Working principle of soft water salt:
There are many water treatment methods, but the most important, advanced and applicable water treatment technology is ion exchange technology. The ion exchange resin of advanced water purifier is usually sodium sulfonate ion exchange resin. After the raw water to be treated passes through the resin, harmful impurity ions (mainly calcium and magnesium ions) in the water can be adsorbed in the resin to achieve the purpose of purifying water quality. With the increase of water treatment capacity, more and more impurities are adsorbed, and the adsorption capacity of resin will gradually decrease. In order to remove the impurities (mainly calcium and magnesium ions) adsorbed by the resin, it is necessary to replace the impurities (mainly calcium and magnesium ions) adsorbed by the resin with sodium ions (Na) through ion exchange to restore the adsorption capacity of the ion exchange resin. This process is also called ion exchange resin.
Characteristics of soft water salt:
1, the higher the purity of salt, the better the use effect.
2. The structure of soft water salt should be compact, the stronger it is, the more durable it is, and it is not easy to agglomerate, with long service life, which also ensures the cleanliness of the soft water machine box.
3. The shapes of soft water and salt are the same, and there is no need to bridge, which can ensure the quality and regeneration effect of soft water.
At present, the most common soft water salt in the market is produced by Zhongyan Company, and the best quality is BWT German Times soft water salt, which is imported from Germany and has a good reputation among high-end consumers. Although its price is slightly higher than that of similar products in the market, it is loved by everyone because of its high purity, compact structure, good regeneration effect and long service life. The average cost of using it for one year is basically the same as that of domestic salt.
Drinking raw water in the Middle Ages almost caused genocide in the West.
Historically, our ancient people's awareness of food safety was ahead of that of the West. One of the reasons why Chinese civilization has lasted for thousands of years without faults is that we drank boiled water very early. In the west, drinking raw water, only the great plague in the Middle Ages is as serious as genocide.
