As the science advances with high pressure boilers at super thermal power station, manufacturing of silicon chips for computers and electronic applications, pharmaceuticals, Atomic Power Plants and many more industries where stringent specifications are applied. At all such places high purity water is required.
To produce high purity water of the desire specifications the ion exchanged resin based demineralizers are the first choice of the entrepreneur.
Generally, the raw water is passed through cation exchangers followed by anion exchangers to get pure water.
The cation exchanger removes / replaces most of the positive ions while anion exchangers removes/replaces all most all negative ions detected by normal water analysis methods.
The outlet of anion exchange is a desired quality water.
