DI Ultrapure Water Device-Electronic Optical Disc Production Water

Ultrapure water equipment:

Ultrapure water equipment is a pretreatment + reverse osmosis + edi system, which can effectively remove all kinds of salts, impurities, bacteria and other water substances in the water, so that the quality of produced water meets the needs of enterprise production water. The system adopts integrated design, modular installation, low energy consumption, small footprint. Ultrapure water equipment system RO reverse osmosis and EDI technology into the constant south steady flow pressure control technology, and the pre-treatment supporting the use of the system has a stable quality of produced water, easy to operate, low operating costs, green pollution-free, easy maintenance and other advantages. Produced water resistivity ≥ 18.2MΩ.CM, temperature 25 ℃

EDI high purity water equipment as the preparation of ultra-pure water equipment, as reverse osmosis equipment after the second desalination equipment, can be made out of up to 10-18.2MΩ.CM. Therefore, it is widely used in microelectronics industry, semiconductor industry, power generation industry, pharmaceutical industry and laboratories. It can also be used as pharmaceutical distilled water, water for food and beverage production, make-up water for boilers in power plants, and high purity water for other applications.

EDI is the use of anion and cation membranes, using a symmetrical stacked form, in the middle of the anion and cation membranes sandwiched between the anion and cation resins, respectively, under the action of direct current voltage, anion and cation exchange. And at the same time under the action of the voltage gradient, water electrolysis will occur to produce a large number of H + and OH -, these H + and OH - of the ionic membrane in the middle of the anion, cation constantly regenerated. Due to EDI non-stop exchange - regeneration, so that the degree of pure water is getting higher and higher, so, easily produce high purity of high purity water .

edi high purity water equipment is the combination of reverse osmosis technology and ion exchange technology formed after the professional preparation of ultrapure water tools, it uses microcomputer intelligent programme control system, can automatically detect and display the water quality; in obtaining high quality water production at the same time, to ensure that the amount of water.

Ultrapure water is initially the United States scientific and technological community in order to develop ultra-pure materials (semiconductor materials, nano-fine ceramic materials, etc.) the application of distillation, deionisation, reverse osmosis technology or other appropriate supercritical fine technology to produce water, nowadays ultrapure water has been widely used in industry, biology, medicine, automotive, and other fields. This water in addition to water molecules (H20), there is almost no impurities, not to mention bacteria, viruses, chlorinated dioxins and other organic matter, of course, there is no human body needs mineral trace elements, (the resistivity of the water is greater than 15MΩ * cm, close to 18.3MΩ * cm is known as ultrapure water. EDI ultrapure water equipment by the pharmaceutical industry, microelectronics, power generation industry and laboratories are generally accepted! . (The application in surface cleaning, surface coating, electrolysis industry, chemical industry and solar photovoltaic industry is also becoming more and more extensive.)

EDI can replace the traditional mixed ion exchange technology (MB-DI) to produce stable deionised water.

EDI technology has the following advantages over the mixed ion exchange technology:

1. The amount of ion exchange resin is small, equivalent to about 5% of the amount of resin used in the traditional ion exchange method.

2. Ion exchange resin does not need acid, alkali chemical regeneration, saving a lot of acid, alkali and cleaning water, greatly reducing labour intensity.

3. There is no waste acid and alkali discharge, which is a clean production technology and an environmentally friendly product.

4. The process is easy to achieve automatic control, stable quality of produced water, combined with RO and other water treatment technologies, can form a perfect pure water, ultra-pure water production line.

5. High quality of produced water, can reach the national electronic grade water I standard, resistivity of 15-18MΩ-cm, bacterial endotoxin content is less than 0.1mg/L.

6. It has excellent ability to remove weakly dissociated substances (such as carbon dioxide, silicon, boron, ammonia, etc.), which is more suitable for the needs of ultrapure water.

7. Pure water production process is continuous, without the need for a set of ion exchange beds such as a set of in use a set of regeneration repeated settings.
