Protein-Rich Wastewater Characteristics

Poultry processing generates wastewater with exceptionally high protein concentrations from blood, tissue residues, and processing water. These proteins create significant treatment challenges including high BOD, foaming, and sludge production.

High BOD Loading

Protein-rich wastewater can reach 3,000-8,000 mg/L BOD, requiring robust advanced biological treatment systems engineered for high-strength industrial waste.

Foaming Issues

Proteins and surfactants from cleaning create persistent foam in aeration basins, requiring specialised antifoam systems and process controls.

Sludge Production

High protein content generates substantial biological sludge, necessitating efficient dewatering systems and disposal strategies.

Temperature Sensitivity

Hot processing water (40-60°C) can shock biological systems, requiring temperature management or specialised microbial cultures.

Protein Treatment Technologies

Our integrated treatment approach combines physical solid-liquid separation, biological degradation, and advanced clarification to handle high-protein poultry wastewater effectively.

Primary Screening

Rotary drum screens and static curved screens remove feathers, tissue, and coarse solids before advanced biological treatment, protecting downstream equipment.

  • Removes particles >0.5mm
  • Reduces organic loading by 15-25%
  • Continuous self-cleaning operation

DAF Flotation

Dissolved Air Flotation removes suspended proteins and fats through micro-bubble attachment, achieving 80-95% TSS reduction.

  • Protein recovery for rendering
  • High-rate clarification
  • Compact footprint design

Extended Aeration MBBR

Moving Bed Biofilm Reactor with extended aeration provides stable advanced biological treatment for high-protein wastewater with excellent sludge settling.

  • Handles BOD up to 5,000 mg/L
  • Resistant to shock loads
  • Low sludge volume index

Treatment Process Flow

Pre-Screening

Rotary drum screens remove feathers and coarse solids (>2mm) to protect downstream equipment.

Flow Equalization

Balancing tank smooths flow and loading variations from batch processing operations.

DAF Clarification

Dissolved Air Flotation removes suspended proteins and fats with polymer coagulation.

Biological Treatment

Extended aeration MBBR degrades dissolved proteins and reduces BOD by 95%+.

Secondary Clarification

Lamella clarifier separates biological sludge with high efficiency and small footprint.

Sludge Dewatering

Screw press reduces sludge volume by 85-90% for efficient disposal.
