We ION Water Machineries, one of the pioneer in water treatment in Kolkata, West Bengal, We are water treatment Plant manufacturer and supplier since 1967. We are also mnfgr of D.M. Plant. ION EXCHANGE is one of the most important tools in Chemical Engineering process, such as Preparation, Purification, Separation of different type of inorganic and organic compounds, Solvents, etc. One of the most important applications of the process of Ion Exchange is to produce best quality of distilled water in low cost. The reason in favour of Demineraliser is that the D, M, Water in comparison with the distilled water is much better in quality and cheaper in prices. Operation is simple. Cost of production is negligible. Operation is very simple without Heat and Electricity. Guaranteed Specified Water quality conforms to Purified Water as per I.P.
