  • What is slaughterhouse wastewater?
  • Slaughterhouse wastewater (SWW) contains proteins, fats, high organic contents, microbes, and other emerging pollutants (pharmaceutical and veterinary residues). It is important to first characterize the wastewater so that adequate treatment techniques can be employed so that discharge of this wastewater does not negatively impact the environment.
  • What is the main source of organic materials in Slaughterhouse wastewater?
  • The main sources of organic materials in the slaughterhouse wastewater are blood, fat oil and grease, etc. [1,2,5]. The wastewater has a high strength in terms of biochemical oxygen demand, chemical oxygen demand (COD), suspended solids, nitrogen, and phosphorus , compared to domestic wastewaters [2, 7].
  • Why is treatment of Slaughterhouse wastewater necessary?
  • The large quantity water used in the process, as well as the vast volume wastewater generated can make of the water recourses scarce. For this reason, an adequate treatment of slaughterhouses wastewater (SWW) is extremely necessary [ 6 ].
  • Which treatment method is best for slaughterhouse wastewater?
  • Anaerobic treatment of slaughterhouse wastewater is the most preferred option because of its capacities to handle high-strength wastewater with minimal sludge production as compared with aerobic treatment technologies and potential resource recovery in the form of methane.
