1Work(Sometimes it is called water production, the same below)Backwashing, salt absorption(Regeneration)Slow rinse(Replacement)Five processes of quick rinse. All the processes of different water softening equipment are very similar. However, due to the differences in actual processes or control requirements, there may be some additional procedures. Any water softening equipment based on sodium ion exchange is developed on the basis of these five processes(Among them, the fully automatic water softening equipment will add a brine recharging process).

2BackwashingAfter working for a period of time, the equipment will intercept a lot of impurities brought by the raw water on the upper part of the resin. Only after removing these impurities can the ion exchange resin be fully exposed and the regeneration effect be guaranteed. The backwashing process involves water being washed in from the bottom of the resin and flowing out from the top, which can wash away the dirt trapped at the top. This process usually requires5-15About a minute.

3Salt absorption(Regeneration)The process of injecting brine into the resin tank is that traditional equipment uses a salt pump to inject brine, while fully automatic equipment uses a dedicated built-in injector to draw in the brine(As long as there is a certain pressure in the incoming water, that's it Can be). In the actual working process, the regeneration effect of salt water flowing slowly through the resin is better than that of simply soaking the resin in salt water. Therefore, water softening equipment all adopt the method of salt water flowing slowly through the resin for regeneration. This process generally requires30It takes about minutes, but the actual time is affected by the amount of salt used.

4Slow rinse(Replacement):After the salt water flows through the resin, the process of slowly rinsing all the salt in the resin with the original water at the same flow rate is called slow rinsing. Since a large number of calcium and magnesium ions on the functional groups are still exchanged with sodium ions during this rinsing process, based on practical experience, this process is the main process of regeneration, so many people call this process displacement. This process usually takes the same amount of time as salt absorption, that is30About a minute.

5Quick rinseTo thoroughly rinse off the remaining salt, the resin should be flushed with raw water at a flow rate close to the actual working condition. The final effluent of this process should be qualified soft water. Under normal circumstances, the quick rinse process is5-15Minutes.
