Abstract |
In this research, the levels of concentrations from the junction of effluent from wastewater treatment plant during dry days and combined with runoff from the surrounding 11 ha livestock catchment area during wet days were determined to investigate the relationships of the concentration of various pollutants such as particulates, nutrients and organics originating from point and nonpoint sources. Manual sampling was conducted from October 2008 to December 2011 during dry and wet days. Based on the results, the flow rates and concentrations of most pollutant parameters were increased during wet days. It was found out that the effluent wastewater combined with stormwater runoff has low BOD to TN/TP ratio and high TN/TP to BOD ratio. Therefore, it is needed to employ other treatment methods to effectively manage the wastewater and reduce the pollutant discharge to receiving water bodies. |
