Wastewater Treatment Plant

Wastewater is generated mainly due to the activities of slaughtering animals and cleaning equipment and work areas. These are some of the activities in which wastewater is produced:

Stabling: When the animals to be slaughtered are received, they are placed in stables, where fecal waste and other remains are produced.

Slaughter of animals: During the slaughter process, water is used to wash animals. This water may contain traces of blood, fat and other biological materials.

Washing of equipment and work areas: After slaughter and butchering of animals, regular cleaning of equipment and utensils is required to maintain hygienic standards. This involves the use of water to rinse utensils, work tables, floors and other areas.

Processing of animal by-products: Slaughterhouses may process animal by-products such as viscera, bones, fats and other tissues. During these operations, wastewater may be generated due to the washing and cleaning of these materials.

Treatment of skins: In some slaughterhouses, animal skins may undergo tanning and treatment processes for subsequent use in the leather industry. These processes involve the use of water and chemicals, which can result in wastewater containing pollutants. In these cases, it is preferable to separate these effluents from the rest and treat them specifically.

There are different options for the disposal of slaughterhouse wastewater:
  • Direct discharge to the environment.
  • Discharge to a municipal wastewater treatment plant.
  • Reuse of treated water in individual areas.

Each option requires different treatment standards, with direct discharge and reuse requiring the most stringent standards, as industrial or municipal wastewater treatment plants have effluent treatment lines. As a guideline value for the flow of water, an average consumption of 5 liters of water for each kg of weight of the animal to be slaughtered is estimated.
