Sludge Vertical Decanter Centrifuge
,High Rotational Speed Decanter Centrifuge
,High Rotational Speed Sludge Decanter
The Industrial Decanter Centrifuge for Filter Press Feed Thickening is designed to increase slurry solids concentration before filter press dewatering.
By removing excess liquid and producing a more concentrated sludge feed, the decanter centrifuge helps improve filter press efficiency, reduce filtration cycle time, and lower sludge handling costs.
- Filter press feed concentration
- Industrial wastewater sludge treatment
- Mining tailings thickening
- Mineral concentrate slurry preparation
- Chemical process sludge dewatering
- Municipal wastewater sludge treatment
- Metal processing sludge
- Battery material slurry recovery
- Ceramic and mineral slurry concentration
- Pretreatment before plate and frame filter press
Suspended Solids Accumulation
Recycled water may continuously accumulate suspended solids during circulation.
Sludge Generation
Process residues and contaminants may form concentrated sludge in circulating water systems.
Scaling and Fouling Risk
Suspended solids and impurities may cause scaling, blockage, and fouling in pipelines and equipment.
Freshwater Consumption Reduction
Industrial plants require higher water reuse rates to reduce freshwater intake and wastewater discharge.
Continuous Operation Requirements
Batch separation methods may require frequent cleaning, replacement, and manual operation.

How the Decanter Centrifuge Works
1. Wastewater Feeding
Circulating water containing suspended solids enters the rotating bowl through a controlled feed system.
2. Solid Sedimentation
Under centrifugal force, solid particles move toward the bowl wall and form a concentrated sludge layer.
3. Liquid Clarification
Separated water remains in the inner liquid zone and moves toward the liquid discharge outlet.
4. Continuous Sludge Conveying
The scroll transports settled solids toward the conical discharge end.
5. Separate Discharge
Clarified recycled water and concentrated sludge are discharged continuously through separate outlets.

Main Advantages
Improved Water Recycling Efficiency
Continuous removal of suspended solids helps maintain recycled water quality and improves reuse performance.
Reduced Sludge Disposal Volume
High-efficiency dewatering produces concentrated sludge with lower moisture content, reducing transportation and disposal costs.
Stable Closed-Loop Operation
Automatic solid removal helps prevent fouling, scaling, and equipment performance decline.
Continuous Automatic Separation
The decanter centrifuge operates continuously without filter replacement or frequent manual cleaning.
Flexible Industrial Configuration
Materials, wear protection, and control systems can be customized according to water quality and process conditions.
Please provide:
- Water source and application
- Suspended solids concentration
- Sludge characteristics
- Flow rate (m³/h)
- Particle size distribution
- Required recycled water quality
- Operating temperature
- pH and chemical composition
- Corrosion requirements
- Required sludge moisture content
Can a decanter centrifuge be used for water recycling systems?
Yes. It is widely used for continuous removal of suspended solids from industrial circulating water and wastewater reuse systems.
Can it replace filters in closed-loop water systems?
It depends on the process requirements. A decanter centrifuge is especially suitable for high-solid-load applications requiring continuous sludge removal.
What types of solids can it remove?
It can separate sludge, mineral particles, process residues, biological solids, and other suspended materials depending on particle characteristics.
Can the separated water be reused directly?
The clarified water quality depends on the feed characteristics and process requirements. Additional polishing treatment may be required for sensitive applications.
Is the system suitable for continuous factory operation?
Yes. The decanter centrifuge is designed for continuous feeding, automatic separation, and continuous solids discharge.
