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.
Control modes of automatic water softeners:
(1) Single tank time type: the time control of microcomputer is used, so that the equipment is able to automatically enter into the regeneration state after running for a set period of time. The regeneration can be once a day or repeated every day.
(2) Single tank flow type: the turbine flow control or electronic flow sensor control is used, so that the equipment is able to automatically enter into the regeneration state when its water yield reaches a pre-set flow. The regeneration can be repeated every day.
(3) Dual-tank flow type: it can be divided into Mode? I with one tank for use and the other for standby and Model llwith two tanks for simultaneous operation and respective regeneration.
Model l: one tank runs and the other one stands by. The running tank enters into the regeneration state after its water outflow reaches a set flow and at the same time the standby tank starts running, two tanks running and regenerating alternatively for continuous *4 hours’ water supply.
Model II: two tanks run simultaneously. The first tank continuously produces water while the second tank regenerates first and restarts running after regeneration, and then the first tank starts regeneration. After both tanks finish regeneration, they run simultaneously again.
