(Yet more) challenges for water treatment plants: potential contribution of hypochlorite solutions to bromate, chlorate, chlorite and perchlorate in drinking water

The aim of this study was to evaluate if chlorate, chlorite, perchlorate and bromate ions are found in treated water from 16 Canadian drinking water treatment plants (WTPs) that use hypochlorite as a disinfectant. The WTPs in this survey had unusually high concentrations of sodium, bromide and dissolved organic carbon in the source water and all used ammonium in the treatment train. Samples ...

Chemically modified chitosan polymers for bromate removal

Bromate is a harmful byproduct formed during drinking water disinfection processes. In this work, adsorption of bromate by natural chitosan and its chemically modified polymers has been ...

Water analysis: bromate round robin test confirms superiority of the triiodide method

Bromate is a potential carcinogen and is generated by the oxidation of bromide traces during water disinfection by ozonization. A recently conducted round robin test has confirmed ion chromatography followed by post column reaction and ultraviolet ...
