IRON REMOVAL PLANT Raw water generally contains soluble iron in from of ferrous bicarbonate and in soluble as ferric hydroxide. water containing ferrous bicarbonate is clear when drawn from a 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 yellow wish to reddish brown deposits of hydrated feric oxide, some of the deposite sticks to the side of the container and the rest sinks to the bottom Oxidation of ferrous bicarbonate is usually accomplished by the dissolved oxygen introduced ininto the water by aeration accomplished by the dissolved oxygen introduced in to the water by aeration water directly from the tube well is first passed into aeration chamber 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 feric from water is then passed through the iron removal filter packed with Catalytic Filtering media here the residual ferrous iron is oxidized into feric and entire precitated feric hydroxide is filtered out The precipatated and entraped feric hydroxide is then removed from the bed during back washing Capacity- 50-50, 000 Gallon per hours and above.
