A pilot-scale rotating biological contractor RBC was used to treat wastewaters from explosives production at Holston Army Ammunition Plant. At hydraulic loadings up to the system maximum of 1.1 galmin-ft2, COD removals of 80 to 90 percent and BOD5 removals of nearly 100 percent were achieved from late spring to mid-autumn, 1985. The RBC was able to accommodate abrupt changes in loading and temperature, but performance degraded substantially with the onset of prolonged cold weather in December 1985. Of the nitramines, only TAX was significantly reduced by RBC treatment. These results generally support earlier RBC studies, which used high-strength synthetic wastewaters.
