Current and Functional Reactor Designs in Poultry Slaughterhouse Wastewater Treatment

Abstract

Poultry slaughterhouse industry consume high volume of portable water and generate large volume of wastewater which contain high Chemical Oxygen demand, Total suspended solids, fats, oil and grease (FOG). In order to mitigate the disposal of raw poultry slaughterhouse wastewater (PSW) effluent, various technologies such as chemical-DAF, electrocoagulation, EGBS and UASB reactors have been used to treat the PSW. However, most of these technologies have operational challenges which range from clogging of reactors, long processing time and low efficiencies. This paper aims to highlight challenges faced during operation of these reactors and also motivate for design improvement to mitigate the deficiency.
