SLAUGHTERHOUSES AND MEATPACKING INDUSTRY
Slaughterhouses and meatpacking companies waste water comes from washing some meat-processing facilities. The amount of waste water that is required to undergo a purification treatment may change according to the business size, the kind of animals and last, but not least, the amount of water used for washing the previous mentioned facilities. The average sewage from a slaughterhouse contains high concentration of organic substance and, most of all, ammoniacal nitrogen from animals urine, but it does not have to contain animals blood, which has to be handed over to specialized waste-disposal companies.
The purification plant has to be dimensioned to the effluent final receiving body, and has to guarantee an abatement level of the pollutants complying with seasonal ups and downs.
To be as effective as possible, any purification process targeting slaughterhouses and meatpacking has to arrange: a screening automatic system, an equalization stage – which is required to balance the fluctuations in the pollutants concentration – and one or more oxidation-nitrification-denitrification stages with a view to the abatement of any organic compound, including ammoniacal nitrogen. The plant is custom built from DEPURECO’s engineers who conveniently draw its layout in order to take just the room strictly required to allow maintenance operations as well as the plant management.
STANDARD TREATMENT PROCESS:
- Fine screening
- Aerated homogenization
- Nitrification (once or more)
- Excess sludge aerobic stabilization
- Excess sludge dehydration
DEPURECO’S PLANTS TARGETING SLAUGHTERHOUSES:
- Guarantee flexibility (ability to adapt to predictable seasonal ups and downs)
- Require users to handle low operational costs (due to the implementation of several treatment steps)
- Accomplish full abatement of organic compounds and nitrogen
- Provide treatments either preparatory or integrative to the biological one
The plant size suits the structure operating parameters, that DEPURECO checks in advance. Due to its own 40 years experience, DEPURECO is able to come up with the most fitting solution to meet the expected purification standards.
