Characterization and Assessment of Treatability of Wastewater Generated in Amman Slaughterhouse

Ameen Sarairah, Ahmad Jamrah

Abstract


Slaughterhouse industry can result in serious environmental pollution. Amman slaughterhouse is considered the largest one in the country and consumes more than 400m3/day. This study aims to characterize slaughterhouse wastewater generated in Amman, and assessing various suitability of biological treatment and economic feasibility of wastewater reuse. Composite wastewater samples were collected and analyzed from Amman slaughterhouse in the period of December 2006 to July 2007. Results of the study indicated the presence of diurnal differences between the characteristics of the wastewater between summer and winter. Amman slaughterhouse wastewater is classified as strong wastewater in terms of its content of COD and BOD5. The ratio of COD/BOD5 indicates applicability of biological treatment. The study also concluded that the organic and nitrogen contents of the slaughterhouse wastewater are associated significantly with suspended solids indicating that anaerobic biological treatment could be more efficient for the treatment of this type of wastewater. The study also showed that direct reuse of slaughterhouse wastewater is acceptable in terms of most of its inorganic content while direct reuse is not acceptable in terms of its organic content. Finally, yearly cost-benefit analysis related to the treatment and reuse of Amman slaughterhouse wastewater shows net earning resulting from proper management of this wastewater.
