Ion exchange is a purification process whereby ions are exchanged between a solution and an ion exchange resin ( either cationic or anionic). This is a process that can be reversed and the resin can be regenerated for re-use.
Common applications of ion exchange include the demineralisation and deionisation of process and boiler feed-water and the production of pharmaceutical water. In the preparation of potable and process water, de-carbonation and softening are commonly used. With specialist ion exchange resins, applications such as metals recovery, arsenic removal and heavy metal removal are also possible.
A typical example of application is the preparation of high-purity water for power engineering, electronic and nuclear industries Purified water or technically pure water, is indispensable for the pharmaceutical industry, for laboratories and for various industrial production processes. Purified water ( unlike drinking water) is totally free of additives, including minerals, calcium and other impurities.
While not suitable to drink, it’s a key component in producing medicines, microelectronics, glass and beverages. High-quality purified water is used for cleaning and rinsing, particularly in laboratories, and also as a solvent and carrier medium. At BWT, we supply the right treatment solution for every requirement of BWT Purified Water, depending on the specific application.
