usually repeated to ensure adequate removal of unwanted particles in the water. We offer a wide range of filtration on systems standardized on the basis of specific velocities for each type of filter. Multi Grade Sand Filters, Activated Carbon Filters and Iron Removal Filters are available with single 5-way valve operation & multiple valve operation depending on the flow rate & the application. Filters are available in MS (painted), FRP & HDPE construction.
