DM water plant
Near-pure water for demanding processes
Some processes need water with almost no dissolved minerals at all. A demineralisation (DM) plant uses cation and anion ion-exchange resins to remove positively and negatively charged ions, producing water with extremely low conductivity.
For the highest purity, a mixed-bed polisher is added after the main units. We also design RO + DM combinations that reduce chemical consumption and running cost.
Industries that rely on DM water
- Power plants and high-pressure boilers
- Battery manufacturing
- Pharmaceuticals and laboratories
- Textile finishing, electronics and coatings
Why clients rely on us
Engineering you can depend on
Quality at every step
We select vessels, membranes, media and pumps that suit local water conditions, and we test the treated water before handover so you can see the result for yourself.
Modern treatment technology
RO, UF, ion exchange, multimedia filtration, UV and automated controls — we combine proven technologies into a plant that is efficient to run and simple to operate.

When ordinary treated water is not pure enough
Minerals that are harmless in drinking water can cause deposits, corrosion and product defects in industrial processes.
-
Boiler & turbine deposits
Silica and salts form hard deposits at high pressure.
-
Battery performance
Impurities in electrolyte water shorten battery life.
-
Lab & pharma accuracy
Dissolved ions interfere with tests and formulations.
-
Textile finishing
Minerals affect dye uptake and fabric quality.
-
Electronics & coating
Residues leave spots and defects on finished surfaces.
-
Corrosion
Dissolved salts accelerate corrosion in closed systems.
Treatment stages
How a DM plant works
A typical two-bed plant with optional polishing.
-
1
Pre-filtration
Sand and carbon filters protect the resin from solids and chlorine.
-
2
Cation exchanger
Removes calcium, magnesium and sodium ions.
-
3
Degasser (optional)
Strips carbon dioxide to reduce load on the anion unit.
-
4
Anion exchanger
Removes chloride, sulphate, nitrate and silica.
-
5
Mixed-bed polisher
Final polishing for ultra-low conductivity water.
-
6
Regeneration
Acid and caustic restore the resin when exhausted.

DM water plant — FAQ
What is the difference between DM and RO?
RO removes most dissolved salts using membranes, while DM removes almost all ions using ion-exchange resin. They are often combined: RO first, DM for final purity.
Which chemicals are used for regeneration?
Typically hydrochloric acid for the cation resin and caustic soda for the anion resin. We train your operators on safe handling.
How often is regeneration needed?
It depends on feed water TDS and daily volume. Conductivity monitoring shows exactly when a unit is exhausted.
Can you add RO to my existing DM plant?
Yes. Adding RO before an existing DM plant is one of the most effective ways to reduce chemical costs.
