EDI Continuous Electrodeionization Technology
Product Description:
- Combines electrodialysis and ion exchange in a single module.
- Continuous deep demineralization with automatic resin regeneration.
- Supplies ultrapure water for electronics, semiconductors and pharmaceuticals.
- High-pressure boiler feedwater for the power and thermal power sectors.
Brand: Guangdong Quanwei Environmental Technology Co., Ltd. (Quanwei)
Working Principle
EDI technology skillfully combines electrodialysis and ion exchange within a single module. Driven by an electric field, the system performs continuous deep demineralization while automatically regenerating the ion exchange resin.
Applications
- Electronics and semiconductors: Used in ultra-high-precision cleaning and etching processes for integrated circuits, chips, liquid crystal displays and other components, where even trace impurities can affect product yield.
- Pharmaceuticals and healthcare: Used to produce water for injection, water for sterile preparations and process water for biopharmaceutical production in line with pharmacopoeia standards. These fields impose very strict requirements on microbial and endotoxin control.
- Power and thermal power: Used as feedwater for high-pressure boilers to prevent scaling and corrosion in boilers and steam turbine piping.
- Other high-tech sectors: Including fine chemicals, metallurgy and ultrapure water production for laboratories.
