We ION WATER MACHINERIES pioneer in the field of Iron Removal Plant manufacturer and supplier in Kolkata since 1967. We are specialist in Iron Removal Manufacturing. Iron Removal Plant made by M.S. dished end vertical cylindrical shell provided with hand hole, charging hole etc. perforated bed support plate fitted with uniformly spaced special plastic strainers.
