Abstract

The study examined efficiency and seasonal variations in municipal wastewater treatment in Federal Capital Territory, Abuja. Wastewater treatment data from year 2015 to 2018 were analysed and compared with National Environmental Standard and Regulations Enforcement Agency permissible limit. The data were analysed to determine if seasonal variations exist in the performance of the wastewater treatment plant. The study was undertaken in the wastewater treatment plant located at Wupa, Abuja. The result obtained show that in 2015 a high reduction in biochemical oxygen demand (BOD) (84.6%) and chemical oxygen demand (COD) (85.4%) with excellent pH value (7.3pH, 90.8%) was achieved. In 2016, there was a significantly high level of treatment in Faecal Coliform (99.1%), BOD (93.4%), total suspended solids (TSS) (91.7%), COD (87.6%), and Ammonia (71.5%). In 2017, the level of treatment for BOD, COD and TSS were 97.2%, 95.7% and 95.4% respectively. While in 2018, removal efficiency of BOD was 95.2%, COD 91.6% and TSS 90.6%. The result also revealed that the observed values of the biochemical parameters are considerably lower when compared with the National Environmental Standards, Regulations and Enforcement Agency (NESREA) standards (i.e., p<0.05). The seasonal comparative result shows that the BOD total in dry season is significantly higher compared to the rainy season (t*=-3.553, p=0.001<0.05). The average COD in rainy season is slightly lower compared to that in dry season, and however, statistically insignificant (t*=-1.690, p=0.098). The TSS and pH values in rainy season are slightly and insignificantly lower compared with the values in the dry season. Continuous monitoring is recommended.
