How it works
There are many ways to treat water, but the most important, advanced and suitable water treatment technology is ion exchange technology. The ion exchange resin used in advanced water purification devices is usually a sulfonate-type sodium ion exchange resin. After the raw water to be treated passes through the resin, the harmful impurity ions (mainly calcium Ca, magnesium Mg ions) in the water can be adsorbed into the resin to achieve the purpose of purifying water quality. With the increase of water treatment, more and more adsorbed impurities, the adsorption capacity of the resin will gradually decrease, and to remove the impurities adsorbed by the resin (mainly calcium Ca, magnesium Mg ions), it is necessary to use sodium ions (Na), through the backwashing method, through the ion exchange and the impurity ions adsorbed by the resin (mainly calcium Ca, magnesium Mg ions), displaced, so as to restore the adsorption capacity of the ion exchange resin, this process is also called ion exchange resin regeneration.
