Gaseous Emissions from Wastewater Facilities

Abstract

This review presents the research and development activities in areas relevant to gaseous emissions from wastewater facilities. Specific areas that are addressed include detection, modeling and control of gaseous emissions from wastewater facilities. Tansel et al. (2004) provided a review of the new developments and research findings on measurement, modeling and control of wastewater emissions published in 2003. In 2004, there was also a significant amount of research activity in development of sensors for measurement of volatile compounds, experimental and modeling studies with biofilters, identification and removal of organic compounds in odorous emissions. HISTORICAL PERSPECTIVES AND REGULATORY COMPLIANCE Longhurst (2004) reviewed the historical aspects of the odor regulations. There is historical evidence of smell problems due to wastewater. Odor from the highly polluted Thames River was so offensive that by the 1850s the Houses of Parliament could no longer function properly. Sir Joseph Bazalgette's contribution, as the chief engineer at the time, was significant in achieving health benefits, disease control and improvements in river ecology. Shi et al. (2004a) also addressed the historical aspects of the

“…odor and gas sensors; sources; control methods; modeling; odor case studies; physicochemical treatment; and biofilters and biotrickling filters. Tansel et al (2005) Quantification and Measurement Pratt et al (2005) conducted concurrent field measurements of 10 volatile organic compounds (VOCs) using passive diffusion-based organic vapor monitors and the U.S. Federal Reference Method, which comprises active monitoring with stainless steel canisters. Ambient concentrations of most VOCs measured by both methods were low compared to those of other large metropolitan areas.…”

“…Intensity is the relative measure of the perceived concentration (TCEQ, 2007). How odors are processed, at the behavioral and neural levels, depends on past experiences, current environmental conditions, and psychological and physical state of the individuals (Tansel et al, 2004(Tansel et al, , 2005(Tansel et al, , 2006. Both organic and inorganic sulfur compounds are the primary cause for the odor nature of landfill gas.…”
