| It is important to burn the air toxics and harmful gases which come from water and wastewater treatment processes. In common practice, instead of natural gas, digester gas is used for economical reasons. This burning process takes place in the Regenerative Thermal Oxidizer (RTO).;The current research was conducted to identify if there exists any differences between natural gas and digester gas in outlet emission. The location of the experiment was at Morris Forman Wastewater Treatment Plant of Metropolitan Sewer District (MSD) of Jefferson County, Kentucky, USA. In this experiment, the RTO was run in two cases: one fueling by digester gas and next fueling by natural gas; then samples were obtained from a sampling port during each case. The captured samples were analyzed in the laboratory at the University of Louisville, Kentucky. The resulted data from these two cases showed that there are not much emission differences between these two fuels. Therefore, use of digester gas instead of natural gas is an economical move without causing any harmful emission. |
