Abstract : The effect of temperature on the performance and kinetics of the ultraviolet (UV) disinfection process was investigated using a single lamp annular UV reactor. The reactor was operated to disinfect secondary treated domestic wastewater at 10,.20, 30, 40 and 45°C. The first order rate model and the student t-test were used for data analysis. The effect of temperature in the normal operating range of most treatment plants, i.e., 20 to 40°C, was found not to be statistically significant on the kinetics of the UV disinfection process. The kinetics of the UV disinfection process was highly affected by system operations at extreme temperatures, i.e., at 10and 45°C. In a temperature range of 20 to 40°C, the inactivation rate constant of fecal coliforms was about 590 cm2/mW.sec. A relatively high inactivation rate constant of 770 cm2/mW.sec was noted when the temperature of the disinfected wastewater was increased to 45°C. The inactivated rate constant at 100e was relatively low at 350 cm?/mW.sec. The minimum UV dose required to meet the MEPA fecal coliform standard of 200 organisms/lOO ml, for effluent discharge, was about 180 m'W.sec/cm''.
