There are two commonly used water softening techniques for water softeners. One is to remove calcium and magnesium ions from water through ion exchange resins, reducing the hardness of water quality; Another type is nanocrystalline TAC technology, which utilizes the high energy generated by nanocrystals to package free calcium, magnesium, and bicarbonate ions in water into nanoscale crystals, thereby preventing the formation of scale by free ions. Compared with tap water, soft water has a very clear taste and feel. Soft water has a high oxygen content and low hardness, which can effectively prevent stone disease, reduce the burden on the heart and kidneys, and is beneficial for health.
