Electrodeionization (EDI) technology has matured since its commercial introduction over 16 years ago. Acceptance of the technology has been driven by lower costs, higher water quality demands, and improvements in the manufacturing techniques of the product. EDI has not been revolutionary but evolutionary. This paper will review the advancements over the product life cycle and explain the different product offerings available today. EDI, once a proprietary technology, is available to original equipment manufactures (OEMs) and has been accepted not only in the pharmaceutical industry, but semiconductor, power, and all industries that have a need for pure water production.
