The Three Phase Decanter Centrifuge for Industrial Emulsion Wastewater is designed for continuous separation of recovered oil, aqueous liquid, and concentrated solids.
It is suitable for wastewater containing lubricating oil, cutting oil, hydraulic oil, metal fines, rust, pigments, surfactants, and suspended sludge.
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 sludge thickening.
Industrial Emulsion Wastewater
→ Screening
→ Equalization / Optional Emulsion Breaking
→ Three Phase Decanter Centrifuge
→ Oil + Water + Solids
Recovered Oil → Recycling / Disposal
Separated Water → Further Treatment
Concentrated Solids → Filter Press / Recovery / Disposal
Conditioned emulsion wastewater enters the rotating bowl through a controlled feed pipe.
The equalization tank maintains stable flow and composition.
Centrifugal force moves metal fines, rust, pigments, and dense sludge toward the bowl wall.
The solids form a concentrated outer layer.
The lighter oil phase remains closer to the bowl center.
The heavier water phase forms a separate outer liquid layer.
The screw conveyor transports settled solids toward the conical discharge end.
Concentrated sludge is discharged continuously.
Recovered oil and separated water leave through independent outlets.
The solids discharge continuously for further dewatering, recovery, or disposal.

Separates recoverable oil, aqueous liquid, and solids in one continuous process.
Removes free oil and suspended solids before downstream treatment.
Concentrated solids require less storage and disposal capacity.
Operating parameters can be adjusted for changing oil-water-solids ratios.
PLC and VFD control support stable separation with limited manual intervention.
Please provide:
Not by centrifugal force alone in every case. Stable emulsions may require heating, pH adjustment, or emulsion-breaking chemicals first.
Possibly. Water, solids, additives, and contamination levels must be checked before reuse or reprocessing.
Usually not. Dissolved COD, surfactants, salts, and metals may require further physical, chemical, biological, or membrane treatment.
They are moved toward the bowl wall and continuously discharged. Wear protection and regular flushing help maintain stable operation.
It may alter the emulsion balance if chemical breaking is used. Reuse applications should be tested before selecting the treatment method.
Peony welcomes cooperation with metalworking plants, rolling mills, machinery manufacturers, industrial wastewater contractors, oil recyclers, and environmental engineering companies.
We support partners with wastewater testing, three-phase centrifuge selection, emulsion-breaking design, wear protection, downstream treatment integration, commissioning, spare parts, and after-sales service.
Send us your wastewater composition, flow rate, emulsion stability, recovery target, and downstream arrangement. Our engineering team will recommend a suitable three-phase decanter centrifuge solution.
