Decanter Centrifuge for Manure Sludge Separation
The Decanter Centrifuge for Manure Sludge Separation is designed for continuous solid-liquid separation of livestock manure slurry and organic waste streams.
It is suitable for cattle manure, pig manure, poultry manure, biogas digestate, and agricultural wastewater treatment applications.
The centrifuge separates suspended solids from liquid manure through high-speed centrifugal force, producing dewatered manure cake and clarified liquid. It helps reduce manure volume, improve transportation efficiency, and recover organic solids for composting or fertilizer production.
- Cattle manure dewatering
- Pig manure sludge separation
- Poultry manure treatment
- Livestock farm wastewater treatment
- Biogas digestate separation
- Anaerobic digestion residue dewatering
- Organic fertilizer raw material recovery
- Agricultural wastewater solid-liquid separation
High Water Content
Fresh manure slurry contains a large amount of water, resulting in high transportation and storage costs.
Sticky Organic Solids
Manure contains fibers, proteins, and organic particles that are difficult to separate by traditional settling methods.
Variable Solids Concentration
Feed concentration changes according to animal type, feeding method, dilution water, and farm operation.
Fine Suspended Particles
Small organic particles can remain suspended for long periods and reduce liquid clarification efficiency.
Odor and Environmental Control
Improper manure handling can create odor problems and increase environmental management pressure.
Continuous Treatment Requirements
Large-scale farms require stable and automatic equipment for daily manure processing.
Manure Sludge Separation Process

How the Decanter Centrifuge Works
1. Manure Feeding
Manure slurry enters the rotating bowl continuously.
2. Solid Sedimentation
High centrifugal force separates organic solids from the liquid phase.
3. Liquid Clarification
Separated liquid moves toward the center and exits through the liquid outlet.
4. Solid Conveying
The internal screw conveyor transports concentrated solids toward the discharge end.
5. Continuous Discharge
Dewatered manure cake is discharged continuously for further processing.

What manure types can this centrifuge handle?
It can process cattle manure, pig manure, poultry manure, biogas digestate, and other livestock sludge applications.
Does it reduce manure transportation costs?
Yes. By removing excess water, the centrifuge reduces sludge volume and improves handling efficiency.
Is polymer required for manure separation?
Not always. Polymer may improve separation performance when fine particles or low settling solids are present.
Can the separated solids be used as fertilizer?
Yes. Dewatered manure solids can be further processed through composting or fertilizer production according to local requirements.
Is the centrifuge suitable for continuous operation?
Yes. The decanter centrifuge provides continuous feeding, separation, and discharge for large-scale manure treatment.
