Odorous emissions from wastewater treatment systems and treatment facilities affecting quality of life have given local populations reasons to complain for decades. Odor occurring from wastewater treatment plants occurs in entrance, in sludge thickening and digestion, in sludge dewatering units, in dewatered activated sludge conveying, storage and drying phases. The first step in this study has been identified all the potential odor sources in a waste water treatment plant. In this study, the cause of the odor problem of the wastewater treatment plant in Turkey and removal methods have been investigated.
