Biological treatability of poultry processing plant effluent - A case study

Poultry processing generates strong wastewaters with characteristics that m ay be tailored by appropriate adjustment of the operation. The organic cont ent has a residual fraction in the order of 200-400 mgl(-1), depending on t he strength of the wastewater. The values of kinetic and stoichiometric con stants related to biological treatability are observed to be quite comparab le with domestic sewage. The hydrolysis of slowly biodegradable organics is best described by dual-hydrolysis kinetics with appreciably different rare constants for soluble and particulate components. The experimental results of the study may be used to evaluate the achievable compliance with existi ng effluent limitations and to define the optimum in-plant operation and wa stewater treatment and disposal strategy.
