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.
