The objective of this research was to determine the treatability of University of North Dakota Energy Research Centers (UNDERC's) and Great Plains' coal gasification wastewaters using a bench scale four stage rotating biological contactor (RBC). The treatability testing included an evaluation of organic removal rates in the first stage and the overall rates in the last three stages using the Stover-Kincannon model. Nitrification was evaluated at various loading rates. Stage 1 accounted for most of the removal of alcohols, fatty acids, phenol, and thiocyanate from both UNDERC stripped gas liquor (SGL) and for alcohols and fatty acid removal from the Great Plains (GP) SGL. The 2, 3 and 4 stages accomplished very little additional organic removal in either system. Biodegradable organic removals remained high in the first stage of the GP SGL test run despite anaerobic conditions in the first stage. 5 refs., 12 figs., 6 tabs.
