What is Demineralization?

Demineralization (DM) systems are a form of chemical water treatment that uses an ion exchange process to remove minerals and salts from water to produce pure water. The treated produced water can be completely free or almost free of dissolved minerals.

Throughout the demineralization process, strong acid cation resins in the form of hydrogen convert dissolved salts into the corresponding acids, while strong base anion resins in the form of hydroxides remove these acids.

How does Demineralization System Work?

The demineralization water plant works by removing dissolved minerals through an ion exchange process. The raw water passes through two small beds filled with polystyrene beads. In the first bed, a cation-hydrogen ion replacement reaction will occur.

In the second bed, anions will undergo a replacement reaction with hydroxyl ions. The hydrogen ions neutralize the hydroxyl ions, resulting in pure water. The system is equipped with a highly efficient ion exchange resin column, and a degassing system to eliminate minerals.

Demineralized water, Deionized water, Distilled water - What's the Difference?

Demineralized water, deionized water and distilled water are treated and have high quality. They can be used in electronics and chemicals, food and beverages, biopharmaceuticals, cosmetics and laboratories.

Demineralized water: Demineralization systems, like deionization systems, use an ion exchange process to remove virtually all dissolved solids from the raw water. Demineralized water removes essentially all minerals from natural water, such as calcium, magnesium, and many other minerals.

Deionized water: Obtained by removing ionic salts from water using ion exchange resins. There is also another form that works using electricity and semi-permeable ion exchange membranes called electrodeionization. Deionized water contains fewer mineral ions, ionic salts, etc.

Distilled water: The principle of distillation is to heat a liquid to boiling, then cool the water vapor, and finally collect the purified liquid water (i.e. distilled water) in a sterile container. This process removes almost all ionic, inorganic and biological contaminants from the water, so there are relatively few organic contaminants in distilled water.

Why Choose a Demineralization Water Plant?

Considering a large amount of energy required to heat, circulate and cool the distillation process, this can add high operating costs to a project.

Demineralization (DM) and deionization (DI) systems typically require only one drive pump to provide energy for circulating water and some of the chemical costs for resin regeneration, so energy costs are minimized and are more cost-effective than distillation, saving money for the project.
