To Examine Efficiency of Sequential Batch Reactor to Treat Domestic Wastewater

Abstract: The Study aims to examine operation effectiveness of Sequential Batch Reactor (SBR) of wastewater treatment plant in India. Sewage wastewater consists umpteen of chemical pollutants, which can be measured by chemical parameters such as Chemical Oxygen Demand (COD) and Total suspended Solid that, lead to Environmental pollution, if discharge without proper treatment. The correlation between COD and TSS-VSS removal was explored using the six on-plant SBRs, receiving medium strength domestic sewage. Samples were collected from Inlet channel and outlet channel of the Sequential Batch Reactor (SBR). Composite samples were collected for period of 15 Days and experiment of Chemical Oxygen Demand (COD) and Total Suspended Solid and Volatile Suspended Solid (TSS-VSS) were performed by Standard Methods mentioned in APHA. Result of experiments performed express that, average COD and TSS in Inlet wastewater (Influent) are 260 mg/L and 180 mg/L respectively and average COD and TSS of Effluent are 29.4mg/L and 6.2 mg/L respectively. Reduction in COD and TSS is 85-87 % and 85-90% respectively. This preliminary study shows that SBR are potential, a feasible for treatment of domestic wastewater.
