Bromate is a disinfectant byproduct that is formed after bromine reacts with chemical oxidants such as ozone. This process can occur during the treatment of drinking water. While New Millennium Concepts, Ltd. has not conducted specific testing for bromate, our expectation is that reduction of bromate should occur for the following reasons:

  • Bromate (BrO3-) is composed of bromine and oxygen.
  • Bromate reduction has been reported in several studies to be achieved by the mechanism of adsorption to attract bromate to the surface of the of carbon-based media. Bromate is then reduced down to bromide (Br-).
  • Black Berkey® Purification Elements utilize activated carbon in our proprietary formulation.
  • The Environmental Protection Agency (EPA) has listed dichloroacetic acid as a surrogate chemical for bromate. Surrogates are compounds similar in chemical composition to the analytes of interest and spiked into environmental samples prior to preparation and analysis. They are used to evaluate the efficiency of removal or reduction of other contaminants that react similarly.
  • Black Berkey® Purification Elements reduce dichloroacetic acid by greater than 98.00%.

Nevertheless, since NMCL has no specific testing for bromate, we cannot make any specific claims for bromate reduction. Factors that could have an impact on any reduction would include the concentration of the bromate contamination, as well as other competing contaminants in the water.

New Millennium Concepts, Ltd. always recommends that you use the cleanest source of water available, whenever possible.
