Temperature effects on kinetics and economics of slurry-phase biological treatment
- OHM Remediation Services Corp., Findlay, OH (United States)
OHM Remediation Services Corp. conducted bench-, pilot-, and full-scale slurry-phase biological treatment of polycyclic aromatic hydrocarbons (PAHs) present in Resource Conservation and Recovery Act (RCRA)-listed K001 wood-preserving wastes at a Superfund site in Mississippi. As part of an optimization program for the full-scale treatment system, several bench-scale experiments were conducted to determine the effect of operating temperature on biodegradation of the PAHs present in the wastes. Experiments were conducted in 6.5-L bench-scale slurry reactors to determine the effect of various operating temperatures on PAH biodegradation. The bench-scale operating temperatures were selected based on the range of operating temperatures observed in the full-scale treatment system. PAH degradation in the reactors was monitored by both total PAH concentration and by individual PAH concentrations in the slurry. Biodegradation rates at various temperatures from the 750,000-L slurry reactors in the full-scale treatment system were compared to the data obtained from the bench-scale reactors. An engineering-economic analysis compared the cost of heating the full-scale reactors during periods of low ambient temperatures versus extending operating time to achieve treatment criteria.
