EDI is a process which combines semi-impermeable membrane technology and is commonly used as a post treatment of reverse osmosis (RO).

This application is typically used at power stations, pharmaceutical industry and other process industries.

In comparison to conventional DI, EDI provides many benefits:

• Continuous water supply
• Smaller footprint
• No need off-site regeneration
• No need for chemical handling
• No hazardous waste stream
• Consistent water quality
• Reduced operational cost (chemicals, water)
