Advantages of EDI deionized water equipment and importance of daily maintenance

EDI deionized water equipment, as a new technology for treatment, is a new deionization technology perfectly combined with ion exchange and electrodialysis When water passes through EDI equipment module, it exchanges anion and cation with resin layer in membrane reactor, and produces high-purity water of more than 15 megaohm After the replacement reaction, the anion and cation resins are regenerated by hydrogen and hydrogen oxide ions electrolyzed by water molecules, and then recovered The ability to exchange ions This process of automatic replacement and regeneration has realized the purpose of EDI automatic desalting Its advantages are: 1 No need of acid and alkali regeneration, no environmental pollution; 2 Greatly reducing the floor area of the equipment; 3 Intelligent control, improving work efficiency; 4 High performance, stable and reliable effluent 5 Modular combination, convenient and fast Precautions for routine maintenance of EDI deionized water equipment: The scientific and reasonable design of deionized water equipment is a basic and important part Not only that, correct daily maintenance and operation is also very important Daily maintenance directly affects the service life of the equipment and the water quality and quantity of the produced water, such as improper management, resulting in frequent replacement of consumables and high operation cost 1 Do a good job of operation record and carefully observe and record the technical parameters of each node; 2 Although the general equipment adopts full-automatic intelligent control, it also needs to do a good job of regular inspection; 3 Pay attention to the pretreatment operation equipment, and regularly check whether the automatic cleaning is normal operation? Regularly check whether the effluent water quality is qualified (mainly pollution index and ORP index); 4 Regularly replace the precision filter element, when the inner layer of the filter element is gray, it needs to be replaced in time; 5 Monitor the pressure, flow and water quality indexes of the main reverse osmosis machine at all times, analyze and solve the abnormal problems in time, and clean it in time when chemical cleaning is needed 6 EDI precision electric desalting device, pay attention to the technical parameters of water quality, fresh and concentrated water inlet and outlet pressure, operating voltage and current, and carry out regeneration and chemical cleaning in time according to the change of technical parameters; 7 Polish the resin filter, pay attention to the water quality in daily management, do not enter if it does not meet the design requirements, or it will fail too fast 8 Adhere to the principle that "if the effluent quality of each treatment unit is unqualified, it cannot enter the next treatment unit" Otherwise, increase the treatment load of the next unit, causing irreversible damage The design and material selection are important for the deionized water equipment to operate stably, but the later maintenance is also important, so the user should pay attention to it.
