What's Up with Hexavalent Chromium? A Summary of Potential Regulation Actions and Treatment Technologies
The purpose of this presentation is to inform utilities about regulatory and treatment aspects of Cr(VI) issue. To do this the presentation will provide an overview about what is known about chromium chemistry, occurrence, health effects, and treatment. In particular the presentation will focus on the results of a WaterResearch Foundation Study, performed by the author, which evaluated Cr(VI) treatment technologies. The study concluded that membrane process, anion exchange and reduction/precipitation are feasible treatment methods, as long as treatment objectives remain about approximately 2 ppb.
