Wastewater Treatment in Meat Processing

Abattoirs and the meat poultry and fish processing industries produce a huge amount of wastewater that is highly polluted with organic substances — containing blood and dissolved proteins.

Wastewater in Meat Processing Enterprises

The whole chain from cattle delivery, slaughtering and processing to the final cleaning is subject to strict hygiene regulations as are all processes in the food industry. That is why large amounts of wastewater accrue that is highly polluted with organic substances — containing blood and 

dissolved proteins, fat, straw, sawdust and residues of animal excrements. If this wastewater cannot be disposed fast and reliably, significant odour nuisance, germs and insect attacks, threatens the plant.

Our Solutions for Industrial Meat Processing

DAS Environmental Expert offers suitable processes for the treatment of wastewater highly polluted with organic substances. The wastewater used for cleaning the cattle vehicles runs through a mechanical deposition and is collected with the wastewater from the slaughterhouse in a mixing and homogenization container. Subsequently, it is lead to a biological treatment for nitrification and COD reduction. This is a highly energy-efficient technology that helps to reduce operation costs. With DAS plants the wastewater can be biologically treated to the extend that even a direct discharge compliant to all legal limits is possible.

Advantages of Biological Wastewater Treatment

Especially abattoirs have to deal with unpleasant smells due to the accrual of ammonia and hydrogen sulphide as well as the accumulation of solids from deposition. Oftentimes this leads to complaints from residents and the formation of action groups targeting the companies. Therefore, meat and poultry processing industries benefit from the technology of DAS Environmental Expert since its biological treatment is a completely closed system without any open basins. The systems are based on modules and can be integrated in the process. The plants can easily be extended and packed up and moved when changing the production site. The latter is particularly interesting for growth-oriented companies, especially in emerging nations.
