Demineralization Plant

Demineralization, also known as Demineralization, is the process of removing dissolved minerals from water to make it suitable for industrial or municipal use Resin-based demineralization systems are typically designed in two-bed delonizers, the anion and cation resins are blended into a single tank or vessel. Generally, mixed-bed systems will produce higher quality water with a lower total capacity the two-bed systems. They are often used as post treatment for reverse osmosis (RO) plant for final polishing of the water to high purity.
Usually a mixed bed-polishing unit contains strong acid cation (SAC) resins and strong base anion (SBA) resins combined to a ratio of approximately 40% cation resins to 60% Anion resins. (All resin volumes are dependent upon the incoming water analysis and the required quantity of treated water).
