We are Ion Water Machineries most trusted name engaged in manufacturer and supplier of iron removal filter since 1967 in all over India. Raw water generally contains soluble iron in form of ferrous bicarbonate and insoluble form as ferric hydroxide. Water containing ferrous bicarbonate is clear when drawn from a boring or tube well, but as soon as it comes in contact with air develops a whitish haze which on longer standing turns yellowish and then forms yellowish to reddish-brown deposits of hydrated ferric oxide, some of this deposit sticks to the side of the vessel and rest sinks to the filter bed Oxidation of ferrous bicarbonate is usually accomplished by the dissolved oxygen introduce into the water by aeration. Water directly from boring or tube well is first passed into the aeration chamber which is packed with manganese base catalyst. Before entering into the aeration chamber air is injected with water from an air compressor. Here according to the above reaction iron is oxidized into ferric form. Water is then passed through the iron removal filter which is packed with catalytic filtering media. Here residual ferrous iron is oxidized into ferric and retire precipitated ferric hydroxide is filtered out. The precipitated and entrapped ferric hydroxide is then removed from the filter bed during back washing. Capacity 50 to 50000 gallon per hour and above.
