Demineraliser

Demineraliser

A demineraliser is a system that removes dissolved ionic chemicals (salts) from water using an ion exchange chemical process. It is sometimes referred to as a Deionized Water System, a Demineraliser, or a DM Plant.

The demineralization plants are two-column systems in which the water passes through a cation exchange column first and then an anion. Water contains both positive and negative charged ions . Positive charged ions like calcium, magnesium, sodium, potassium etc. called cations. Negative charged ions like chloride, sulfate, carbonate, bicarbonate etc. called anions.

We design DM plant in various size & Shapes Manually Operated & Fully Operated as per customer requirement.

Process

Two Bed DM Plant

The pretreated water after passing membrane entered into Cation Vessel & then Anion Vessel.

This is a two-vessel process where one vessel contains cation resin and the other anion resin. Water first goes via a cation exchanger vessel where each cation is exchanged with an equal number of hydrogen ions. After that the water passes through anion exchanger vessel, here the same principle is applied and anions are exchanged with hydroxyl ions.

Uses of Demineralised Water

Demineralised water is utilized for different industrial operations because of its high level of quality. Water with a lower purity level might contaminate these processes. When water with a low salt content or insufficient conductivity is required, demineralised water is also utilized.
