The 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, and its water quality is stable and the cost is relatively low. In the past, the boiler make-up water in the power plant was treated by cation bed + anion bed + mixed bed. 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, and the disadvantages of high operating cost are more prominent. At present, reverse osmosis deionized water equipment is the most widely used one. For some special industries with high water quality requirements, the combination of reverse osmosis and mixed bed or the combination of reverse osmosis and EDI ultrapure water equipment is used. The maximum can reach the theoretical ultrapure water standard of 18.25 megohms.
The application field of deionized water equipment
1. The industrial ultrapure water treatment process is one of the most widely used processes in the preparation of industrial ultrapure water.
2. It can be used in industrial deionization devices such as sugar, monosodium glutamate, alcohol 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.
5. The synthetic chemistry and petrochemical industries often use acids and bases as catalysts in organic synthesis for esterification, hydrolysis, transesterification, hydration and other reactions.
