In this study, ultrasonic treatment of baker’s yeast effluent was investigated in an ultrasonic homogenizer emitting waves at 20 kHz. The SnO₂ /TiO₂  composites were used as a sonocatalyst to assist the sonication process. Decolorization and chemical oxygen demand (COD) removal of baker’s yeast effluent with ultrasonic irradiation was examined. The effect of the composite preparation method, the molar ratio of SnO₂ /TiO₂  mixing time while the composite was prepared, the calcination temperature and time, the catalyst amount were investigated. The decolorization was higher at a 4:1 molar ratio of the SnO₂ /TiO₂  composite prepared by using an ultrasonic probe and 6 min ultrasonic irradiation time. The decolorization increased, with an increase in the calcination temperature. The optimum calcination time was 60 min and catalyst amount was 0.2 g/l. According to the results, decolorization rate was 26.63% using this composite. There was no COD removal at the studied conditions.
