Blood & Protein Wastewater

Blood and protein residues from slaughtering and processing create some of the highest-strength wastewater in the food industry. Effective capture and recovery can significantly reduce treatment costs while generating valuable by-products.

Extreme BOD Loading

Blood and protein wastewater can reach 10,000-50,000 mg/L BOD, creating significant treatment challenges and costs.

Colour Issues

Blood creates intense coloration that can persist through treatment, requiring specialised colour removal processes.

Value Recovery

Blood and proteins can be recovered for rendering, creating output while reducing treatment load.

Temperature Effects

Hot processing water can coagulate proteins, affecting their separation characteristics and treatability.

Blood & Protein Recovery Systems

Our integrated approach combines blood capture, protein recovery, and wastewater treatment to maximise value recovery while minimising discharge volumes.

DAF Flotation

Dissolved Air Flotation effectively separates blood and protein solids from wastewater, achieving high recovery rates.

  • 85-95% solids capture
  • High-rate clarification
  • Compact footprint

Screw Press Dewatering

High-performance screw presses dewater recovered blood and protein solids for rendering or disposal.

  • 20-30% cake solids
  • Continuous operation
  • Low energy consumption

Chemical Conditioning

Optimised coagulant and polymer dosing improves solids capture and dewatering performance.

  • Enhanced solids capture
  • Improved dewatering
  • Reduced chemical requirements

Blood & Protein Recovery Process

Screening

Preliminary screening removes coarse solids and protects downstream equipment.

Equalization

Flow balancing tank smooths variations in blood and protein loading.

Chemical Conditioning

Coagulant and polymer addition promotes solids aggregation for separation.

DAF Separation

Flotation removes concentrated blood and protein solids from wastewater.

Dewatering

Screw press reduces moisture content for rendering or disposal.

Rendering/Disposal

Recovered material is sent for rendering or proper disposal.
