We Ion Water Machineries manufacturer and supplier of iron removal plant and domestic online iron removing filter in West Bengal since 1967. Raw water generally contains soluble iron in form of ferrous bicarbonate and in soluble as ferric hydroxide. Water containing ferrous bicarbonate is clear when drawn from a tubewell, but as soon as it comes in contact with air develops a whitish haze, which is 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 container and rest sinks to the bottom oxidation of ferrous bicarbonate is usually accomplished by the dissolve oxygen introduce into the water by aeration. Water directly from the tube well is first passed into the aeration chamber Packed with manganese base catalyst. Before entering into the aeration chamber air is injected with the raw 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 plant packed with catalytic filtering media. Here the residual ferrous iron is oxidized into ferric and entire precipitated ferric hydroxide is filtered out. The precipitated and entrapped ferric hydroxide is then removed from the bed during back washing. Capacity 50 to 50000 gallon per hour and above.
