A Review of Chlorine Dioxide in Drinking Water Treatment

Abstract

There is increased interest in using chlorine dioxide to treat drinking water for trihalomethane control, taste and odor control, oxidation of iron and manganese, and oxidant‐enhanced coagulation‐sedimentation. This article reviews the physical, chemical, and biological properties of chlorine dioxide as they relate to water treatment. The generation reactions as well as the reactions likely to occur in treated water are presented. In addition, the biological properties of chlorine dioxide are reviewed and compared with other common disinfectants.

Development of chlorine dioxide-related by-product models for drinking water treatment

“…Chlorine dioxide, a compound which is part of the oxochlorine family (Aieta and Berg, 1986). is found to be quise stable in acidic as well as neutral mixtures (Rosenblatt, 1978).…”

“…Since chlorine dioxide reacts prharily as an oxidant, few chlorinated organic compounds, either volatile or nonvolatile, are expected to be produced (Aieta and Berg, 1986; Narkis et al, 1995).…”

Response surface modeling for the inactivation ofBacillus subtilissubsp.nigerspores by chlorine dioxide gas in an enclosed space

“…Chlorine dioxide (ClO 2 ) is a strong oxidizing decontaminant with a broad and high biocidal effectiveness (Aieta and Berg, 1986). It has been approved as a disinfectant for agricultural, commercial, industrial, medical, and residential use (U.S. Environmental Protection Agency [EPA], 2006).…”

Spiral-shaped reactor for water disinfection

“…Water disinfection for public consumption has been used with great efficiency to destroy or inactivate pathogenic micro-organisms. Since the discovery of chlorine and its usage as a disinfectant [1,2], the number of diseases related to water consumption has decreased considerably due to the destruction of microorganisms harmful to health [3]. Although other alternatives emerged such as ozonation and UV disinfection, chlorine remains widely used, as the process has proved its efficiency at low price and simple technology.…”
