Sustainable Performance of Wastewater Treatment Plant : A case study of Wupa sewage treatment plant

This research was conducted to ascertain the sustainable performance of Wupa sewage treatment plant at Abuja Municipal Area Council, FCT. The aim of the study was to investigate the level of effectiveness of the treatment plant in removing physiochemical and bacteriological manifestations from the influent before the treated water is discharged to the Wupa River. This involved the experimental analysis of the wastewater samples collected at the influent inlet and the effluent after UV treatment by standard methods and the collation of the acquired results with NESREA and WHO standard effluent limits. The experimental analysis discovered parameters; pH, Temperature, Conductivity, Turbidity, Total Dissolved Solids, Biochemical Oxygen Demand, Total Suspended Solids, Chemical Oxygen Demand, Ammonia, Sulphate, Orthophosphate, Chloride, Dissolved oxygen, Total coliform count and Faecal coliform were observed to be 6.99, 20.6°C, 248 µf/cm, 13 NTU, 160 mg/L, 10 mg/L, 12 mg/L, 25 mg/L, 8 mg/L, 43 mg/L, 1.4 mg/L, 17 mg/L, 6.9 mg/L, 350 CFU/1mL, and 170 MPN/100mL respectively and removal efficiency of 19%, 95.5%, 92.86%, 91.66%, 93.33%, 4.44%, 36.36%, 19.05%, 95.63% and 89.38% respectively. The evaluation revealed an increase in effluent parameters of the pH, Ammonia and Total dissolved solids, although all increased values were within the specified standard discharge limits. However, even though the removal efficiency of the Turbidity was at an excellent rate of 95.5%, the effluent value 13 NTU was still above the standard effluent limit of 5 NTU. On account of the result, adequate maintenance and daily inspection of the clarifiers was encouraged, and an empirical model was created in order to improve sustainable performance of the treatment process.
