The present study was undertaken to evaluate the kinetic coefficients of a suspended growth batch reactor for biological treatment of dairy effluent. An experimental study was performed in the Environmental Biotechnology laboratory, Jadavpur University, to evaluate kinetic coefficients for designing an activated sludge process. Samples of dairy plant were withdrawn on regular interval to establish statistically mean values of wastewater characteristics. A simulated sample was prepared synthetically on the basis of statistically derived real life effluent characteristic with average COD concentration of 700 mg/L. A time-concentration profile was recorded in terms of pH, MLSS and COD removal for an initial MLSS concentration of 1500 mg/L. Initial pH was set at 7.15 and was observed as 7.65 after 48 h. The maximum COD removal of 77.45% was achieved after 48 h retention time. Kinetic coefficients were evaluated on the basis of batch studies and the values of yield coefficient (Y), half velocity constant (Ks), endogenous decay constant (kd) and substrate removal rate coefficient (k) were obtained to be 0.568 mg MLSS/mg COD, 72.134 mg/L, 0.031 day−1 and 8.84 day−1 respectively. These kinetic results are found to corroborate other researchers’ findings and would useful for designing an activated sludge unit for treating dairy wastewater.
