Gas-chromatography/mass-spectrometry analysis of raw process water from reverse-forward combustion in a tar sand extraction experiment indicated that identifiable compounds were distributed in about equal portions among acid, base, and neutral fractions. The compounds in the neutral fraction were unsaturated, oxygenated methyl cyclohexenyl ketones, methyl-methylcyclohexenyl ketones, acetophenones including methyl-tolyl ketones, lactones, and indanones. Neutral fraction constituents were reduced by about 99% during activated-sludge treatment. The base fraction consisted pyridines, quinolines and their alkane substitutes, and acridines. These compounds were reduced by about 76% during treatment. The acid fraction consisted of carboxylic acids ranging in molecular weight from C/sub 1/ to C/sub 11/, phenols and cresols, and benzoic and toluic acids. These materials were reduced by about 95% through activated-sludge treatment. It was concluded that (1) activated-sludge treatment can reduce soluble organic carbon and chemical oxygen demand by about 90% in the process water and (2) the water is nonmutagenic as defined by the standard Salmonella/Ames test.
