The working principle of a Sand filter is very straight forward. In a sand filter, water is gone through multi layers of filter media The contaminants in the water are caught in the media bed and sifted water goes into the release manifold at the base of the tanks. After back washing, the filter is flushed with raw water and after the required nature of water is accomplished the filter is returned to support. Sand filtration is frequently used and very robust method to remove suspended solids from water. The filtration Media consists of a multiple layer of sand like fine / medium / coarse / pebble. Sand filters can be supplied in different sizes and materials both Manual operated or fully automatically. Raw water pump is used for generating operating pressure in the sand filter.
