Abstract
A standard odor unit is defined, and provides the basis for quantitative measurement of odor concentrations of sewage gases at wastewater facilities. Dual observations of H2S concentrations and sewage odor concentrations using a commercially available H2S monitor and a dynamic olfactometer, respectively, indicate that, despite high odor variability, the central trend of the relationship is (a) approximately linear for sewage with significant proportions of industrial wastes, and (b) exponential for domestic-type wastewater. Odor contributions attributable to H2S are found to be apparently subdued by other sewage gas substances.
