We Ion Water Machineries manufacturer and supplier of iron removal plant in Kolkata, West Bengal and others cities of all over India. The iron removal plants remove iron and turbidity in raw water. In iron removal system ferrous iron is oxidized into ferric form and precipitated ferric hydroxide is entraped inside the bed. During the period of back washing suspended matters and precipitated iron come out of the plant. The plants do not require any regeneration. But chemical dosers like Alum Doser etc. are installed before plants. This is because of coagulating effect inside the plant. The plants are normally back washed when Gauges indicate pressure drop between 5 to 8 psig.
