Gaseous Emissions from Wastewater Facilities

Abstract

A review of the literature published in 2016 on topics relating to gaseous emissions from wastewater facilities is presented. This review is divided into the following sections: odorant emissions from wastewater treatment plants (WWTPs); greenhouse gas (GHG) emissions from WWTPs; gaseous emissions from wastewater collection systems; physiochemical odor/emissions control methods; biological odor/emissions control methods; odor characterization/monitoring; and odor impacts/ risk assessments.

A model for the evaluation of organic compounds emission from aerated liquid surfaces

“…The activated sludge process is commonly used for the treatment of municipal and industrial wastewater. In this process, microorganisms oxidize organic matter to reduce the concentration of pollutants and odour releasing substances such as hydrogen sulphide and various organic compound (Hwang et al 1995, Frechen 2004, Koh and Shaw 2017. The effective operation of the process requires the supply of dissolved oxygen to support the microbial oxidation processes that occur in the liquid phase.…”

Integration of the energy recovery step in municipal wastewater treatment chain: a case study of Moshi municipality, Tanzania

“…Biological method of treating municipal wastewater in most of the developing countries such as Tanzania is mainly done in waste water stabilization ponds (WSP S ) systems which treat waste water naturally (Ho, Van Echelpoel & Goethals, 2017). In anaerobic ponds (AP S ) organic matter contained in wastewaters are decomposed by microorganisms in absence of oxygen to produce mixture of different gases like ammonia, hydrogen sulphide, carbon dioxide and methane (Koh & Shaw, 2017). This mixture is considered as the renewable and sustainable energy source in its right proportion.…”

“…The anaerobic biodegradation of the organic waste contained in the WSP S can release mixture different gases to the atmosphere including ammonia, hydrogen sulphide, carbon dioxide and methane (Fig. 2) (Daelman et al, 2012;Koh & Shaw, 2017). When gases mixture is in their right proportions they are considered as a biofuel.…”
