The main operating variables affecting ozonation efficiencies of wastewater from beet molasses alcoholic fermentation have been studied. Semibatch experiments have been performed in order to analyze the influence of pH, bicarbonate ion, temperature and stirring rate on color and organic matter removals. The efficiencies were similar regardless of the pH, which indicates that direct reactions of ozone...
Color removal from biologically pre-treated molasses wastewater by means of chemical oxidation with ozone has been investigated. Batch experiments have been performed in order to analyze the influence of ozone dosage and reaction time on color removal, molecular weight distribution and decolorization kinetics. Depending on the applied ozone dosage, color removal from 71% to 93% and COD reduction from...
