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.
Surfactants and fine particles can keep oil dispersed in water.
Heating, emulsion breakers, coagulation, or pH adjustment may be required before separation.
Oil, water, and solids ratios may change with production and cleaning operations.
An equalization tank and adjustable phase interface help stabilize operation.
Metal fines, rust, pigments, and polishing residues may remain suspended.
Suitable conditioning improves solids capture and liquid separation.
Oil-coated metal particles may cause buildup and wear.
Flushing connections and carbide or ceramic protection can be provided.
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.
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
Screened and heated bilge waste enters the rotating bowl.
Agitation maintains a stable feed composition.
Rust, sand, sludge, and dense impurities move toward the bowl wall.
A concentrated solids layer forms.
The lighter oil phase remains closer to the bowl center.
The heavier water phase forms an outer liquid layer.
The screw conveyor transports settled solids toward the conical end.
Concentrated solids discharge continuously.
Recovered oil and separated water leave through independent outlets.
Solids discharge continuously for further treatment.

Processes bilge waste containing rust, sediment, sludge, and suspended particles.
Recovers separable oil before downstream water polishing.
Concentrates solids and reduces the volume requiring shore disposal.
Adjustable speed and phase-interface settings accommodate changing feed conditions.
Skid-mounted design supports onboard installation and integration with existing bilge systems.
Please provide:
Normally no. It should pass through approved polishing and monitoring equipment and meet applicable MARPOL and flag-state requirements.
Conditioning, heating, demulsifier dosing, or additional polishing may be required for stable emulsions.
Yes. The system can be supplied as a compact skid according to the available space, power supply, and marine requirements.
Possibly. Water, sediment, viscosity, contaminants, and fuel specifications must be tested before reuse.
Wear-protected feed zones, scroll flights, cone sections, and solids outlets can be provided.
Peony welcomes cooperation with shipowners, shipyards, marine equipment suppliers, port reception facilities, oily-waste contractors, distributors, and regional agents.
Send us your bilge-waste composition, capacity, installation space, recovery target, and downstream treatment arrangement. Our engineering team will recommend a suitable three-phase separation solution.
