Automatic water softener regeneration process is running and operating an automatic control of ion exchange water softener, the use of sodium cation exchange resin to remove calcium and magnesium ions in water, reduce raw water hardness, in order to achieve the purpose of softening hard water, thus avoiding the carbonates pipes, vessels, boiler fouling. Significant savings in investment costs while ensuring smooth production. Application: low-pressure boiler feed water, heat water, cooling circulating water, central air conditioning circulating water, industrial water softening, pretreatment brine, food and beverage, pharmaceutical industry, water, the electronics industry with high water, reverse osmosis systems removed. Can also be used softened water treatment restaurants, hotels, apartments, office buildings and other domestic water treatment and beverage, food, wine, hospitals, printing and dyeing, chemical and other industries.
