The difference between mixed bed resin and anion cation resin

Mixed bed resin and anion cation resin are two different types of ion exchange resins. Mixed bed resin is a type of resin that has both anion and cation exchange capabilities. In contrast, two types of resins with anion and cation exchange functions, respectively, are packed in different columns.

Differences in processing power

The mixed bed resin has a small exchange capacity and is suitable for treating water with energy and anions present simultaneously, such as twisted membrane purified water and softened water. Relatively speaking, the exchange capacity of anion and cation resins is larger, and they have a wider range of applications, which can treat various types of water and wastewater. In addition, anion and cation resins can also be used to separate mixtures and purify chemicals.

Differences in composition and use

Mixed bed resin: a product made by mixing anionic resin and cationic resin simultaneously, which can simultaneously remove anions and cations from water. Suitable for pure water treatment and high-purity water production processes to achieve extremely high water quality requirements. It is usually used for the final stage of ion exchange to remove residual ions and dissolved substances in water and obtain pure water.

Yin Yang resin: There are two different resins with anion selectivity and cation selectivity, for example, anion resin can selectively remove anions from water, and cation resin can selectively remove cations from water. Suitable for the separation and removal of specific ions in water, it can be used alone or in combination as needed in the water treatment process, and can be used for softening water, salt, color, iron, manganese and other application fields.

How to choose between them?

Therefore, when choosing ion exchange resins, careful consideration should be given to different practical applications. If there are only anions or cations in the water to be treated, a single anionic or cationic resin can be chosen. If the water contains both anions and cations and needs to be treated simultaneously, choosing a mixed bed resin is a good choice. If it is necessary to treat wastewater or purify chemicals, anion cation resin can be chosen.

Overall, mixed bed resin and cation exchange resin are two types of ion exchange resins, and their main differences lie in their selectivity towards ions and treatment methods. This means that mixed bed resins are generally used alone, while anionic and cationic resins have selectivity for anions and cations, and can be used alone or in combination as needed, mainly to remove and separate specific ions.
