EDI Principle Overview - EDI ultra-pure water equipment continuous electrodeionization (Electro deionization), is the use of mixed ion exchange resin adsorption of ions to the water, while the adsorbed ions and the role of DC voltage, respectively, through the yin and yang ion-exchange membrane process is removed. The process of ion exchange resins are continuously regenerated electrical equipment reverse osmosis EDI, there is no need for the use of acid regeneration. This new technology can replace traditional ion exchange unit to produce higher resistivity ultrapure water, usually with the use of EDI and pre-treatment of water and electricity resistance can do 5-15 MΩ.CM principle of reverse osmosis equipment EDI, thereby to meet customer requirements for high water quality. EDI five characteristics: 1, no need to use acid regeneration, without reserve and acid diluted acid transport facilities, safety and reliability, to avoid worker contact with acid; - EDI ultra-pure water equipment 2, saving water and recycling waste water regeneration treatment facilities; 3, reduced operating and maintenance costs; 4, small footprint, simple installation, high water production (95%); 5, continuous operation, product water quality and stability, not because of regeneration downtime. - EDI ultra-pure water equipment EDI process (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. Pretreatment by reverse osmosis, 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, silicon dioxide) These impurities must be removed industrial water desalination. However, the reverse osmosis process for removal of these impurities is less effective. Ion exchange membranes and ion exchange resins EDI equipment works similar to the reverse osmosis water quality standards, 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 are arranged alternately reverse osmosis EDI device configuration, and use web EDI unit apart form each concentrated water chamber. At a given DC voltage driven in fresh water chamber, ion-exchange resin anion and cation respectively positive and negative migration in the electric field, and exchange resin into the concentrate chamber through the anion and cation, while the feed water ions occupy the ion vacancy migration flow ion exchange resin adsorption. 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 reverse osmosis equipment principle | Guangzhou Tianshui (certified) | Guangzhou EDI equipment provided by the Guangzhou Environmental Protection Technology Co., Ltd.
