Ozone Waste Water Treatment

COD/BOD Removal with Ozone Injection System

The table below shows selected results of tests using the an ozone injection system at 3-4.5% conc. by wt. to treat wastewater for the reduction of COD/BOD. It should be noted that not all BOD/COD is amenable to treatment with ozone. Some specifies are completely unaffected by ozone and others are converted to more biodegradable compounds which can actually
increase BOD. As shown below, in cases where ozone is effective, using an Ozone Generator has shown very high COD
removed/Ozone transferred ratios.

waste water Treatment

Ozone is used effectively in the processing of water laden with concentrations of industrial byproducts. Pesticides, organics, BOD and COD are all treated thoroughly and effectively through ozone oxidation.

Due to the degree of variation in contaminant makeup and loading, waste water treatment equipment is usually specified after scaled down pilot testing has been performed to determine required ozone dosages.

Reduction in processing costs, as well as reduction or elimination of penalties imposed due to disposal of contaminated water are some of the benefits. Further benefits include use of a clean, environmentally friendly technology that is as effective and economical as less friendly technologies.
