DEMINERALISED PLANT (DM Plants) are designed based on the latest cost-effective ion exchange technique of counter-current regeneration. The units consist of two corrosion-free pressure vessels internally connected in series. The first column contains Cation absorbing exchanger and the second column is charged with an anion-absorbing exchanger. The water flow Passes through the bed of a Cation exchanger then the bed of an anion exchanger and the systems remove dissolved salts from water to a specified degree.

Regeneration requires after using total exchange capacity. The Cation Resin is regenerated with an acid and the anion resin is regenerated with an alkali solution. RWT consists of an acid/alkali proof pressure vessel with internal fittings and initial charge of Cation and Anion exchanger, set of regeneration equipment, hydraulic ejectors, acid and alkali tanks, and conductivity meter to monitor treated water quality. These DM Plants offer a practical range of capacities and flow rates necessary to serve a wide variety of applications.
