3、 Equipment brand: Wenzhou Haineng wzhdn

gd55光大彩票4、 Product function description:

1. Sterile water tank:

As a sterile tank unit, a sterile tank is connected with EDI device and ultraviolet sterilization device. The aseptic time of aseptic tank is longer than the production time, which not only ensures the product quality of continuous production, but also avoids reheating of products due to production stop or equipment overload. Another advantage is that the sterilization intermediate storage tank of sterile products ensures that subsequent production can be carried out even in CIP.

2. Terminal filter:

The microorganism and heat source can be completely removed by using microporous filter membrane with absolute pore diameter of 0.22um, which can ensure the sterile water supply and meet the requirements of pharmaceutical water

3. Ultra pure water equipment (EDI device for electric desalting)

EDI electric desalting device is used to produce ultra pure water and secondary desalting equipment after reverse osmosis equipment, which can produce up to 10-18.2m Ω / cm. Therefore, it is widely used in microelectronics industry, semiconductor industry, solar photovoltaic industry, fine chemical industry and power generation industry, pharmaceutical industry and laboratory. It can also be used as pharmaceutical distilled water, food and beverage production water, boiler make-up water of power plant, and other applications of ultra-high purity water.

4. PH regulating device:

gd55光大彩票As the water produced by reverse osmosis is slightly acidic, and the pH value after secondary reverse osmosis is small, in order to meet the process requirements, and at the same time, the influent water of the membrane element is required to be neutral, which is of great benefit to the long-term stable operation of the secondary reverse osmosis membrane, desalination rate and water production. Therefore, it is necessary to adjust the pH of feed water to neutral before the secondary RO membrane. The automatic dosing system adopts German aldoux or American Milton Luo metering pump, which is accurate and reliable. The dosage is about 2-5ppm. 　

5、 Working principle:

gd55光大彩票◇ The electrodeionization (EDI) system is a kind of scientific water treatment technology, which is used to purify the water quality through the selection of ion through the exchange membrane under the action of direct current electric field and directional movement of dielectric ions in water through the diaphragm. A pair of electrodes in an electrodialyzer are usually arranged alternately by a negative membrane, a positive membrane and a separator (A and b) to form a concentration chamber and a light chamber (i.e., cations can pass through the positive membrane and anions can pass through the anion membrane).

gd55光大彩票◇ In the dilute chamber water, the cation migrates to the negative electrode, passes through the positive membrane and is intercepted by the negative membrane in the concentration chamber; the anion in the water moves to the positive direction and is intercepted by the positive membrane in the concentration chamber, so that the number of Li ions in the water passing through the dilute chamber is gradually reduced and becomes fresh water. However, the water in the concentrated chamber becomes concentrated water due to the continuous influx of positive and negative ions in the concentration chamber, and the concentration of dielectric ions increases continuously To achieve the purpose of desalination, purification, concentration or refining.

◇ Chemical water treatment in power plant;

gd55光大彩票◇ Process water for pharmaceutical industry;

◇ Desalination of seawater and brackish water.

7、 Equipment advantages:

1. No acid-base regeneration is required

gd55光大彩票In the mixed bed, the resin needs to be regenerated with chemical acid and alkali, while EDI eliminates the treatment of these harmful substances and heavy work, thus protecting the environment.

2. Continuous and simple operation:

In the mixed bed, due to each regeneration and the change of water quality, the operation process becomes complicated, while the water production process of EDI is stable and continuous, and the water quality is constant. There is no complicated operation procedure, so the operation is greatly simplified.

3. Reduced installation requirements:

EDI system has different volume compared with the mixed bed with equivalent treatment capacity. It adopts building block structure and can be flexibly constructed according to the height and width of the site. Modular design makes EDI easy to maintain in production.
