Secondary Purified Water Machinery for Industry

Product Description

The ultra-pure water system in the electronics industry uses the current advanced electronic technology to refine the pure water system. According to the water quality of the raw water, the raw water is desalinated. Because the electronics industry has very high requirements for the ion content in the water, our company's ultra-pure water system The water system also chooses advanced reverse osmosis technology, combined with the industry's top EDI equipment and mixed bed technology, so that the final produced water quality can reach 18.25Mω?cm, and the water quality can meet domestic and foreign water standards.

Pure water system.
1. The first-stage pretreatment system: the quartz sand multi-media filter is used. The main purpose is to remove the sediment, rust, colloidal matter, suspended matter and other particles in the source water that are harmful to the human body above 20m. The system can automatically ( Manual) Carry out a series of operations such as backwashing and forward washing.
2. The second-stage pretreatment system: the nutshell activated carbon filter is used to remove the pigment, peculiar smell, biochemical organic matter in the water, reduce the residual chlorine value of the water, pesticide pollution and other pollutants harmful to the human body. The system can automatically (manually) perform a series of operations such as backwashing and forward washing.
3. The third-level pretreatment system: the use of cation resin to soften the water, mainly to reduce the hardness of the water, remove the calcium and magnesium ions (the main components of the formation of scale) in the water, which can effectively extend the service life of the reverse osmosis membrane, and Intelligent resin regeneration can be carried out.
4. The fourth-stage pretreatment system: adopts a 5um pore size precision filter to further purify the water and optimize the turbidity and chromaticity of the water. Ensure the requirements of RO system water inlet conditions, ensure the quality of water produced by the equipment, and extend the service life of the equipment.
5. Ultraviolet disinfection: With the help of short-wave (180nm-254 nm) ultraviolet radiation, the small organic compounds in the water that are not easily adsorbed by activated carbon, such as methanol, ethanol, etc., are converted into CO2 and water to reduce the TOC index.
6. Ion exchange: It is known that a mixed ion exchange bed is a decisive means to remove ions from water. It is not difficult to obtain ultrapure water by means of a multi-stage mixed bed. But the TOC index of water mainly comes from the resin bed. Therefore, high-quality ion exchange resin becomes the key to success. The so-called high-quality resin is a resin that has particularly good chemical stability, does not decompose, and does not contain oligomers, monomers, and additives.
7. EDI equipment: through the selective permeation of cation and anion membranes of cation and anion membranes and the exchange of ions in water by ion exchange resins, the directional migration of ions in water is realized under the action of electric field, so as to achieve deep water purification and desalination. , And the filling resin is continuously regenerated by the hydrogen ions and hydroxide ions produced by water electrolysis. Therefore, the EDI water production process does not require acid and alkali chemical regeneration to continuously produce high-quality ultra-pure water.
