Strategies for minimizing ozonation by-products in drinking water
Article Abstract:
The use of ozone as a disinfecting agent for drinking water in the US, while emerging as an attractive alternative to chlorination, presents its own problems that must be effectively addressed. These include the potential formation of harmful by-products such as peroxides, aldehydes and bromate ions. Some of the strategies aimed at controlling ozonation by-products include the use of granular activated carbon filters, ultraviolet irradiation and membrane filtration.

Granular activated carbon filtration and chloramine
Article Abstract:
Chloramination in waste water filtered through granular activated carbon (GAC) proceed without interfering with chloramine development. The process, however, results in the production of an unknown reactant that causes the disinfectant's slow dissipation rate. Chloramine produced via GAC-filtered effluent water exhibited unstable characteristics when compared with chloramine formed using the traditional basin and sand filtration techniques.
