We Ion Water Machineries manufacturer and supplier of iron removal plant in west bengal since 1967. The iron removal plant and removal the iron in raw water. Raw water generally contains soluble iron in form of ferrous bicarbonate and insoluble iron as ferric hydroxide. Water containing ferrous bicarbonate is clear when drawn from a tube well. But as soon asit 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 container and the rest sinks to the bottom. Oxidation of ferrous bicarbonate is usually accomplished by the dissolved oxygen introduce into the water by aeration as per following reaction:- 2Fe (HCO3)2+1/2 O2 + H2O > 2 Fe (OH)3 + 4CO2 Ferrous Oxygen Water Ferric Carbon Bicarbonate Hydroxide Dioxide
