STUDY ON REMOVAL OF ORGANIC POLLUTANTS USING THE EXPANDED GRANULAR SLUDGE BED REACTORVIJAYBABU S. AND ASHA B.
Slaughterhouse wastewater contains various and high amounts of organic matter, which contributes paunch, feces, grease, fat, and lard, undigested foods, blood, suspended material, urine, loose meat, soluble proteins, excrement, manure, grit and colloidal particles. The purpose of this research work is to investigate the feasibility study of EGSBR for treating slaughter house wastewater with the impact of HRT with respect to the organic removal efficiency. The experimental model was run with six average different ranges of influent COD of 1752, 1744, 1820, 2264, 2768, and 3176 mg/L. The maximum efficient organic removal was attained at 90.17% with a HRT of 4 days at an OLR of 0.081Kg COD/m3.day. The study was run at mesophilic range of temperature for efficient growth of organism. The slaughter house wastewater was observed under various magnifications in a scanning microscopy. The organism responsible for digestion was identified as Bacillus haikouensis, which is a gram-positive and rod shaped bacteria.
