Performance-based characterization of a contact stabilization process for slaughterhouse wastewater.

This paper evaluates the effluent treatment plant of a slaughterhouse in Hawalli City, Kuwait processing 1100 heads of livestock a day. Results indicated that the proposed process effectively reduces pollution potential of slaughterhouse wastewater. Influent Chemical Oxygen Demand (COD) ranged from 3335 to 7580 mg L(-1), of which approximately 30% were in the form of suspended solids (SS).
