Electrodialysis equipment
First, the general situation of fresh water in general refers to the amount of high salt water after the addition of salt treatment. A home page that can meet the drinking water and food. Because it is part of desalination, so called desalination. Water desalination processing in the most commonly used methods are: electrodialysis, reverse osmosis, ion exchange method, and electrodialysis in seawater and brackish water desalination or primary desalination of salt, which can produce meets the requirements of production and living water, and has the advantages of simple equipment, convenient operation and management, therefore prepared by promoting the use of. Second, the working principle of electrodialysis is by ion exchange membrane on the negative and positive examples in solution choice through, with a DC electric field as the driving force of the film separation method, it is the solute and solvent separation of a physical chemistry process.
Third, process selection and raw water pre treatment that electrodialysis is a unit of the desalting process, and other desalination technology cooperation, achieve the desired purpose. The concentration of electrodialysis desalination process:
1, raw water pretreatment, electrodialysis, desalted water; this is a simple process of desalted water or pure water used in primary production industry.

2. Raw water, pre processing, electrodialysis, sterilized, desalted water; by seawater, brackish water to produce drinking water or from water to produce food and beverage water can take this process. 

3, raw water pretreatment, electrodialysis, ion exchange, desalted water; the process for preparation of pure water and ultrapure water. 

4. Raw water, pre treatment, softening, electrodialysis, desalination of water; the process for to deal with high hardness, high sulfate water, or hardness of bitter salt water (can be concentrated water softening and regeneration agent). 

5 others: can also be combined with reverse osmosis, ultrafiltration, production of medicine, electronic engineering

Industrial water. Raw water after treatment should be consistent with the electrodialyzer influent water quality indicators。
