Characterization of sewage treatment plant in an emerging territory

Effective sewage management demands continuous evaluation of waste water plants to pick out any potential environmental or health challenges as quickly as possible. One of the cardinal objectives of a sewage treatment plant is to reduce biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solid (TSS). The characterization and evaluation of a waste water treatment plant a developing territory is undertaken. Qualitative research design was adopted for the study and the methodological steps used in the work graphically displayed. The plant achieved its lowest BOD, COD and TSS of 7.7mg/l, 18mg/l and 12mg/l respectively at the effluent in June, 2015. A comparative assessment of the characteristic discharge parameters in relation with standard limits given as 30mg/l, 100mg/l and 30mg/l, for BOD, COD and TSS respectively show that the studied case is operating at safe conditions. A further comparison with the subsisting national effluent benchmarks of 30mg/l, 80mg/l and 30mg/l respectively for BOD, COD and TSS indicate that the sewage plant is within the safe operational ranges prescribed by the prevailing environmental benchmarks.
