EDI Module
♦ Main Application:
Electrodeionization (EDI) module engineered for continuous high-purity water production without chemical regeneration, ensuring stable performance, low operating cost, and environmentally friendly operation.
Electrodeionization (EDI) Module
An Electrodeionization (EDI) Module is the core component of an EDI water purification system, designed to continuously remove dissolved ions from RO permeate and produce high-purity water without chemical regeneration.
CHONGYANG WATER supplies high-performance EDI modules for pharmaceutical purified water systems, electronics ultrapure water systems, laboratory water purification systems, biotechnology facilities, power plants, healthcare institutions, and industrial deionized water applications.
What Is an EDI Module?
An EDI Module combines ion exchange resins, ion exchange membranes, and direct current electricity to continuously remove dissolved ions from water.
- Ion exchange resins
- Ion exchange membranes
- Direct current power supply
- Continuous resin regeneration inside the module
- Chemical-free high-purity water production
- Stable low-conductivity and high-resistivity water quality
