The suspended iron water is passed through iron removal plant. The filter media is supported on gravel bed that consists of multiple layers of progressively larger sizes of manganese Di oxide, graded quartz sand, fine sand, super fine block silica and pebbles, which retain the suspended iron particles. During the filtration cycle the filter bed retains the dirt and suspended iron particles from the water and accumulates within the filter bed. As the filtration progress the filter media gets loaded with the retains particles their 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. After back washing the filter is reused with raw water and after the quality of water is achieved the plant is put back into service.
