THE CHALLENGE
High levels of contaminants in the raw water need to be removed before being used as drinking/tap water or for food processing. Ion exchange resins are widely used to remove/reduce the hazardous contaminants at the entry (Point-of-entry) or at the end, were the water is used (Point-of-use).

Applications and Solutions for Drinking Water

Ion exchange resins are used to remove hazardous contaminants from drinking water and are especially effective when used in consumer POE/POU water treatment systems.

Purification is the key application for ion exchange resins. The resin beads purify several different streams like water, chemical, sugar, juice, pharmaceuticals, proteins, and much more. IX resins can selectively remove contaminants from gold to perchlorate. There are endless possibilities for purifying any type of stream with IX technologies.

Demineralisation is the process of removing virtually all dissolved solids (TDS) from water and producing essentially pure water. Demineralisation unit must include both cation and anion exchange processes. Mixed bed demineralisation consists of strong acid cation resin and strong base anion resin which are mixed homogeneously when in service. Boiler makeup water, process water for production operations and high purity rinse water are examples that require demineralised water.
