Biological treatment of high strength ammonia wastewater using a four stage RBC
The objective of the research was to determine the treatability of lignite derived coal gasification wastewater using a four stage rotating biological contractor (RBC). Previous research successfully demonstrated the effectiveness of using a single stage RBC for carbonaceous removal. The four stage RBC was operated to determine whether the additional stages would permit the conversion of ammonia to nitrate. The four stage bench scale RBC system has demonstrated the feasibility of using the RBC process to reduce ammonia levels to less than 100 mg/l and BOD/sub 5/ to less than 30 mg/l. The resistance of the RBC process to upset by shock loading makes the system easier to control and provides a more consistent effluent. 1 ref., 1 fig.
