|Title:||Characterization and removal of odors from refuse material||Authors:||Koe, L.C.C.||Issue Date:||1988||Citation:||Koe, L.C.C. (1988). Characterization and removal of odors from refuse material. Environmental Monitoring and Assessment 10 (1) : 75-84. ScholarBank@NUS Repository.||Abstract:||Odorous gases emitted from refuse wastes were scrubbed through activated carbon columns until odor breakthrough occurred. Refused air samples were collected at the influent and effluent ports of the columns for analysis on a gas chromatograph-mass spectrometric system and for odor determination by dynamic olfactometry. Chromatographic profiles of the gases emitted from refuse material were obtained and volatiles identified included carboxylic acids and some sulphur compounds. Organoleptic tests with a dynamic olfactometer revealed that the odor concentration of refuse air averaged about 50 sou m-3. The adsorption capacities of four commercial grades of activated carbon for refuse odor were evaluated and compared. Results indicated that chemically impregnated activated carbons that are commonly used for odor control at sewerage facilities were less cost effective than non-chemically impregnated carbons.||Source Title:||Environmental Monitoring and Assessment||URI:||http://scholarbank.nus.edu.sg/handle/10635/84749||ISSN:||01676369|
