Demineralization or D.M. plants help to remove dissolved minerals from
water to make it suitable for industrial and municipal use. In exchange
and electrically driven membrane are the major methods for deionizing
water. The process involves purifying water by filtering it through a
tank containing beads of synthetic resin. These beads are chemically
treated to either absorb negatively charged anions or positively charged
cations.Types of Demineralizers
- Membrane Demineralizers : This system uses physical separation
and in certain cases, electrical energy, to manufacture purified
water. Reverse osmosis is the most common form of this process,
producing pure water by passing it under pressure through a semi
permeable membrane.
- Mobile Demineralizers : This system is used for final polishing of
water, treated by Reverse osmosis.
- Mixed Bed Demineralization : This system allows anion and cation resins to be blended into a single tank or vessel. This system produces higher higher quality of water and is often used as a post treatment for Reverse Osmosis.
