Working Process
Product Water
Untreated raw water flows through the resin layer from top to bottom, and ion exchange reaction takes place to produce softened water, which is discharged from the soft nozzle.
Back Wash
After the resin fails, it needs to backwash first. Raw water flows through the resin layer from bottom to top, and backwash sewage is discharged from the drain outlet. The backwashing process can remove the suspended solids trapped in the resin layer, destroy the resin hardening, and loosen the resin so that the regenerated salt solution can be evenly distributed in the resin layer.
Regenerate
The saturated salt water in the salt tank is sucked into the raw water runoff by the salt suction valve to form the regenerated salt solution. Regenerated salt solution flows through the resin layer from bottom to top, that is, the exchange saturated resin is regenerated in the downstream, and the regenerated waste liquid is discharged from the drain outlet.
Rinsing
The raw water flows through the resin layer from top to bottom, so that the water can wash away the surplus salt liquid remaining in the regeneration, and the flushing sewage is discharged from the drain outlet.
Water Flooding
Inject water into the dissolved salt tank to dissolve salt crystals and form new saturated salt water for reuse next time.
Resin Replacement
If the regeneration frequency of the softener is too high or the hardness of the effluent cannot meet the requirements after regeneration, the softened resin has failed, and the softened resin needs to be replaced. The failure period of softened resin varies according to the hardness of raw water and the use frequency of softener, generally 2-3 years.
