Sodium ion exchanger:
What is the principle of sodium ion exchanger?
The hardness of water is mainly composed of calcium and magnesium ions. When the raw water containing hardness passes through the resin layer in the softener, the calcium and magnesium ions in the water are adsorbed by the resin, and the sodium ions are released at the same time. The water flowing out of the softener is the softened water that removes the hardness of the ions.
When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated, the regeneration process is to use the brine in the salt water rinse the resin layer, the resin on the hardness of the ions and then replaced, with the regeneration of waste discharged from the tank, the resin But also restored the ability to soften the exchange.
What are the classification of sodium ion exchangers?
According to the way of operation points: fixed bed, continuous exchange bed, floating bed.
Which fixed bed can be divided into: downstream regeneration fixed bed, countercurrent regeneration fixed bed. Continuous exchange bed can be divided into: moving bed, fluid bed.
According to the ion exchange water, regeneration, washing water flow control points: integrated valve control form and discrete multi-valve control shape.
Sodium ion exchanger applications:
High hardness of drinking water softening, softening of raw water, raw water drinking water pretreatment, boiler water and various types of heat exchanger to add water softening, and air conditioning system cooling water softening treatment.
