Fat & Grease Management

Animal fats and tallow from slaughtering and processing operations create significant wastewater challenges. Effective separation and recovery can generate output while preventing costly operational issues.

Fat Buildup Issues

Fats can accumulate in pipes, tanks, and equipment, causing blockages and operational problems.

Emulsified Fats

Hot water and detergents can emulsify fats, making separation more challenging.

Value Recovery

Recovered tallow can be sold for rendering, biodiesel, or other applications.

Temperature Dependency

Fat separation efficiency depends heavily on temperature management.

Fat Separation & Recovery

Our fat recovery systems use temperature-controlled separation and DAF technology to maximise tallow recovery while minimising discharge volumes.

DAF Flotation

Dissolved Air Flotation effectively separates both free and emulsified fats from wastewater streams.

  • 95%+ fat removal efficiency
  • Handles emulsified fats
  • High-rate separation

Temperature Control

Heated separation tanks maintain optimal temperature for fat coalescence and separation.

  • 60-70°C optimal range
  • Insulated tank design
  • Energy-efficient heating

Gravity Separation

API separators and tilted plate separators provide primary fat removal before DAF.

  • No energy required
  • Large capacity handling
  • Simple operation

Fat Recovery Process

Screening

Remove solids that can interfere with fat separation processes.

Heating

Wastewater is heated to 60-70°C to melt and coalesce fat particles.

Gravity Separation

API separator removes free-floating fats through gravity separation.

DAF Flotation

Flotation removes emulsified and fine fat droplets from wastewater.

Skimming

Automated skimmers collect concentrated fat layer for recovery.

Rendering/Storage

Recovered tallow is stored and transported for rendering or sale.
