This research work was embraced to assess the kinetic coefficients values of a suspended growth type batch reactor for the dairy industry wastewater treatment. This examination was done in a research facility batch type arrangement which was comparable to the aeration tank of Effluent Treatment Plant (ETP). Wastewater samples were withdrawn on regular basis to characterize wastewater. Simulated dairy wastewater was made synthetically according to the characterization done which was found the COD of 640 mg/L and ammonium nitrogen concentration of 43 mg/L. Kinetic study was conducted to find kinetic coefficients (Y, K_s , k_d and k).
