Performance Evaluation of Municipal Waste Water Treatment plant in Bangalore

Civil Engineering

India is confronted with a slew of water and wastewater concerns, as well as water-related health risks. Almost 80% of the water used for domestic purposes is returned as wastewater. Untreated wastewater is usually released, which either sinks into the earth as a possible pollutant of ground water or is dumped into the natural drainage system, polluting downstream areas. In most places, sewage treatment plants (STPs) have been built to reduce the total pollutant load on receiving water bodies, hence lowering the degradation of water quality. When poorly treated wastewater with significant levels of contaminants is discharged to surface water or on land, it causes serious environmental problems due to inadequate design, operation, or maintenance of treatment systems. The purpose of this study is to assess the performance efficiency of a waste water treatment facility, namely a sewage treatment plant. The primary water quality indicators, such as Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS), were measured in waste water samples collected at various phases of treatment units (TSS), Oil grease, Total Settleable Solids (TSS), Total Dissolved Solids (TDS), Nutrients (N&P), and Total Settleable Solids (TSS). Each unit's performance effectiveness in removing pollutants was assessed. The plant's overall performance has also been estimated. The collected data were extremely helpful in identifying and correcting operating and maintenance issues, as well as the plant's future expansion to accommodate greater hydraulic and organic loadings
