Title

TREATMENT OF POULTRY SLAUGHTERHOUSE WASTEWATER IN UPFLOW ANAEROBIC FILTER UNDER LOW UPFLOW VELOCITY

Pages

  149-158

Abstract

 The wastewater discharged by poultry slaughterhouse industries are characterized mainly by high biochemical oxygen demand, high suspended solids and complex mixture of fats, proteins and fibers requiring systematic treatment prior to disposal. In this study, the performance of an upflow anaerobic filter reactor for treating Indian poultry slaughterhouse wastewater under low upflow velocity of 1.38 m/day at MESOPHILIC TEMPERATURE (29-35°C) was investigated. The reactor was inoculated with anaerobic non-GRANULAR SLUDGE from an anaerobic reactor treating the poultry slaughterhouse wastewater. The reactor took 147 days for complete start-up with removal efficiencies of total chemical oxygen demand and soluble chemical oxygen demand of 70 and 79 % respectively. The maximum total chemical oxygen demand removal efficiency of 78 % was achieved at an organic loading rate of 10.05 kg/m3/day and at an hydraulic retention time of 12 h. The average methane content varied between 46 and 56 % and METHANE YIELD at maximum removal efficiency was 0.24 m3 CH4 /kg CODremoved.day. Sludge granules of 1-2 mm were observed in between the packing media. SCANNING ELECTRON MICROSCOPE analysis revealed that sludge granules are composed of clumps of METHANOSARCINA clustered with less intertwined METHANOSAETA fibre of granules. The lower velocity used in this study has achieved better performance of the reactor by creating active microbial formation with stable pH upto an organic loading rate of 14.3 kg/m3/day. This has proved that the poultry slaughterhouse wastewater can be treated using anaerobic filter reactor under low upflow velocity.
