E-Cell EDI MK-3 / MK-5 / MK-9 (VEOLIA E-CELL EDI, EN brochure)

Summary

Product Identification

The E-Cell Electrodeionization (EDI) stack is an innovative alternative to traditional mixed-bed ion exchange for final demineralization in pure water production systems. It utilizes both traditional ion exchange resin and ion exchange membrane technology, employing direct current to remove contaminants and continuously regenerate the resin. This process splits water into hydrogen and hydroxyl ions, which act as continuous regenerating agents.

Advantages of EDI Compared to Mixed Bed:

• More advanced technology
• No regeneration chemicals or neutralization systems needed
• Much lower operating cost
• Continuous and simplified operation
• A smaller footprint and reduced building height requirement

Typical EDI Applications:

• Semiconductor, microelectronics, solar panel production rinse water and green hydrogen
• Boiler feed water for power generation or the chemical, steel, and metallurgical industries
• Various pharmaceutical industry waters
• Laboratory water

E-Cell EDI Stack Features and Benefits:

• Low energy consumption
• Leading product water quality, due to ion exchange resin filled concentrate and dilute channels as well as a patented ion exchange resin arrangement
• Counter-current operation reduces the possibility of scale formation
• Strong reputation for reliable operation
• Simplified system design does not require degassing the concentrate, a concentrate recirculation loop, or added salts

Quality Assurance:

• CE, RoHS, and CSA marked
• FDA compliant (pharmaceutical modules)
• Manufactured in an ISO 9001 and ISO 14001 certified facility
• Halal certified, manufactured in accordance with IFANCA standards
