EDI Electrodeionization Water Equipment Introduction
EDI electrodeionization water equipment is a new type of deep desalination unit. It requires no chemical regeneration and removes trace ionic impurities in raw water through the synergistic effect of electric field and ion exchange resin. Core components include EDI membrane stack, ion exchange resin, electrodes, power supply and control system. The effluent resistivity can reach 15-18.25MΩ·cm, meeting ultrapure water demands in electronics, pharmaceutical and other high-end industries. Featuring high automation and stable operation, the equipment is suitable for feed water such as pretreated municipal tap water and RO permeate water. Xi'an DIEN Water Treatment can customize EDI electrodeionization water equipment with exclusive specifications according to enterprise production capacity, balancing high water purity and energy saving.
Working Principle of EDI Electrodeionization Water Equipment
The core working principle of EDI electrodeionization water equipment is the synergy of **electric field driving + ion exchange + membrane separation**. Under the action of DC electric field, ions in water migrate toward corresponding electrodes, adsorbed and transmitted by ion exchange resin, then separated by ion selective membranes to realize efficient ion removal. Meanwhile, hydrogen and hydroxide ions generated by the electric field achieve real-time self-regeneration of the resin without adding chemical agents such as hydrochloric acid and sodium hydroxide, fundamentally avoiding secondary pollution. Xi'an DIEN Water Treatment optimizes electric field parameters to improve desalination efficiency and operational stability.
Advantages of EDI Electrodeionization Water Equipment
The core advantages of EDI electrodeionization water equipment perfectly match the demands of high-end industries: First, eco-friendly and green. No chemical regeneration is needed with no acid-base wastewater discharge, complying with the low-carbon production trend. Second, high and stable water purity. It continuously produces stable ultrapure water without water quality fluctuation caused by resin regeneration. Third, low operating cost. It saves expenses on chemical procurement, storage and wastewater treatment with convenient daily maintenance. Fourth, high automation. The PLC control system supports fully automatic unmanned operation, perfectly adapting to large-scale continuous production.
Application Fields of EDI Electrodeionization Water Equipment
EDI electrodeionization water equipment is widely applied in high-end industries: In the electronics industry, it is used for semiconductor chip and photovoltaic cell production to guarantee product performance. In the pharmaceutical industry, it produces purified water complying with GMP standards for pharmaceutical preparation and medical device cleaning. In general industry, it serves as boiler make-up water and precision electroplating water to prevent equipment scaling and corrosion. It is also suitable for laboratory scientific research and new energy material production. Xi'an DIEN Water Treatment optimizes equipment configuration according to industry characteristics to fit specific production scenarios.
