What is a DM Water Plant?
A DM Water Plant, also known as a Demineralization Plant or Demineralized Water Treatment Plant, is a water purification system designed to remove dissolved ionic impurities from water.
The system generally uses ion exchange technology, where unwanted cations and anions are exchanged with hydrogen and hydroxyl ions. These ions combine to form water, resulting in low-mineral-content treated water
How Does a DM Water Plant Work?
Pretreatment
Raw water is first treated to remove suspended particles, turbidity, and other impurities that could affect the ion exchange process.
Cation Exchange
The water passes through a cation exchange resin. Positively charged ions such as calcium, magnesium, and sodium are exchanged with hydrogen ions.
Anion Exchange
The water then passes through an anion exchange resin, which removes negatively charged ions such as chloride, sulphate, bicarbonate, and other anions.
Degassing
In some DM systems, a degasser is used to remove dissolved gases such as carbon dioxide from the treated water.
Polishing
For applications requiring very high water purity, a mixed-bed unit may be used as a final polishing stage.
DM Water Storage
The treated demineralized water is collected in a suitable storage tank and supplied to the required industrial application.
