Product Description
VEOLIA Reverse Osmosis EDI Membrane Stack Electro-Deionization General Industrial Stacks
For many years, operators of pure water production systems were trying to find a technology to replace mixed bed ion exchange for final demineralization. The operating cost as well as the complexity and risks associated with acid and caustic regeneration were frustrations to these operators. EDI became established as the innovative alternative solution by reducing operating costs, improving site environmental, health, and safety risk profiles, and producing a continuous and steady supply of pure and ultrapure water.
Production of pure water has evolved from conventional pretreatment with multiple stages of ion exchange in initial and final demineralization to the following membrane based operations,including EDI, that are now considered to be best practice by many customers around the world.

EDI utilizes both traditional ion exchange resin and ion exchange membrane to remove contaminants, including those that are uncharged or lightly charged in the feed water such as silica and boron. The biggest advantage lies in the fact that EDI technology employs direct current to drive contaminants out of the feed water and through the ion exchange membranes into the concentrate channels. The direct current also splits water into hydrogen and hydroxyl ions which act as continuous regenerating agents so that contaminants do not accumulate on the ion exchange resin. Therefore, EDI can continuously and predictably produce high-purity and ultrapure water with equal or better quality than mixed bed ion exchange.

E-Cell EDI Stack Features And Benefits
• Low energy consumption
• Leading product water quality, in part 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. E-Cell stacks are manufactured in accordance with the Islamic Food and Nutrition Council of America (IFANCA) standards
