How long does it take for ozone to kill bacteria?
A. While ozone kills bacteria on contact, the speed at which ozone neutralizes bacteria is dependent upon the type of bacteria, virus, cyst or other microbiological contaminant present, dissolved ozone concentrations and the organic load in the water. All Water Energy systems are engineered to provide dissolved ozone concentrations in a range of 1.5 to 3.0ppm to the wash wheel. This high level of dissolved ozone is clearly in excess of the minimums required to inactivate all microbiological activity. The required contact times with high levels of dissolved ozone are reduced to fractions of a second for most organisms as specified by EPA regulations for the certification of drinking water.
