Boiler soft water equipment is mainly used for industrial and civil softening water preparation, such as boiler feed water, air conditioning system supplement water, heat exchanger, desalination, high purity water preparation, industrial wastewater treatment, heavy metal and metal recovery, etc. Pretreatment of electronics, power plants, chemicals, metallurgy, environmental protection, biology, medicine, food, light industry, textile biopharmaceuticals, electronics and pure water systems.
The hardness of water is mainly composed of cations: calcium (Ca2+) and magnesium (Mg2+) ions. When the raw water containing hardness ions passes through the exchanger resin layer, the calcium and magnesium ions in the water are replaced with the sodium ions in the resin, and the resin adsorbs calcium and magnesium ions and the sodium ions enter the water, so that the water flowing out of the exchanger is The softened water of the hardness ions is removed. As the exchange process continues, the Na+ is completely removed from the resin and the exchange function is lost. At this time, the resin must be regenerated with Nacl solution, the Ca2+ and Mg2+ adsorbed by the resin are replaced, and the resin re-adsorbs the sodium ion. When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to rinse the resin layer with the brine in the salt tank, and the hardness ions on the resin are replaced, and the resin is discharged with the recycled waste liquid. The softening exchange function is restored.
