EDI ultrapure water equipment
EDI, also known as continuous electrodialysis technology, scientifically integrates electrodialysis technology and ion exchange technology. Through the selective permeation of cations and anions by cation and anion membranes and the exchange of ions in water by ion exchange resins, the directional migration of ions in water is achieved under the action of an electric field, thereby achieving deep purification and desalination of water. The hydrogen ions and hydroxide ions generated by water electrolysis are used to continuously regenerate the loaded resin. Therefore, the EDI water production process does not require acid or alkali chemical regeneration to continuously produce high-quality ultrapure water. (1). Optimum water quality stability.
(2). Continuously produces ultrapure water that meets user requirements.
(3). Modular production with fully automated control.
(4). No acid or alkali regeneration required, no wastewater discharge
(5). No downtime due to regeneration.
(6). No regeneration equipment or chemical storage and transportation required
(7). Compact equipment structure, small footprint.
(8). Low operating and maintenance costs.
(9). Simple operation and low labor intensity. Ultrapure water is commonly used in the microelectronics, semiconductor, power generation, pharmaceutical, and laboratory industries. EDI-purified water can also be used as pharmaceutical distilled water, food and beverage production water, chemical plant process water, and other ultrapure water applications.
