The principle and application of ion exchanger


The softener is a sodium ion exchanger, and the ion exchanger is divided into: sodium ion exchanger, yin and yang bed, mixed bed and other types, mainly used in boilers, thermal power stations, chemical industry, light industry, textile, medicine, biology, electronics, atomic energy It can also be used for the decolorization and purification of food and medicine, the recovery of precious metals and chemical raw materials, and the treatment of electroplating wastewater. The mixed bed is to fill the anion and cation exchange resins in the same ion exchanger according to a certain mixing ratio. Since the H ions and OH ions entering the water after the mixed ion exchange immediately generate water molecules with a very low ionization degree, the exchange reaction can be carried out smoothly. Very thorough. The mixed bed is generally installed after the first-level complex bed for further purification of water quality.

It can also be used alone when the water quality requirement is not high. Sodium ion exchanger or softener is an ion exchanger used to remove calcium ions and magnesium ions in water to produce softened water. The calcium and magnesium ions that make up the hardness in the water are exchanged with the ion exchange resin in the softener, and the calcium and magnesium ions in the water are exchanged with sodium ions, making it difficult to form carbonate scale and sulfate scale in the water, thus obtaining softened water.

The plexiglass ion exchange device is corrosion-resistant, colorless and transparent, and is suitable for small-scale pure water preparation in food, medicine, sugar and electronics industries. The carbon steel rubber-lined ion exchange device has the characteristics of large water production capacity, high strength, and low cost. It is suitable for large-scale boiler demineralized water and large-scale pure water preparation. Purified water is ordinary water that undergoes electrodialysis, which greatly reduces the original mineral content in the water, and at the same time disinfects and sterilizes it. Such water becomes "pure water".

The electrodialysis project is one of the separation projects using membrane methods. Its principle is to use ions to migrate through the selective ion exchange membrane under the action of a direct current electric field to partially separate the electrolyte ions from the solution. Main purposes: 1. Production of pure water 2. Seawater desalination, brackish water desalination 3. Fluoride removal, waste water treatment 4. Power equipment water supply desalination Poolking is the best swimming pool equipment manufacturer and supplier in China.
