Abstract Various studies have presented models to predict the performance of constructed wetlands at different temperatures focused on the removal of conventional pollutants, and common configuration of constructed wetlands. Investigations on the effect of temperature on the performance of constructed wetlands treating chlorinated volatile organic compounds are limited to microcosm studies. This study is meant to come up with kinetic and energy balance input data for mathematical models that can be used to predict the performance of upflow constructed treatment wetlands treating chlorinated ethenes and ethanes at different ambient temperatures. Bench scale continuous upflow columns will be conducted to investigate the effect of temperature on the performance of upflow constructed wetlands treating volatile organic compounds (CVOCs). The columns will be packed with two types of wetland bed materials. For the first treatment the constructed wetland will be packed with row crop compost/ soil builder compost/ sand. The second one will be packed with Bion Soil®/Latimer peat/Sand. Both upflow constructed columns will be operated under a controlled environment to simulate field conditions at four phases of temperature (30ºC, 20ºC, 10ºC, and 5ºC). Thermal conductivity coefficients will be determined for wetland bed materials of interest. The results on theses studies will be used as energy balance input data for mathematical models that can be used to predict the performance of upflow constructed treatment wetlands treating chlorinated ethenes and ethanes at different ambient temperatures.
