摘要: A continuous flow reactor, inoculated with Aspergillus niger AN400, total volume of 5 L was operated at 29oC, eight hours retention hydraulic time and 150 L.h-1 air rate in order to remove 25 mg.L-1 Congo Red dye from a synthetic wastewater. The feeding the done two phases: Phase I, 0,5 g/L saccharose II, no saccharose. In it possible verify efficiencies organic matter color (mg Pt.L-1) removal 80 ± 16% 82 10%, respectively. efficiency 75 13% 89 7%. higher removals nutrients were achieved by reactor I 25% ammonia, 90% nitrite, 93% nitrate 21% phosphorus. Apparently, presence improved nutrients.
