Construction of Demineralization (DM) Treatment Plants
When it comes to industrial water treatment, demineralization plays a crucial role by effectively eliminating all dissolved solids and minerals from the feedwater. This process is particularly important for deaerated water used in boilers to generate steam, as well as for various process streams.
How does DM work?
This water treatment facility operates based on the ion exchange principle. It utilizes specially manufactured ion exchange resins to effectively eliminate mineral salts from the water. The plant employs two types of resins: anion and cation. Anion resins release negatively charged hydroxyl ions, while cation resins release positively charged hydrogen ions.
By utilizing cation-exchange resins, water softening can be achieved, while anion-exchange resins effectively remove nitrates from wastewater. Combining both methods through deionization can effectively eliminate virtually all ionic contaminants present in the feed water, resulting in exceptional water quality.
Applications
Demineralization is particularly useful in industries that require high-purity water, such as the production of electronics, food and beverage, and high-pressure boiler systems. It is also commonly utilized in industries that require steam, power, and cooling.
