The effect of the sludge recycle ratio in an activated sludge system for the treatment of Amols Industrial Park wastewater



The effect of the sludge recycle ratio in an activated sludge system for the treatment of Amols Industrial Park wastewater



Chemical Industry & Chemical Engineering Quarterly: 3, 173-180



An activated sludge aeration tank and a sedimentation basin were used to treat Amol's industrial park effluents originating from all industrial units. A continuous system was implemented and the kinetic parameters were measured. The parameters such as rate constant, substrate utilization rate constant, yield and decay coefficient were 2.12 d<sup>-1</sup>, 232.4 mg l<sup>-1</sup>, 0.33 g/g of substrate and 0.096 d<sup>-1</sup>, respectively.
