Alloy Tiles Decanter Centrifuge
,3 Phase Liquid-Liquid-Solid Centrifuge
,VFD control box Decanter Centrifuge
The Industrial Decanter Centrifuge for Manufacturing Wastewater Solids continuously separates suspended solids from industrial wastewater.
It is suitable for metal processing, chemical production, coating, machining, mineral processing, and general manufacturing wastewater.
- CNC machining wastewater with metal fines and grinding swarf
- Automotive parts washing wastewater with rust and suspended solids
- Electroplating sludge containing metal hydroxides
- Paint, coating, and surface-treatment wastewater
- Ceramic, glass, and polishing slurry dewatering
- Chemical manufacturing wastewater with precipitated solids
- Bearing, casting, and foundry wastewater sludge
- Pretreatment before filter press, membrane, or water-reuse systems
Fine Suspended Solids
Fine particles may settle slowly and reduce water clarity.
Variable Feed Conditions
Solids concentration, particle size, and flow rate may change during production.
Abrasive Materials
Metal, mineral, and ceramic particles can cause equipment wear.
Sticky Sludge
Oil, polymers, paint residues, and chemicals may affect solids conveying.
Water-Reuse Requirements
The separated liquid may require polishing before reuse or discharge.
Manufacturing Wastewater Solids Solution
Manufacturing Wastewater
→ Screening
→ Equalization / Optional Flocculation
→ Decanter Centrifuge
→ Clarified Water + Dewatered Solids
Clarified Water → Further Treatment / Reuse
Dewatered Solids → Recovery / Filter Press / Disposal
Peony Can Provide
- Wastewater testing and centrifuge selection
- Feed tank and controlled pump
- Optional flocculant dosing
- Adjustable bowl and differential speed
- Wear protection and automatic flushing
- PLC and VFD control
How the Decanter Centrifuge Works
1. Wastewater Feeding
Conditioned wastewater enters the rotating bowl.
2. Solids Sedimentation
Dense particles move toward the bowl wall.
3. Liquid Clarification
Separated water remains near the bowl center.
4. Solids Conveying
The screw conveyor moves solids toward the conical end.
5. Continuous Discharge
Clarified water and dewatered solids discharge separately.

Main Advantages
High-Solids Wastewater Handling
Processes manufacturing wastewater containing metal fines, grinding sludge, mineral particles, paint residues, and precipitated solids.
Continuous Sludge Dewatering
Continuously removes suspended solids without the batch cycles required by filter presses.
Reduced Sludge Volume
Concentrates industrial solids to reduce storage, transport, and disposal costs.
Improved Water Clarification
Removes suspended particles before downstream filtration, biological treatment, membrane systems, or water reuse.
Wear-Resistant Industrial Design
Optional carbide or ceramic protection improves service life when handling abrasive metal, mineral, ceramic, or glass particles.
Please provide:
- Solids concentration
- Particle size and density
- Flow rate and temperature
- Oil or chemical content
- Required cake dryness
- Water-quality target
Can it handle fine manufacturing solids?
Yes. Very fine particles may require flocculant conditioning.
Can it treat oily wastewater?
Yes, but high oil content or stable emulsions may require pretreatment.
What affects solids dryness?
Feed properties, bowl speed, differential speed, pond depth, and throughput.
Is wear protection necessary?
It is recommended for metal fines, minerals, ceramics, and abrasive sludge.
Can the clarified water be reused directly?
Possibly. The water should first meet the downstream process-quality requirements.
Peony welcomes cooperation with manufacturing plants, metalworking companies, automotive-parts producers, coating and chemical factories, wastewater-treatment contractors, equipment distributors, and regional agents.
We support partners with wastewater testing, decanter centrifuge selection, flocculant evaluation, wear-resistant configuration, process integration, commissioning, spare parts, and after-sales service.
Send us your wastewater composition, solids concentration, particle size, flow rate, target cake dryness, and clarified-water requirement. Our engineering team will recommend a suitable manufacturing wastewater solids separation solution.
