Abstract

The sewer is an integral part of the urban wastewater system that comprises of the sewer, the wastewater treatment plant and the local receiving waters. The sewer is a reactor for microbial changes of the wastewater during transport, affecting the quality of the wastewater and thereby the successive treatment processes or receiving water impacts during combined sewer overflow. This report presents the methodology and results of studies on anoxic processes, namely denitrification, in the bulk water phase of wastewater as it occurs in sewers. Since anoxic conditions do not normally exist in sewer, sodium nitrite is added to the sample to induce the anoxic condition. Tests were conducted on 7 different wastewater samples taken from two locations, namely, the wastewater treatment plant (WWTP) at Section 23, Shall Alam and WWTP located at Jalan Ilmu, UiTM, Shah Alam. Tests were performed using batch reactors to measure denitrification rate under conditions of excess electron donor and limited electron acceptor. Concentrations of electron acceptors i.e., nitrate and nitrite were determined using Ion Chromatography 790 COM. This report also presents the results of studies on half saturation constants for nitrite, KNO2, in raw wastewater. The average value of KNO2, determined from experiments conducted on 7 different wastewater samples were found to be 0.64jp units.
