WHAT ARE THE EFFECTS IF THE SODIUM SLIP IS HIGH IN DM WATER
11-05-2017, 10:01 AM
The process used for the removal of all dissolved salts from the water is known as deionization. Deionization requires the flow of water through two ion exchange materials in order to effect removal of the entire salt content.
Deionization The terms demineralization and deionization are used interchangeably by industry. Although the term demineralization is generally better understood, deionization is especially apt.
Demineralization (DM) Water Treatment Plants
Demineralization is the process of removing mineral salts from water by using the ion exchange process.
Demineralized water is completely (or nearly) completely free water from dissolved minerals as a result of one of the following processes:
• Distillation
• Deionization
• Membrane filtration (reverse osmosis or nanofiltration)
• Electrodialysis
• Or other technologies.
Demineralized Water also known as Deionized Water, water that has had its mineral ions removed. Mineral ions such as sodium, calcium, iron, copper, etc. cations and anions such as chloride, sulfate, nitrate, etc. are common ions present in the water. Deionization is a physical process using specially manufactured ion exchange resins that provide an ion exchange site to replace the mineral salts in water with water forming H + and OH- ions. Because most water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is fast and without buildup of scale. Demineralization technology is the proven process for water treatment. A DM water system produces mineral free water operating on the principles of ion exchange, degassing and polishing. The Demineralized Water System finds extensive application in the field of steam, power, process and cooling.
Principle
The raw water is passed through two beds of small filled polystyrene (ion exchange resins). While the cations are exchanged with hydrogen ions in the first bed, the anions are exchanged with hydroxyl ions, in the second.
Process
In the context of water purification, ion exchange is a rapid and reversible process in which the ions of impurity present in the water are replaced by ions released by an ion exchange resin. The impurity ions are absorbed by the resin, which must be regenerated periodically to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Positively charged ion are called cations and are generally metals, negatively charged ions are called anions and are generally non-metals).
