Product details: Softening water treatment equipment refers to equipment that reduces water hardness, mainly removing calcium and magnesium ions from water. Simply put, it refers to equipment that reduces water hardness. Its main functions include removing calcium and magnesium ions from water, activating water quality, disinfecting algae, and preventing scale and scale removal.

1、 Working principle

Due to the fact that the hardness of water is mainly formed and represented by calcium and magnesium, cation exchange resins (water softeners) are generally used to replace Ca2+and Mg2+(the main components that form scale) in the water. As the Ca2+and Mg2+in the resin increase, the efficiency of the resin in removing Ca2+and Mg2+gradually decreases.

After a certain amount of calcium and magnesium ions are absorbed by the resin, regeneration must be carried out. The regeneration process involves washing the resin layer with salt water from the salt tank, replacing the hardness ions on the resin. As the regeneration waste liquid is discharged from the tank, the resin resumes its softening and exchange function.

Due to the fact that the hardness of water is mainly formed by calcium and magnesium, and the principle of sodium ion exchange softening treatment is to exchange the hardness components Ca2+and Mg2+in the water with Na+in the resin through a sodium type cation exchange resin, thereby adsorbing Ca2+and Mg2+in the water and softening the water.

3、 Workflow

There are five processes: work (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. All processes of different softened water equipment are very similar, but due to differences in actual processes or control needs, there may be some additional processes. Any softened water equipment based on sodium ion exchange has been developed on the basis of these five processes (among them, fully automatic softened water equipment will increase the process of brine reinjection).

(1) Backwashing: After working for a period of time, the equipment will intercept a lot of dirt brought by raw water on the upper part of the resin. After removing these dirt, the ion exchange resin can be fully exposed, and the regeneration effect can be guaranteed. The backwashing process involves water washing in from the bottom of the resin and flowing out from the top, which can flush away the dirt intercepted from the top. This process usually takes about 5 to 15 minutes.

(2) Salt absorption (regeneration): The process of injecting salt water into the resin tank. Traditional equipment uses a salt pump to inject salt water, while fully automatic equipment uses a dedicated built-in injector to suck in salt water (as long as there is a certain pressure in the inlet water). In actual work, the regeneration effect of saline water flowing through the resin at a slower speed is better than that of simply soaking the resin in saline water. Therefore, softened water equipment is regenerated using the method of saline water slowly flowing through the resin. This process generally takes about 30 minutes, and the actual time is affected by the amount of salt used.

(3) Slow flushing (replacement): After passing through the resin with saline water, the process of slowly flushing all the salts in the resin with raw water at the same flow rate is called slow flushing. Due to the fact that a large number of calcium and magnesium ions on functional groups are still exchanged by sodium ions during this flushing process, according to practical experience, this process is the main process of regeneration, so many people refer to this process as replacement. This process is generally the same as the salt absorption time, which is about 30 minutes.

(4) Quick flushing: In order to thoroughly rinse off the remaining salt, a flow rate close to the actual work should be used to flush the resin with raw water. The final effluent from this process should be soft water that meets the standard. In general, the fast flushing process takes 5-15 minutes.

4、 Application field

It is widely used in hot water boiler systems, heat exchange systems, industrial cooling systems, central air conditioning systems, and other water equipment systems.
