Ion‐exchange (IX) resin is perhaps the most promising technology to remove the contaminantperchlorate (ClO 4 − ) from waters. However, ion exchange is only a separationtechnology that transfers the perchlorate from waters to the waste solutions used to regenerate the resins. Thewaste solutions contain high perchlorate concentrations, and treatment technologies for these regenerantsolutions are needed. In this article, we review the latest knowledge on perchlorate removal byion‐exchange resins; propose three systems that combine ion‐exchange resins (forperchlorate removal) and biological reduction for treating the waste solutions resulting from resinregeneration; and discuss the challenges and research needed to fully develop the proposed technology.© 2002 Wiley Periodicals, Inc.
