Poultry Slaughterhouse Wastewater Remediation Using a Bio-Delipidation Pre-Treatment Unit Coupled with an Expanded Granular Sludge Bed Reactor

The treatment of poultry slaughterhouse wastewater (PSW) with an Expanded Granular Sludge-Bed Bioreactor (EGSB) is hindered by the washout activated sludge, and difficulties associated operation three-phase separator determination optimum up-flow velocity for sludge-bed fluidization. This results in a poor reactor functionality, thus performance due to pollutants such as fats, oil grease (FOG) PSW being treated. Hydrolyzing FOG content bio-delipidation, enzyme-based agent pre-treatment unit would significantly improve effectiveness primary treating system, i.e., EGSB. In this study, was pre-treated 48 h biological mixture containing bioflocculants bio-delipidation constituents. further treated FOG, total chemical oxygen demand (tCOD) suspended solids (TSS) were determined assess process well observe remedial action combined pre-treatment-EGSB system. An increased efficacy noted whereby tCOD, TSS removal averaged 76%, 88% 87%, respectively. developed intended micro, small medium slaughterhouses.
