Performance Evaluation of WUPA wastewater Treatment plant Idu - Industrial Area, Abuja

Abstract

The paper evaluates the performance efficiency of WUPA waste water treatment plant. Wastewater samples were collected and monitored in the raw influents, primary effluents and final treatment effluents at three different locations of WUPA waste water treatment plant using standard methods for physiochemical characteristics analysis. The results revealed that the average concentrations of DO, BOD, COD, TSS, TDS, NH4, NO3, and PO4 in the final effluent of WUPA WWTP were 6.7, 22, 50, 13.1, 20, 3.8, 2.73, and 2.4 mg/L respectively and that of electrical conductivity, temprature and pH are 271us (cm), 25.1%, and 7.42 respectively which fell within the standard recommended by WHO for effluent discharge into water bodies. Values of TDS and NO3 however increased from the raw influent to the final treatment effluent instead of decreasing which shows the inefficiencies of the system to effectively reduce the concentration of these parameters. The average removal efficiencies of BOD, COD, TSS and NH4 were found to be 8.28% , 85.88%, 91.44% and 38.71% respectively. The effect of the final treatment effluent on the water quality of WUPA river was also determined by analysing the physiochemical characteristics of the surface water sample collected at two sampling locations 30m away upstream from the discharge point before the effluent meets the river water (S4) and 30m away downstream from the exit point after the effluent meets the river water (S5). Though there were slight increases in the concentrations of the most parameters downstream after the effluent meets the WUPA river, the study has revealed that there was no adverse effect on the physiochemical characteristics of the recieving water
