We Ion Water Machineries pioneer in the field of Iron Removal Plants and Filters manufacturer, seller and supplier since 1967 in West Bengal. Raw water generally contains soluble iron in form of ferrous bicarbonate and insoluble as ferric hydroxide. The ferrous bicarbonate is clear when from a tube well, but as soon as it comes in contact with air develops a yellowish haze which longer standing turns reddish - brown deposits of ferric oxide, some of this deposit sticks to the side of the container and the rest sinks to the bottom. The raw water passed through a iron removal plant which packed with our own make patented oxidizing catalytic filtering media, here the residual ferrous iron is oxidized into ferric form and entire precipitated ferric hydroxide is filtered out. the precipitated and entrapped ferric hydroxide is then removed from the filter bed during the normal back washing. Capacity 50 to 50000 gallon per hour and above.
