AbstractTwo published criteria for analyzing and optimizing Advanced Oxidation Processes are compared with respect to their usefulness for process optimization and for determination of the most cost-effective of several candidate processes for a particular application. The Cumulative Efficiency (CE) method compares the amount of target contaminant removed per amount of oxidant used. The Electrical Energy per Mass (EE/M) method compares electrical energy required per kilogram of target pollutant removed. The methods were evaluated using data from treatability studies for DOC removal from a ground water contaminated with 50 mg/L of organic carbon, using processes consisting of combinations of ozone, hydrogen peroxide, and ultraviolet light. It was found that the CE method gave better information about how to manipulate the chemistry for optimization, while the EE/M method provided clearer guidance for process selection on economic grounds, making the methods complimentary in treatability studies. The CE method also predicted that a tandem process might function more efficiently than either of the component single processes, which was found experimentally to be the case.

In this study, the application of ozonation and ozonation with hydrogen peroxide processes for landfill leachate treatment was investigated. The effluents were characterized by COD 710 mgO2/dm3 and BOD5 72 mg O2/dm3. According to the adopted indicators, the determined BOD/COD ratio of 0.1 in raw leachates indicates a stabilized landfill. Ozone was applied at doses of 0.15 - 0.6 gO3/dm3, and hydrogen peroxide at such doses to keep the weight ratios of H2O2/O3 0.4 - 1.6. The maximum COD and UV absorbance removal was respectively 29% and 51% by applying a high ozone dose of 0.6 gO3/dm3. After oxidation, the ratio of BOD/COD was increased from 0.1 up to 0.3. It has been shown that by using hydrogen peroxide in ozonation, organic compounds expressed as COD can be efficiently removed from the effluents. The best conditions for the H2O2/O3 process were obtained with a H2O2/O3 ratio of 0.8 and ozone dose of 0.6 gO3/dm3. Under these conditions, the removal efficiency of COD was 46%.
