Slaughterhouse wastewaters are considered as highly polluted and very harmful to public health and environment. Therefore, slaughterhouse wastewater must undergo efficient treatment before it is discharged to the sewer line or water bodies. The main objective of this paper is to study the physio-chemical and biological characteristics of the slaughterhouse effluent in local abattoir located at Khartoum state named Al Sahafa Abattoir. In this study we carried out the following tests pH, TDS, Temperature, TSS, BOD5, COD, NH3, Total Phosphorus, TKN, Total coliform. Between August 2019 and September 2019, composite samples were collected from Al Sahafa slaughterhouse. The composite samples were collected two litres every hour for five hours to make them more representative. Following the standards methods of sampling all samples were collected in the morning or early afternoon. The results showed that Al Sahafa slaughterhouse waste water is considered as strong wastewater which has to undergo a proper treatment before being disposed of. The COD/BOD ratio is 1.5, which indicates applicability of biological treatment. The results also shows this effluent cannot be reused or dispose to the water bodies because it does not comply with the Sudan Local order 1970 or Khartoum state law 2008. To design a cost effective treatment unit to reuse or dispose of these effluent, blood capturing unit at the inlet of the slaughtering process must be installed in order to reduce the organic load.
