A study was conducted to assess the performance of the domestic wastewater treatment plant designed for the New Mangalore Port Trust (NMPT) township, Panambur. The data of raw, aerated and treated wastewater samples were collected for a period of 24 months (January - 1998 to December 1999) with a sampling frequency of one month. The sewage treatment plant is designed to treat an average flow of 1.2 MLD. The treatment scheme is based on extended aeration activated sludge process and consists of bar screens, collection sump, grit channel, aeration tank, secondary clarifier, treated sewage sump and sludge drying beds. The salient design features of the plant, process description, physico-chemical characteristics of sewage at different stages of treatment, sludge and grit are presented. Various parameters were tested in the laboratory and analyzed to assess the performance of the treatment plant. The effluent concentrations revealed that the treatment plant was found to be working quite satisfactorily though the influent wastewater quality was varying considerably. © Enviromedia.
