Accurate In-Line Dissolved Ozone Measurements In Bottled Water

The measurement of dissolved ozone in the bottled water industry has two main concerns that need consideration when using process instrumentation to monitor O₃ concentrations. First, the use of O₃ as a disinfectant must not create any additional bi-products that affect the water quality, such as the formation of bromate from water containing bromide. In addition, ozone production uses electricity, and in many facilities oxygen, so it is critical to minimize the ozone concentration and deliver the optimal level of ozone in the process.
