Biological treatability of poultry processing plant effluent - a case study

Poultry processing generates strong wastewaters with characteristicsthat may be tailored by appropriate adjustment of the operation. Theorganic content has a residual fraction in the order of 200-400 mg l^-1, depending on the strength of the wastewater. The values of kinetic and stoichiometric constants related to biological treatability are observed to be quite comparable with domestic sewage. Thehydrolysis of slowly biodegradable organics is best described by dual-hydrolysis kinetics with appreciably different rate constants for soluble and particulate components. The experimental results of the study may be used to evaluate the achievable compliance with existing effluent limitations and to define the optimum in-plant operation and wastewater treatment and disposal strategy.
