Ion exchange(IX) resins are made up of a highly porous, polymeric material that is acid, base and water insoluble. The beads that make up these resins are derived from hydrocarbon and are about ½ millimeter in diameter.
There are two main types of resins used for IX: anion and cation.
Anion resins and cation resins are the two most common resins used in the IX process. The difference between anion and cation resins is that one is positively charged and the other is negatively charged.
Negatively charged ions are attracted to positively charged anion vs. cation resins, which attract positive ions with their negative charge. There are a number of physical and chemical properties to take into consideration when selecting a resin, and which will help to determine the best resin for your needs, such as:
The size of the ion exchange resin beads.
The amount of water it can hold.
The amount of ions it can filter out before needing to be regenerated.
The rate at which resin allows water to flow through it.
The desired quality of the final effluent water.
The type and amount of contaminants in the source water.
This products are treated such that they contain thousands of tiny cracks, thus increasing their surface area. As source water passes through the products, molecules with minerals are left “clinging” to the many surfaces of the beads. This continues until all the beads are covered in minerals, at which time, the resin must be regenerated, which will flush the minerals out, and return the resin to like-new condition.
