제목 Prediction of Oxidant Exposures and Micropollutant Abatement during Ozonation Using a Machine Learning Method
초록 The oxidation of micropollutants (MPs) by ozonation proceeds via the reactions with molecular ozone (O3) and hydroxyl radical (•OH). To predict MP abatement during ozonation, developing a model that can accurately predict oxidant exposures needs to be preceded. This study demonstrates machine learning models based on the Random Forest (RF) algorithm to output oxidant exposures from water quality parameters including fluorescence excitation-emission matrix (FEEM) data for organic matter characterization. Oxidant exposure of sixty natural waters and wastewater effluents samples were determined. Models using high resolution FEEM data generally exhibited high prediction accuracy, implying that the organic matter characteristics quantified by FEEM can be important factors to improve the accuracy of the prediction model.
