In the processes of industrialization of cassava flour (Minihot esculenta), there is the generation of an effluent called manipueira, which requires treatment before being released into the water body. The objective of this work was to evaluate the efficiency of effluent degradation by an anaerobic reactor, using as substrate, manipueira of a flour producing industry, and, as inoculum, two distinct sludges, one from an anaerobic reactor of ascending flow (RAFA) of domestic sewage treatment plant, and another from the activated sludge system of effluent treatment of a grain producing industry. The efficiency of the process was evaluated by the physicochemical parameters: COD, BOD, total solids (TS), total volatile solids (STV), fixed total solids (STF), pH, turbidity and cyanide. Throughout the treatment there was a significant removal of Cyanide in the effluent, that is, one of the major problems of the effluent can be solved effectively via anaerobic treatment.
