Electrodeioniser (EDI)

EDI products are used worldwide in ultra pure water systems in a diverse range of applications in industries, including pharmaceutical, semiconductor, power generation and laboratory pure water systems. 
Electrodeionisation (EDI) is a process in which an electric field is used to remove ions and polar species from an aqueous stream. EDI is used with reverse osmosis to replace ion exchange resin-mixed beds, which require onsite or offsite chemical regeneration.By eliminating resin regenerating chemicals, EDI delivers significant economic and environmental benefits. EDI’s continuous process improves water quality by reducing water quality spikes and upsets.

Advantages of EDI: 

• Enables a simpler system (no concentrate-recirculation)
• Produces ultra pure water (up to 18 megohms/cm)
• Eliminates regeneration chemicals & High recovery of up to 99%
• Capacity ranging from 1/4 gpm to 35 gpm (50 l/hr to 8 m3/hr)
• Continuous production of consistent water quality
• No regeneration is required
• Less foot print & Cost effective

Standard Features

• Package Design with flow rate between 1,000 and 25,000 litres/hr
