Description:
The report gives results of an examination of the potential for toxic organic emissions from synfuels wastewater treatment systems. The synthetic fuels facilities examined were coal gasification, direct and indirect coal liquefaction, shale oil, by-product coke, and associated petrochemical products. A literature survey was performed to assess the fate of organic priority pollutants during wastewater treatment. Pollutants in the volatile, base-neutral, and acid-extractable fractions were examined in order to assess their potential for volatilization during waste-water treatment. Compounds found to contribute organic emissions during waste-water storage and treatment were in the volatile fraction (e.g., benzene, toluene) and the base-neutral fraction (e.g., polynuclear aromatic hydrocarbons). Acid extractables (e.g., phenol) also present in synfuels wastewaters are rarely stripped or volatilized from wastewater stored in impoundments or during activated sludge treatment.
