In Allahabad city, Wastewater Treatment Plant (WTP) is based on activated sludge process with surface+aerator and air+diffuser on the riverside of GANGA, Naini, Allahabad, U.P, India. This STP is constructed and designed with an aim to manage wastewater so as to minimize disease-causing organisms, organic matter, solids, nutrients, and other pollutants. It was examined from the performance study that efficiency of the treatment plant was good enough with respect to removal of TDS in opposite to the reduction in other parameters like, TSS, BOD and COD. In Naini plant, BOD, COD and TSS removal efficiency of three month were, 67.81, 62.59 and 62.16% respectively. The diplomatic order of reduction efficiency was BOD < TSS < COD STP. In addition to this, the disadvantages associated with the maintenance and operation of waste water treatment plant is examined. The research work presents the results of the evaluation carried out for the efficiency analysis of STP based on activated sludge process with surface aerator and air diffuser located in Allahabad for handling and treating the municipal wastewater.
