Chromium Oxidation By Disinfectants And Oxidants Used In Drinking Water Treatment, Nathan D. Rogers
Chromium Oxidation By Disinfectants And Oxidants Used In Drinking Water Treatment, Nathan D. Rogers
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This project investigated the behavior of hexavalent chromium (Cr(VI), a potential carcinogen) in drinking water. While Cr(VI) can exist naturally, it can also be oxidized from Cr(III), a known trace nutrient. Recently, the State of California implemented a water regulation specifically for Cr(VI) at 10 parts per billion (ppb). This project completed a comprehensive evaluation of chromium behavior when in contact with common drinking water treatment chemicals including chlorine, monochloramine, chlorine dioxide, potassium permanganate, and ozone.
The results of these oxidation experiments are highly applicable to water treatment facilities. If a treatment plant is using monochloramine, there is no indication …
