Hydrosoft DM Plant

The ion exchange technique is used to remove mineral salts from water during demineralization Demineralized water is water that has been stripped of all dissolved minerals (or nearly so) as a result of one of the following processes:

Distillation is the process of extracting alcohol from water.

Deionization is the process of removing a substance from

Filtration using membranes (reverse osmosis or nanofiltration)

Other technologies, such as electrodialysis

Water that has had its mineral ions removed, also known as Demineralized Water or Deionized Water. Mineral ions such as sodium, calcium, iron, copper, and others, as well as anions such as chloride, sulfate, and nitrate, are common ions found in water.

The DM plant is divided into two beds (Cation & Anion). Two Bed Outlet water quality (conductivity) will be between 25 and 30 micro siemens. Raw water is first put through a cation resins column (H+ form), which transforms all ionized salts to their mineral acid equivalents. Then there's the Anion Resins Column (OH form), which absorbs these acids and produces Deionized (Demineralized) water. When the resins are depleted, the cations are regenerated with hydrochloric acid (HCl), while the anion resins are renewed with a solution of caustic soda (NaOH). As a result, the same resins can be used to make DM water over and over again.

THE PROCEDURE

Ion-exchange, in the context of water purification, is a quick and reversible process in which contaminant ions in the water are replaced by ions released by an ion-exchange resin. The impurity ions are collected by the resin, which must be recycled on a regular basis to return to its original ionic state. (An ion is an electric-charged atom or group of atoms.) Cations are positively charged ions that are usually metals; anions are carbon dioxide and water that are usually non-metals).
