Full Automatic Water Softener Water Purification for Housing

Working principle
To absorb the calcium and magnesium ions in the water with resin-As the hardness of the water is mainly formed and expressed by calcium and magnesium, the cation exchange resin (water softener)is generally used to replaceCa2 + and Mg2in the water The resin efficiency to removeca2 + and Mg2+ gradually reduces as ca2 + and Mg2 + in the resin increase. When the resin absorbs a certain amount of calcium and magnesium ions, it is necessary to be regenerated. In the regeneration process, the resin bed is flushed by saline in the salt box and hardness ions on the resin are replaced and discharged with recycled waste fluid, the resin's function of softening exchange is recovered. The principle of sodium ion exchanging softening treatment is to use sodium cation exchange resin to exchange the hardness ingredients, Ca2 + and Mg2 +, in the raw water with Na + in the resin, absorbing Ca2 + and Mg2 + in the water, so that water gets softened.

Working principle01. By means of Absorbing the calcium and magnesium ions in water with resin, since the hardness of water is mainly composed of calcium and magnesium, in general, we adopt cation exchange resin (softener), replace Ca2+, Mg2+ (main ingredients for scale) in water, as the increase of Ca2+ and Mg2+ in resin, removing performance on Ca2+, Mg2+ of resin will gradually reduce.
02. When the resin has absorbed a certain amount of calcium and magnesium ions, it must be regenerated, the regeneration process is that flush resin layer with the salt water in salt box, replace hardness ion out of the resin again, and discharged from the tank with waste liquid of regeneration, then resin resumed the function of softening and exchanging.
03. The principle of sodium ion exchange and softening treatment is to exchange cation in the raw water with resin, hardness constituents Ca2+and Mg2+ in water exchange Na+ in resin, thus absorb the Ca2+and Mg2+ to make the water to be softened.
2RNa + Ca2+ = R2Ca + 2Na+
2RNa + Mg2+ = R2Mg + 2Na+
After the water treated by sodium ion exchanger, the Ca+ and Mg+ were superseded by Na +.
Application scope of softener
Mainly used in industry and civil water softening preparation, such as Boiler feed water make-up water, air conditioning system make up water, heat exchanger, power plant, chemical, textile, printing and dyeing, bio-pharmaceutical, Electronic system and water pretreatment.
