The winemaking is a seasonal activity, for this reason generates, for a year, wastewaters with significant differences in terms of volume and composition, having different biodegradability. Initially, in this dissertation was studied the degradation of a wastewater, from the 2nd racking, an aerobic system with different quantities of biomass, where it was obtained efficiencies of removal of COD of around 83%, 78% and 73% for the biomass volumes of the 1,25; 10 and 20 ml. Later, it was studied the degradation of a synthetic wastewater, in the same treatment system, with volumes of biomass of 10 and 20 ml, where it was found that 10 ml of biomass was the ideal quantity (based on the efficiency of removal of COD). The same aerobic system was applied, to the synthetic wastewater, to different temperatures (20, 25 e 30 ºC), noting that the temperatures of 25 ºC and 30 ºC had greater removal of COD (about 93% and 89%, respectively) and polyphenols (about 72% and 70%, respectively). For the temperatures studied, was determinate the kinetics of degradation (obtaining higher k to higher temperatures), where it was found that in higher temperatures is obtained more biodegradability. Determining the mathematical relation between the removal of COD and polyphenols, it was found that the temperatures of 25 and 30 ºC represent better this relation, with significant coefficients of determination for α=0,001.
