Standard work flow of softened water equipment

Due to the needs of reagent work, the standard workflow of softened water equipment mainly includes five processes: work (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. All the processes of different softened water equipment are very close, but due to the difference of the actual process or the need for control, there may be some additional processes. Any water softening equipment based on sodium ion exchange is developed on the basis of these five processes (among which, the fully automatic softening water equipment will increase the brine re-injection process).

Backwash:

After working for a period of time, the equipment will intercept a lot of dirt brought by the raw water on the upper part of the resin. After these dirts are removed, the ion exchange resin can be completely exposed, and the regeneration effect can be guaranteed. The backwash process is that water flows in from the bottom of the resin and flows out from the top, so that the dirt intercepted by the top can be washed away. This process generally takes about 5-15 minutes.

Salt absorption (regeneration):

In the process of injecting brine into the resin tank, the traditional equipment uses a salt pump to inject the brine, and the fully automatic equipment uses a special built-in injector to inhale the brine (the water must have a certain pressure). In the actual working process, the regeneration effect of brine flowing through the resin at a slower speed is better than that of simply soaking the resin with brine. Therefore, the softening water equipment is regenerated by the method of brine flowing through the resin at a slow speed. This qualified process is generally It takes about 30 minutes, the actual time is affected by the amount of salt used.

Slow flush (displacement):

After the brine flows through the resin layer, the process of slowly rinsing all the salt in the resin with raw water at the same flow rate is called slow rinsing, because there are still a large number of calcium and magnesium ions on the functional gene group in this process. Exchange, according to actual experience, this process is the main process of regeneration, so many people call this process replacement. This process is generally the same as the salt absorption time, that is, about 30 minutes.

Quick rinse:

In order to thoroughly rinse the residual salt, the resin should be rinsed with raw water at a flow rate close to the actual work. The final effluent of this process should be soft water that meets the standard. Under normal circumstances, the fast flushing process is 5-15 minutes.
