Ion-Exchange Resins 25–37 L

Purifying compounds in water treatment are essential. There are several types of filtration materials, including resins, that ensure efficient filtration and pose no health risks. Ecosoft offers high-quality cation and anion ion-exchange resins for industrial demineralisation and softening applications. You can choose and buy a suitable product in our online shop at a reasonable price.

Ion-exchange resin is used in filtration technology for liquids, such as water, among others. It suggests that small, insoluble polymer beads (resin) are used. These porous beads hold harmless positively or negatively charged ions, H+ and OH-, to replace calcium, magnesium, sodium, chloride, sulfate, and nitrate in the water. The resin does not adversely affect taste, smell, and though the ions attached to it chemically react, their functional groups are considered safe. They are neither toxic nor reactive. As a result, contaminants and salts are effectively removed from the water, leaving it tasty, soft, and safe to drink. Treated water is not only used for domestic needs to drink, cook, and prepare beverages. It is used across different industries, like food processing, power generation, chemistry, healthcare, bioenergy, and other sectors.

Ion-exchange resin removes undesirable ions of heavy metals and those minerals that cause hardness by replacing them with safe sodium or hydrogen. The harmful ions just stick to the resin beads and stay there. Such water purification softens and demineralises water, which protects water consumers from severe, long-term detrimental effects of hard metals and plumbing systems and other appliances from lime.

When there are too many harmful ions and too few sodium or hydrogen ions, the filter, or we’d say that it is the treatment medium, should be recharged. It is crucial to properly maintain resins and timely renew the filtration material when its service life is exhausted. Regeneration is performed according to the type of resin. A brine solution (to wash off calcium and magnesium) or specific acids (to clean cation resin) are used. The lifespan depends on applications, water quality, and other factors. It can be about 3 years or longer.

There are two main types of ion-exchange resins:

• Cation. Negative beads hold positive ions, the so-called cations, which are named sodium and hydrogen ions. They are used to trap calcium and magnesium and replace them with sodium to soften water.
• Anion. Positive beads hold negative ions, the so-called anions, which are mainly hydroxide ions, consisting of an oxygen atom and a hydrogen atom. They remove negatively charged ions, like sulfates and chlorides.

There are also specialised ion-exchange resins that remove toxic heavy metals from drinking water. The application is mentioned in the product description. In our shop, you can order the mixed bed ion exchange resin from Pure Resin Company Limited. Its functional groups are cation (RSO₃-H⁺) and anion (R₄N+OH^-).

Ready-to-use ion-exchange resin is a highly efficient, trusted solution. It can be applied as a tap and well water filter and used in advanced household water filters. Its general benefits are as follows:

• a highly stable performance and high endurance;
• numerous full regeneration cycles;
• both softening and demineralisation applications;
• easy maintenance compared to other drinking water filters;
• a long service life in both industrial and residential water treatment systems.

This technology delivers treated water of consistently high quality. We also have Pure PC003UN Gel, a strong acid cation exchange resin that comes with NSF/ANSI 44 & 61 certification for drinking water applications. There are products with high-temperature stability (DuPont™ AmberLite™ HPR1200 NA).

Ion-exchange resins, which you can find in our catalogue, meet strict international standards and are compatible with Ecosoft water softeners and filters. We also offer patented multi-component ECOMIX media from Ecosoft to treat water with high levels of organic matter. To purify water from bacteria and viruses, in addition to other contaminants, consider reverse osmosis filters.
