Pesticides have been used in the fight against various pests to increase crop growth in our country and the world. In recent years, high concentrations of toxic and detection of carcinogenic pesticides indicates that these substances are transported to groundwater and pollute water resources. N- (phosphonomethyl) glycine are also used in large quantities. In this study, the optimization of anaerobic treatment of N- (phosphonomethyl) glycine was investigated by applying a statistical-based experimental design. Full factorial trials different initial pesticide concentrations and cosubstrate type were established, making up 9 different experimental setups. Trials were performed in 2 replicates. The experiments were carried out in Oxitop C bottles with stirring at a working volume of 200 mL. The pH was adjusted to 7 ± 0.2. Trials were performed at 35oC for 30 days. At the end of the process, the removal of the trials according to the input and output COD and pesticide values were examined. As a result, the most efficient COD removal was achieved 98,96 % when pesticide concentration of 5 mg L-1 and glucose as cosubstrate were used. The highest pesticide removal was found to be 74,83% when pesticide concentration of 25 mg L-1 and glucose was used as cosubstrate.
