Softened water equipment workflow
Work (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow flushing (replacement), and quick flushing. All processes for different softened water plants are very close, but there may be additional processes due to actual process variations or control needs. Any softened water equipment based on sodium ion exchange is developed on the basis of these five processes (where fully automatic softened water equipment increases the brine refilling process).
The working process of the softened water equipment is backwashed:
The equipment after working for a period of time will intercept a lot of dirt brought by the raw water in the upper part of the resin. After the dirt is removed, the ion exchange resin can be completely exposed, and the regeneration effect can be obtained. Guarantee. The backwashing process is that water is washed 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 usually takes about 5-15 minutes.
Salt absorption (regeneration):
The process of injecting salt water into the resin tank. The traditional equipment uses a salt pump to inject the brine. The fully automatic equipment uses a special built-in injector to suck the salt water (as long as the water has a certain pressure) . In the actual working process, the regeneration effect of the brine flowing through the resin at a slower speed is better than that of simply impregnating the resin with salt water. Therefore, the softened water equipment is regenerated by slowly flowing the salt water through the resin. This process generally requires 30. In minutes or so, the actual time is affected by the amount of salt used.
Slow rinsing (replacement):
After flowing the resin through the brine, the process of rinsing all the salt in the resin at the same flow rate with raw water is called slow rinsing, because there are still a large number of functional groups in this rinsing process. Calcium and magnesium ions are exchanged by sodium ions. According to practical experience, this process is the main process of regeneration, so many people call this process a replacement. This process is generally the same as the time of salt absorption, ie about 30 minutes.
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 the soft water up to standard. In general, the fast rinse process is 5-15 minutes.
