Denitrification path and nur in bulkwater phase of municipal sewer networks using natural wastewater. / Salmah Yatim

In conventional view, Wastewater Treatment Plants (WWTPs) have been considered as stand-alone units, separate from the sewer system. Treatment, which comprises of physical, chemical and biological processes, is assumed to begin when the wastewater arrives at WWTPs. Recent findings established that w...

Solid wastes In conventional view, Wastewater Treatment Plants (WWTPs) have been considered as stand-alone units, separate from the sewer system. Treatment, which comprises of physical, chemical and biological processes, is assumed to begin when the wastewater arrives at WWTPs. Recent findings established that wastewater treatment could occur in sewer.

It is well known that hydrogen sulfide which is the main source of problems related to odor, human health, toxicity and corrosion of piping and pumping system produced under anaerobic conditions. Anaerobic can be suppressed by adding nitrate to the wastewater to change anaerobic to anoxic condition. The purposes of this study are to verify denitrification pathway in bulkwater phase of sewer networks and to determine nitrate utilization rate (NUR) during anoxic transformations of municipal sewer wastewater. This study is basically of experimental works. The samples for this study are taken from a man-hole near the Civil Engineering Laboratory and wastewater treatment plant located at Jalan Ilmu, UiTM Shah Alam. 2 samples i.e., liquid and gas samples were taken periodically.
