Sewage Treatment Plants (STP), Effluent Treatment Plants (ETP) located near residential or commercial areas, including Apartment building, office buildings etc., can be subject to community frictions and/or legal issues if these facilities produce unpleasant odours. In the modern world of wastewater treatment and STP, control of odors has moved from an afterthought to a primary design consideration for most collection and treatment facilities. As development encroaches on our facilities and our new neighbors become less tolerant of nuisance odors. Most odor problems occur in the collection system, in primary treatment facilities and in solids handling facilities. The following compounds are associated with bad odors: mercaptans, skatoles, indoles, inorganic acids, aldehydes, ketones and organic compounds containing nitrogen or sulfur atoms. These compounds can originate from the anaerobic decomposition of compounds with a high molecular weight, especially proteins. These are recognized as being among the causes of bad-smelling odors at the outlet of sewer lines and in treatment plants in general. Among the inorganic compounds, ammonia and hydrogen sulde are considered to be the main causes of odor when the sewage comes from mainly households. The presence of hydrogen sulfide is caused by a reducing environment, i.e. characterized by low values of the oxidation-reduction potential. The odors associated with collection systems and primary treatment facilities are generated as a result of an anaerobic or septic condition. This condition occurs when oxygen transfer to the wastewater is limited. In the anaerobic state, the microbes present in the wastewater have no dissolved oxygen available for respiration. This allows microbes known as sulfate-reducing bacteria to thrive. These bacteria utilize the sulfate ion (SO4-) that is naturally abundant in most waters as an oxygen source for respiration. The by-product of this activity is hydrogen sulde (H2S). This by-product has a low solubility in the wastewater and a strong, offensive, rotten-egg odor
