We Ion Water Machineries Pioneer in field of iron removal filter manufacturer and supplier in West Bengal since 1967. The suspended iron water is passed through iron removal filter the filter media is supported on graded gravel bed that consist of multiple layers of progressively larger sizes of manganese Di-oxide, graded quartz sand, fine sand, super fine black 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 with in the filter bed. As the filtration progress the filter media gets loaded with the retained 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. After back washing the filter is rinsed with raw water and after the quality of water is achieve the filter is put back into service. When water enters the iron removal filter it passes through a bubble of compressed air that adds oxygen to it. The water then passes through a filter bed. The filter material enhances a reaction that separates the iron for your water. The soluble flakes of iron that result are then caught by the filter bed. Capacity 50 to 50000 gallon per hour and above.
