The Three Phase Decanter Centrifuge for Algae Oil Recovery continuously separates recovered algae oil, aqueous liquid, and concentrated biomass solids from conditioned algae slurry.

It is suitable for microalgae oil production, cell-disruption slurry treatment, fermentation residues, solvent-assisted extraction processes, and algae biomass dewatering before downstream purification.

• Microalgae oil recovery
• Cell-disrupted algae slurry separation
• Algae fermentation broth treatment
• Lipid-rich biomass processing
• Solvent-assisted oil extraction
• Algae protein and solids recovery
• Process-water clarification
• Biomass sludge concentration
• Pretreatment before oil polishing
• Biofuel feedstock preparation

Algae cells and cell fragments are small and slow-settling. High centrifugal force and stable feeding improve solids capture.

Stable Oil-Water Emulsions

Proteins, lipids, and cell debris may stabilize emulsions. Heating, enzymes, pH adjustment, or demulsifier dosing may be required.

Intracellular Oil

The centrifuge cannot release oil enclosed inside intact cells. Cell disruption or upstream extraction is required first.

Variable Feed Properties

Algae species, solids concentration, oil content, viscosity, and cultivation conditions can affect separation performance.

Solvent and Hygiene Requirements

Solvent-containing feeds may require gas-tight, explosion-proof construction. Food or nutraceutical applications require sanitary materials and cleaning systems.

Conditioned Algae Slurry
→ Cell Disruption
→ Feed Tank
→ Three Phase Decanter
→ Oil + Water + Biomass

Recovered Oil → Purification
Water Phase → Reuse / Treatment
Biomass → Drying / Further Processing

Peony Can Provide

• Slurry testing and selection
• Feed tank and pump
• Optional conditioning
• Adjustable phase interface
• Sanitary or solvent-resistant design
• CIP cleaning
• PLC and dual-VFD control

Continuous Algae Oil Recovery

Separates oil, water, and biomass in one continuous process.

Fine Biomass Separation

Removes algae cells, disrupted cell material, and suspended solids.

Reduced Oil Loss

Adjustable phase interface and operating speeds improve oil recovery.

Biomass By-Product Recovery

Concentrated solids can be evaluated for protein, feed, fertilizer, or biofuel applications.

Flexible Process Integration

Suitable for connection with cell disruption, extraction, purification, and drying systems.

Please provide:

• Algae species and process stage
• Oil, water, and solids content
• Particle size and cell-disruption method
• Temperature and viscosity
• Required capacity and oil recovery
• Solvent and downstream process
