Bromate minimization during ozonation: mechanistic considerations

Article Abstract:

Bromate formation during drinking water ozonation is evaluated, and methods for minimizing bromate formation while retaining drinking water quality are discussed, including pH depression, and ammonia addition. Ammonia addition is described as the most effective method for bromate minimization in drinking water.

Role of disinfectant concentration and pH in the inactivation kinetics of Cryptosporidium parvum oocysts with ozone and monochloramine

Article Abstract:

Cryptosporidium parvum oocysts are exposed to ozone and monochloramine disinfection treatments at varying concentrations and pH levels. The inactivation kinetics of the oocysts are graphed for each combination of pH level and disinfectant concentration.
