The wastewater of a chicken slaughterhouse in the form of rumen contents or gastric contents, excess blood, flesh, fat, and the rinsed water has become a source of environmental pollution. Characteristics of liquid waste generated from industrial activities slaughterhouse varies greatly, filled with relatively high organic matter content and fat solids concentration. The objective of the research is to determine the ability of the anaerobic bio-filter in minimizing total biological oxygen demand (BOD5), chemical oxygen demand (COD) in wastewater slaughterhouse. Samples were taken directly to the tub washing after chicken feathers were plucked. Application of the influent BOD concentration is in milligrams per liter (mg / L) with a value range of 420 mg / L; 400 mg / L; and 380 mg / L. Media used in this research is bio-ball to reduce pollutant loads in soluble BOD5, and COD in wastewater slaughterhouse with anaerobic biofilter dipped in up flow. It can be concluded that it is efficient to remove soluble BOD5, and COD. The least BOD concentrate influet is capable of removing the greatest amount of soluble BOD, and COD. At a concentration of 380mg BOD influent / L, the content of 98.08% dissolved BOD5 and content of 96.21% COD. is successfully removed. © 2006-2016 Asian Research Publishing Network (ARPN).
