Three Phase Decanter Centrifuge for Marine Bilge Oil Separation
Description

The Three Phase Decanter Centrifuge for Marine Bilge Oil Separation continuously separates recoverable oil, water, and concentrated solids from high-solids bilge waste.

It is suitable for bilge holding-tank sludge, engine-room oily wastewater, waste-oil residues, and marine oily-waste pretreatment. 


Typical Applications
  • Bilge holding-tank sludge
  • Engine-room oily wastewater
  • Waste-oil tank residues
  • Fuel and lubricant leakage mixtures
  • Marine separator sludge
  • Shipyard oily-waste treatment
  • Port reception-facility waste
  • Pretreatment before oily-water polishing

Marine Bilge Oil Challenges

Stable Oil-Water Emulsions

Surfactants and fine particles can keep oil dispersed in water.

Heating, emulsion breakers, coagulation, or pH adjustment may be required before separation.

Variable Oil Content

Oil, water, and solids ratios may change with production and cleaning operations.

An equalization tank and adjustable phase interface help stabilize operation.

Fine Suspended Solids

Metal fines, rust, pigments, and polishing residues may remain suspended.

Suitable conditioning improves solids capture and liquid separation.

Sticky and Abrasive Sludge

Oil-coated metal particles may cause buildup and wear.

Flushing connections and carbide or ceramic protection can be provided.

Dissolved Pollutants

The centrifuge removes free oil and suspended solids but does not fully remove dissolved COD, salts, surfactants, or dissolved metals.

Further treatment may still be required.


Marine Bilge Oil Separation Solution

Peony provides three-phase separation solutions for oil recovery, water clarification, and bilge-sludge thickening.

Marine Bilge Waste
→ Screening
→ Heated Equalization / Optional Emulsion Breaking
→ Three Phase Decanter Centrifuge
→ Oil + Water + Solids

Recovered Oil → Storage / Reprocessing
Separated Water → Oily-Water Polishing System
Concentrated Solids → Dewatering / Shore Disposal

Peony Can Provide

  • Bilge-waste testing and centrifuge selection
  • Heated equalization tank and controlled feed pump
  • Optional demulsifier dosing and feed heating
  • Adjustable bowl speed, differential speed, and phase interface
  • Wear protection and automatic flushing
  • PLC and VFD control
  • Compact marine skid and three-phase collection system

How the Decanter Centrifuge Works

1. Conditioned Bilge Feeding

Screened and heated bilge waste enters the rotating bowl.

Agitation maintains a stable feed composition.

2. Solids Sedimentation

Rust, sand, sludge, and dense impurities move toward the bowl wall.

A concentrated solids layer forms.

3. Oil-Water Separation

The lighter oil phase remains closer to the bowl center.

The heavier water phase forms an outer liquid layer.

4. Continuous Solids Conveying

The screw conveyor transports settled solids toward the conical end.

Concentrated solids discharge continuously.

5. Three-Phase Discharge

Recovered oil and separated water leave through independent outlets.

Solids discharge continuously for further treatment.

Main Advantages

High-Solids Bilge Handling

Processes bilge waste containing rust, sediment, sludge, and suspended particles.

Recoverable Oil Separation

Recovers separable oil before downstream water polishing.

Reduced Waste Volume

Concentrates solids and reduces the volume requiring shore disposal.

Stable Continuous Operation

Adjustable speed and phase-interface settings accommodate changing feed conditions.

Compact Marine Configuration

Skid-mounted design supports onboard installation and integration with existing bilge systems.


What Data Is Needed for Selection?

Please provide:

  • Oil, water, and solids content
  • Flow rate and temperature
  • Emulsion stability
  • Particle size and solids type
  • Installation space
  • Downstream polishing system

FAQ

Can the separated water be discharged directly overboard?

Normally no. It should pass through approved polishing and monitoring equipment and meet applicable MARPOL and flag-state requirements.

Can it handle detergent-stabilized bilge emulsions?

Conditioning, heating, demulsifier dosing, or additional polishing may be required for stable emulsions.

Is it suitable for onboard installation?

Yes. The system can be supplied as a compact skid according to the available space, power supply, and marine requirements.

Can the recovered oil be reused as fuel?

Possibly. Water, sediment, viscosity, contaminants, and fuel specifications must be tested before reuse.

How are rust and abrasive solids handled?

Wear-protected feed zones, scroll flights, cone sections, and solids outlets can be provided.
