FRP IRON REMOVAL

	IRON REMOVAL UNITS Iron Removal Filter (Water Treatment plants)
We have carved out a position in manufacturing and supplying a wide range of highly efficient Iron Removal Filters (Water Treatment Plants). These are widely used in various industries to remove dissolved iron from water and have gained skyrocketing popularity in the market for their high performance and longer service life. The entire range is manufactured using high grade factor inputs and sophisticated technologies in order ensure quality and high performance. Furthermore, these treatment plants can also be customized with the help of our vendors in accordance with clients’ specifications and requirements. In additions, Raw water generally contains soluble iron in form of ferrous bicarbonate and in soluble as ferric hydroxide. The 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 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 introduced into the water by aeration as per following reaction. 2Fe(HCO3)2            + 1/2 O2    + H2O 2Fe(OH)3             + 4CO2 Ferrous bicarbonate Oxygen Water             ferric Hydroxide Carbon Dioxide From the above reaction it appears that 1ppm of dissolved oxygen oxidizes 7ppm of ferrous iron as Fe. As solubility of oxygen from air dissolved in water at 600 F is 10ppm. Theoretically water saturated with dissolved air contains enough oxygen to oxidize 70ppm of ferrous iron. Process: ·                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 water from an Air Compressor. ·                According to the above reaction iron is oxidized into ferric form water is then passed through the Iron Removal Filter 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.
