1. Characteristics of continuous ion exchange
1) Due to continuous operation, the product composition and concentration after adsorption or ion exchange remain stable.
2) Because of continuous production, regeneration does not require repeated equipment, nor does it need to stop running. At the same time, the investment cost is low and the maintenance is simple.
3) Compared with the fixed bed system, the amount of resin can be reduced by 50-90%, and the amount of washing water can be saved by 50-70%.
4) At the same time, substances with different characteristics can be removed or separated, so the complicated process can be simplified.
5) Due to the compactness of the equipment, it is easy to install in any position, and it is easy to match with the original production process and equipment.
2. Application fields of continuous ion exchange
1) Food and beverage: decolorization and desalination of sugar; deashing and refining of fruit juice, D-ribose, sorbitol, etc.
2) Wastewater treatment: such as recovery of ammonium chloride in waste liquid, treatment of salicylic acid production wastewater
3) Metallurgy and materials: such as copper recovery from leachate, potassium extraction from seawater, precious metal recovery, etc.
4) Biochemical and pharmaceutical industries: extraction, separation, purification and concentration of antibiotics, vitamins, amino acids, Chinese herbal medicines, and plant active ingredients
