Abstract |
Wastewater at SOHIO's Toledo refinery was sampled every four hours for four successive days in December 1976. Effluents from the full-scale system (dissolved-air-flotation (DAF) unit and final clarifier for the activated-sludge unit) and an add-on pilot-scale unit (mixed-media filter and activated-carbon columns) were sampled for analysis of common wastewater parameters and trace organic compounds. Grab samples taken every four hours were composited daily. Organics were isolated into acid, base, and neutral fractions. Four-day composites of these daily extracts were analyzed by capillary-column gas chromatography/mass spectrometry. Some 304 compounds were identified in the neutral fraction of the DAF effluent and removal of these organics by the activated-sludge and add-on treatment units was estimated. Numerous data for the approximate concentration of organic compounds are presented. Common wastewater parameters are also presented for comparison to specific organics concentration data. The activated-sludge unit removed aromatic compounds better than it did nonaromatics whereas the activated-carbon unit was better at removal of nonaromatic compounds. Average percentage removal of those organics present in the DAF effluent was greater than 99 percent (activated sludge), approximately 0 percent (mixed-media filter), and less than 1 percent (activated carbon). Of the approximately 1 percent of trace organics remaining in the final-clarifier effluent, 81 percent (by weight) were removed by the activated carbon. Because of variations in extraction efficiencies, amount of sample injected, losses on the GC column and transfer lines, and other sources of error, these are only approximate removal estimates.
