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.
