Decanter Centrifuge for Manure Sludge Separation

Decanter Centrifuge for Manure Sludge Separation
Description

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.


Typical Applications
  • 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

Manure Sludge Separation Challenges

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

Manure Slurry
→ Screening
→ Mixing / Equalization Tank
→ Optional Polymer Dosing
→ Decanter Centrifuge
→ Dewatered Manure Cake + Clarified Liquid

Dewatered Solids → Composting / Organic Fertilizer Production / Disposal

Clarified Liquid → Biogas System / Further Treatment / Recycling

Peony Can Provide

  • Manure sample testing and centrifuge selection
  • Livestock waste separation evaluation
  • SS304 / SS316L corrosion-resistant contact materials
  • Adjustable bowl speed and differential speed
  • PLC automatic control system
  • Wear-resistant scroll protection
  • Flocculant dosing recommendation
  • Complete manure dewatering system integration
  • Installation guidance and after-sales service

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.

Main Advantages

Continuous Manure Dewatering

Suitable for farms requiring stable daily manure processing.

Reduced Waste Volume

Removes excess water and lowers transportation and storage costs.

Organic Solid Recovery

Recovers nutrient-rich solids for composting and fertilizer applications.

Automatic Operation

PLC control and adjustable operation parameters reduce manual labor.

Wear-Resistant Design

Carbide-protected scroll and wear-resistant components improve service life.


What Data Is Needed for Selection?

Please provide:

  • Manure source (cattle / pig / poultry / other)
  • Feed solids concentration
  • Daily processing capacity
  • Particle size distribution
  • Organic content
  • Target cake moisture
  • Liquid clarification requirement
  • Polymer usage condition
  • Downstream treatment process

FAQ

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.
