    The dairy industry has a prominent role in the Brazilian scenario, lacking alternatives that combine a good cost / benefit ratio in the management of its effluents. Thus, the objective of this work was to experimentally analyze the biological filter (BF) with two different media, sugar cane bagasse and wood sawdust, in the biological treatment of dairy effluent, in order to evaluate the effectiveness of the treatment and to identify which of the materials is more efficient. Analyzes of pH, BOD, turbidity, total solids, sediment solids, total dissolved solids, electrical conductivity (EC), nitrogen and phosphorus were performed. There were superior results of removal of BOD, nitrogen and turbidity for the filter filled with wood sawdust. The bagasse filter presented better results on average in the reduction of phosphorus concentration and total solids, which are 91.7% and 59.8, respectively. The reduction of TDS concentration and EC reduction, both filters demonstrated equivalence. The results of sediment solids indicate the need to implement the secondary settler to the system. It is recommended to use FB filled with wood sawdust for treatment of dairy wastewater.
