Poultry processing wastewater is high in BOD and COD, rich in fats, oils and grease, and carries solids such as feathers, tissue and blood along with a significant nitrogen load. After effective solids and FOG removal, MBBR provides reliable biological carbon removal and nitrification, with the fixed biofilm absorbing the variability of processing shifts.
Solids, FOG and Nitrogen
Fine screening captures feathers and tissue, and dissolved air flotation removes FOG and fine solids before the biological stage. Blood and proteins give a high nitrogen load, so nitrification is typically designed in, with denitrification where total nitrogen is limited. High BOD makes aeration a central design factor, and equalisation smooths the shift-based load pattern.
With this pretreatment in place, a staged MBBR delivers dependable carbon and nitrogen treatment for poultry plants.
Poultry Processing Design Context (indicative literature ranges — confirm per project)
| Parameter | Typical Value | Unit | Notes |
|---|---|---|---|
| Dominant load | high BOD + N | — | Blood, proteins, fat |
| Solids | fine screening | — | Feathers, tissue |
| FOG | reduce upstream | — | DAF |
| Nitrogen | nitrification | — | Denitrification if TN limited |
Related to Meat and Slaughterhouse Duty
Poultry processing shares much with meat processing and slaughterhouse effluents — high organics, FOG and nitrogen — and uses the same overall approach: strong pretreatment followed by a staged MBBR for carbon removal and nitrogen treatment.
