Slaughterhouse Waste Management

Slaughterhouse Waste Management

The primary focus in slaughterhouse wastewater is to reduce the BOD/COD, bloodstream, and ammonia levels in the discharge released into the main sewers. Emvees offers an economical and sustainable solution that reduces organic waste and odor. Additionally, our clients have the option of reusing the discharge water after treatment.

The primary process to reduce the organic load requires the following mode of action:
  • Removal of Ammonia utilising Bacteriological Cultures that digest the ammonia.
  • Oxidation of organics in the water using the Venturi Ozone generation system. This coagulates the blood and organic particulates.
  • The discharge will then enter a micro DAF unit, which will remove the coagulation and deposit it into a feed system for the BTD.
Solid Process:

The coagulation along with the offell (body parts) will be deposited in a hopper, shredded, and finally fed into a Bio Thermic Digester (BTD) unit, which will consume everything, except large bones and horns. The residue, which forms barely 5% of the original waste, will be collected in a collection cart to be used as soil conditioner.

Liquid process:

The liquid from the macro DAF unit will continue into an aerated Bio-reactor system where bio stimulant will be added at 150ml per day. The Bio-reactor will oxygenate the liquid and create optimum conditions for bacteria to reduce the BOD/COD level (by over 80%) within 24 hours. The liquid will either be pumped into the treated water tanks before discharge to municipal sewer, or sent for downstream treatment into UF followed by RO.

Odour control in slaughter:

Emvees specializes in the installation of two or three timed air stream units that neutralize the ammonia odour from the slaughter area. This is done at minimal cost and provides a better environment for staff and visitors to the site.
