Poultry kill and processing
The poultry plant processes 400.000 birds per day, generating 8.706 cubic meters of wastewater laden with proteins, feathers, offal, and bone.
Preliminary screens remove the coarse solids while the rest of the emulsified oils, fats, and proteins are sent to a DAF system for recovery.
Two DAF units separate solids from the water and send them to recovered product coookers where they are concentrated into an oily product which is sold to a renderer.
DAF effluent is biologically treated in a 3.785 m³ aeration basin.
A third DAF unit is used to separate biomass and remove TP from the biological treatment system. Effluent from this DAF meets the requirements for discharge to a local waterway.
