Industrial ultrapure water equipment

　　Ultra-pure water equipment is a water treatment device that uses methods such as pretreatment, reverse osmosis technology, ultra-purification treatment, and post-treatment to almost remove conductive media from water, and also remove colloidal substances, gases, and organic matter that do not dissociate to a very low extent.

　　The core desalination component of the ultra-pure water system equipment is the imported reverse osmosis membrane module. The ultra-pure water system equipment is usually composed of a pretreatment section, a reverse osmosis main unit section, and a post-treatment section.

　　1The pretreatment process consists of quartz sand filters, activated carbon filters, fully automatic water softeners and precision filters(Our company adopts fully automatic control valve heads)Ultrafiltration systems can also be selected as pretreatment, but usually the engineering cost is higher. The main purpose of pretreatment is to remove sediment, rust, colloidal substances, suspended solids, color, odor and biochemical organic matter contained in the raw water. When the hardness of the raw water is relatively high, a fully automatic water softener can be selected. This effectively protects the reverse osmosis membrane and thus extends its service life.

　　2The reverse osmosis main unit is mainly composed of a high-pressure pump, membrane housing, imported reverse osmosis membrane modules, online instruments, control electrical equipment, etc. As long as the number of membranes and the model of the pump are properly selected, the desalination rate and water production of the reverse osmosis main unit can both reach the rated indicators, and the conductivity of the effluent can be guaranteed≤10us.

　　3The post-treatment section is to further deepen the treatment of the pure water produced by reverse osmosis to produce ultrapure water, which is usually an ion exchange mixed bed device orEDIAccording to the customer's requirements, the water resistance rate of the equipment can reach18.2MΩ.CMIf it is applied to the direct drinking water process, only a device needs to be added, usually a UV generator or an ozone generator, so that the produced water meets the direct drinking water standard.

　　The exchange reaction takes place in the pure chemical chamber of the module, where anion exchange resins exchange their hydrogen-oxygen ions(OH)It's time to exchange the anion in the dissolved salt(Such as chloride ionsCl). Correspondingly, cation exchange resins use their hydrogen ions(H)To exchange the cations in the dissolved salts(Such asNa).

　　This kind of water contains only water molecules(H20)In addition, there are almost no impurities, no viruses, no organic substances such as chlorinated dioxins, and of course, no trace elements of minerals that the human body needs. Ultra-pure water has no hardness and a relatively sweet taste, and is often called soft water. It can be drunk directly or boiled. Industrial ultrapure water equipment is a level that is difficult to achieve through general processes, such as the resistivity of water being greater than18MΩ*cmClose to18.3MΩ*cmThen it is called ultrapure water.
