一、Process characteristics of deionized water equipment: There are two main processes for deionized water equipment, one is ion exchange equipment and the other is reverse osmosis equipment. Ion exchange equipment is a traditional deionized water equipment. Its product water quality is stable and the cost is relatively low. In the past, the boiler feed water of the power plant used a positive bed + negative bed + mixed bed treatment process. With the development of reverse osmosis, EDI and other processes, the operation of ion exchange equipment is complicated, it is not easy to realize automation, waste of acid and alkali, high operating cost and other shortcomings become more prominent, and more are used in the advanced treatment of reverse osmosis. At present, reverse osmosis deionized water equipment is the most widely used type. Some special industries that require high water quality adopt the combination of reverse osmosis and mixed bed or the combination of reverse osmosis and EDI combined deionized water ultrapure water equipment. It can reach the theoretical ultrapure water standard of 18.25 megohms. 二、Application fields of deionized water equipment: 1. The industrial ultrapure water treatment process is one of the most widely used processes for the preparation of industrial ultrapure water. 2. It can be used in industrial deionization equipment such as sugar making, monosodium glutamate, wine refining, and biological products. 3. Metal ions in electroplating waste liquid, recovery of useful substances in film production waste liquid, etc. 4. Hydrometallurgy and other ion exchange resins can separate, enrich, purify uranium and extract rare earth elements and precious metals from depleted uranium ore. 6. In the synthetic chemistry and petrochemical industries, acids and bases are commonly used as catalysts for esterification, hydrolysis, transesterification, hydration and other reactions in organic synthesis. 7. Battery industry: deionized water equipment for battery production, deionized water equipment for bamboo production of lithium batteries, ultrapure water deionized water equipment for solar battery production; 8. Textile printing and dyeing industry: printing and dyeing auxiliary preparation deionized water equipment, deionized water high-purity water equipment for wet wipes, and deionized water equipment for facial masks; 9. Equipment for preparing deionized water with concrete admixtures; deionized water equipment for glass coating, deionized water equipment for cleaning glass products, and deionized water equipment for cleaning lamps; 10. Electronic industry: aluminum foil cleaning; electron tube spraying and liquid preparation; kinescope; glass bulb cleaning, precipitation, dampness, film washing, tube neck cleaning; LCD screen cleaning and liquid preparation: silicon wafer cleaning water for transistors and integrated circuits , Preparation of water; 11. Cosmetic industry: pure water equipment for skin care products, pure water treatment equipment for shampoo production, deionized water equipment for hair dye production, deionized ultrapure water equipment for toothpaste production, deionized water machine for hand sanitizer production ； 12. Painting industry: paint preparation deionized water equipment, electroplating preparation and cleaning deionized water equipment, electrophoretic paint preparation and cleaning deionized water equipment, etc.
