EDI processes (a) - EDI ultra-pure water equipment is generally urban presence of sodium, calcium, magnesium, chloride, nitrate, bicarbonate, and other solutes in the water. The compound represented by the negatively charged anions and positively charged cationic composition. By RO pretreatment, Zhaoqing medicine ultra-pure water equipment, more than 99% of the ions can be removed. In addition, the raw water may also comprise other trace elements, dissolved gases (such as CO2) and some of the weak electrolyte (e.g., boron, Zhaoqing medicine supply ultra-pure water equipment, silica) These impurities must be removed industrial water desalination. However, the reverse osmosis process for removal of these impurities is less effective. Works of ion exchange membranes and ion exchange resins are similar, Zhaoqing medicine ultra-pure water equipment manufacturers, can make specific ion transport. Anion exchange membrane allows only anions, cations not allowed; and the cation exchange membrane opposite. Between a pair of anion and cation exchange membrane filled with mixed ion exchange resin to form an EDI unit. The space between the anion and cation exchange membrane from a mixed ion-exchange resin is known as freshwater occupied room. EDI will be a certain number of units listed together so that the anion exchange membrane and a cation exchange membrane alternately arranged, and the use of mesh separated form each EDI unit concentrated water chamber. At a given DC voltage driven in fresh water chamber, the ion exchange resin to the positive and negative migration of ions in the electric field, respectively, Zhaoqing ultra-pure water equipment wholesale medicine, and through cation-anion exchange resin into the concentrate water room, at the same time, the feed water is ionized ions occupy the ion vacancy migration flow exchange resin. Indeed migration and adsorption of ions occurs simultaneously and continuously. Through this process, the feed water ions pass through the ion exchange membrane into the concentrated water chamber is removed and become demineralized water. - EDI EDI ultra-pure water equipment, ultra-pure water equipment is applied after the reverse osmosis system to replace the traditional mixed-bed ion exchange technology (MB-DI) production of ultra-pure water stable. EDI technology and mixed ion exchange technology has the following advantages: 1, with higher product water quality, up 18.25MΩ * cm ultrapure water standards; 2, desalination rate, the water is more stable; 3, water use rate out up to 95%; 4, the resin without acid regeneration, no sewage, more environmentally friendly; 5, operation, operation, easy maintenance, full automation; 6, the standard design, depending on the product water requirements can continue to accumulate module, to accommodate the larger water production requirements; 7, the flow range from 1m3 / h to 450m3 / h or more; 8, low operating costs, energy consumption, water production per 3.8m3 / h, power 1KW. - EDI ultra-pure water equipment, ultra-pure water equipment Zhaoqing Zhaoqing ultra-pure water equipment, wholesale _ _ Guangzhou Tianshui (certified merchants) are provided by the Guangzhou Environmental Protection Technology Co., Ltd.
