| Demineralizer These are the water treatment plants where the raw water having high concentration of total dissolved solids is passed through a hydrogen based cation resin bed where all the positive ions in water are replaced with hydrogen ions from the resin and water coming out of it is free from positive ions. Partially treated water from cation is then passed through a hydroxyl based anion resin where all the negative ions of water are replaced with hydroxyl ions of resin bed and water coming out of it is free from unwanted negative ions. Treated water from cation and anion resin bed is of very high purity with zero hardness and negligible total dissolved solids. Demineralizers find their application in various industries such as textile, food, fine chemicals, electroplating and pharmaceuticals. |
