Why does the purity of soft water salt affect the quality of soft water?

The main component of soft water salt is sodium chloride. Of course, for a water softener, the main component of soft water salt is sodium ions in sodium chloride.

Due to the increasing demand for process water in modern enterprises, water softeners have gradually become popular. So we are no strangers to the working principle of water softeners. The main substances treated by the resin in the water softener are calcium and magnesium ions in the raw water that are prone to cause scaling. However, the content of calcium and magnesium ions treated per unit area is fixed. Therefore, when the adsorption capacity of the resin reaches saturation, it is necessary to use water softener salt to reduce the adsorption capacity of the resin. However, the resin only treats calcium and magnesium ions in the raw water and has no effect on other substances. Therefore, there are corresponding requirements for the soft water salt used as a regenerant, that is, its purity must be high.

The higher the purity of the soft water salt, the better the output effect of the soft water. If consumers use soft water salts with lower purity, it will affect the water output effect of the water softener. If the impurities contain substances such as iron ions, it will affect the service life of the resin in the water softener. So when purchasing, it is necessary to buy soft water salt with high purity.
