Product Details:
To meet the needs of users, to meet the relevant industry standard water quality (0.1-18 MΩ.CM), small deionized water equipment as much as possible to reduce pollution at all levels to extend the service life of equipment and reduce the maintenance workload of the operator. In the process design, take the municipal tap water as the source of water, through the media filter, activated carbon filter, sodium ion softener, precision filter and other pretreatment system, RO reverse osmosis host system, ion exchange mixed bed (or EDI Desalination system) system, etc., can make the water resistance value of 0.1-18 MΩ.CM. In the case of
The main function of the small deionized water equipment is to remove the ions in the water and reduce the electrical conductivity of the water. According to the water quality can be divided into the following categories:
Class A deionized water requires only a large portion of the water to be removed to purify the water, and the type of deionized water is usually in the range of 200 to 10 μs;
Class B deionized water conductivity is usually 1-10μs, belonging to the food level, can be directly consumed.
Class C deionized water conductivity is usually 0.1-0.9μs, belonging to the fine industrial level, mainly widely used in industrial production process.
D-type deionized water conductivity is usually above 0.06μs, belonging to the electronic level, mainly used in electronic cleaning.
Deionized water produced by small deionized water equipment is often used in the microelectronics industry, the semiconductor industry, power generation industry, the pharmaceutical industry and laboratories. Small deionized water equipment can also be used as pharmaceutical distilled water, food and beverage production water, power plant boiler feed water. Often the process of making deionized water is: reverse osmosis, ion exchange, mixed bed, electrodialysis, distillation, EDI and so on.
Yin and yang mixed bed small deionized water equipment principle:
The use of anion and cation exchange is a special solid adsorption process, which is carried out by the ion exchange agent in the electrolyte solution. It can draw some kind of cation or anion from the electrolyte solution, and put another kind of ion with the same charge sign contained in the same amount and release it into the solution, which is called ion exchange.
EDI small deionized water equipment principle:
EDI deionization equipment is the electrodialysis and ion exchange combined with each other in the new process of desalination. Replacement of traditional mixed ion - exchange desalination process with electric regenerative ion - exchange desalination process. Through the ion exchange resin and selective ion membrane to achieve high desalination effect, combined with the reverse osmosis combined process so that the water quality of up to 10 ~ 15Mn-cm high desalination effect, combined with reverse osmosis combined water production up to 10 ~ 15Mn-cm high standard water production.EDI standard component design can be combined into different specifications according to the requirements of the system. Water production: 0.5m3 / h-400m3 / h
Electrodialysis small deionized water equipment principle:
Under the action of the DC electric field, the ionization of the electric ions in the water passing through the separator occurs, because the exchange membrane is selective for ions. Electrode between a pair of electrodes, by the film, the sun film and the partition (A, B) alternately arranged to form a thick room and light room (that is, cation can be through the sun, the anion can pass through the film The water in the water to the positive direction of the migration of the negative film, the green film in the dark room, so that the number of ions in the water through the light chamber gradually Reduce, become fresh water, and the strong room of the water, due to the strong room of the cation and the influx, the dielectric ion concentration continues to rise, and become concentrated water, so as to achieve the purpose of desalination, purification, concentration or refining.
