Palm Oil Decanter Sludge Separator
,30m3/Hr Sludge Dewatering Decanter
,SS316 Decanter Centrifuge Machine
The Industrial Decanter Centrifuge for Process Water Recycling is designed for continuous solid-liquid separation in industrial water reuse and recycling systems.
It removes suspended solids, process residues, and sludge particles from circulating process water, helping improve water recovery efficiency and maintain stable production conditions.
- Industrial process water recycling
- Manufacturing wastewater reuse
- Chemical process water recovery
- Mining and mineral processing water circulation
- Paper mill process water treatment
- Food processing water recycling

Suspended Solids Accumulation
Process water may continuously accumulate suspended solids during circulation.
Sludge Generation
Process residues and contaminants may form concentrated sludge during water reuse.
Unstable Water Quality
Recycled water quality may fluctuate due to changing solids concentration and process conditions.
High Freshwater Consumption
Industrial processes require continuous water supply for production operations.
Continuous Operation Requirements
Process water recycling systems require reliable operation with minimal downtime.

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

Improved Water Recovery Efficiency
Continuous removal of suspended solids helps maintain recycled water quality and improve reuse performance.
Reduced Wastewater Discharge
Recovering process water reduces freshwater consumption and lowers wastewater treatment requirements.
Lower Sludge Handling Costs
High-efficiency separation produces concentrated solids with reduced volume for easier handling and disposal.
Stable Production Operation
Continuous solids removal helps prevent fouling, blockage, and equipment performance degradation.
Flexible Industrial Configuration
Materials, wear protection, and control systems can be customized according to different process water characteristics.

Can a decanter centrifuge be used for process water recycling?
Yes. It is designed for continuous removal of suspended solids from industrial process water and recycling systems.
What solids can be removed from process water?
It can separate suspended solids, sludge particles, mineral particles, organic residues, and other solids depending on their physical characteristics.
Can recycled water be reused directly?
The reuse quality depends on the process requirements. Additional filtration or polishing treatment may be required for sensitive applications.
Is a decanter centrifuge suitable for continuous factory operation?
Yes. It provides continuous feeding, automatic separation, and continuous solids discharge with minimal manual operation.
How does it compare with traditional filtration?
Compared with batch filtration, a decanter centrifuge offers continuous operation, automatic solids discharge, and better suitability for high-solid-load applications.
