Transformation of nitrogen and sulphur compounds in municipal wastewater under changing anoxic/anaerobic conditions / Muhammad Hazrin Yacob

The formation of hydrogen sulphide in the sewer networks is caused by anaerobic processes. It leads to various problems namely corrosion, health risk and odor. Anoxic processes are proven effective in previous studies in controlling its formation. However the lack of fundamental knowledge on the pat...
