Abstract

The direct ozonation is more and more used for waste water treatment. In this study the effect of temperature on the direct ozonation of a wastewater is studied. At constant pH and dissolved organic carbon concentration, the time-dependence of ozone concentration is measured in the function of different temperatures. Continuous experiments are carried out at two temperatures (8 and 17°C), batch experiments are carried out at three temperatures (8, 18 and 27°C). It is shown that with increasing temperature the ozone depletion is faster in both cases. In case of batch experiments the temperature dependence of the reaction kinetic constant is measured. It is found that if the temperature is increased by 10°C doubles the value of the reaction kinetic constant.
