The standard working process of fully automatic water softening equipment mainly includes five steps: working (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow rinsing (replacement), and fast rinsing.

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 which, fully automatic water softening equipment will add a brine recharging process).

Backwashing of fully automatic water softening equipment: After working for a period of time, the softening 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 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.

Fully automatic water softening equipment salt suction (regeneration) : This is the process of injecting brine into the resin tank. Traditional equipment uses a salt pump to inject brine, while fully automatic equipment uses a dedicated built-in injector to draw in brine (as long as there is a certain pressure in the incoming water). In the actual operation of fully automatic water softening equipment, the regeneration effect of salt water flowing slowly through the resin is better than that of simply soaking the resin in salt water. Therefore, deionized water 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.

Slow flushing (replacement) of fully automatic water softening equipment 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.

Rapid flushing of fully automatic water softening equipment: To thoroughly wash away the remaining salt, the resin should be flushed with raw water at a flow rate close to the actual working condition. The effluent from this process should be qualified softened water. Under normal circumstances, the quick flushing process of water softening equipment is5-15Minutes.
