,Decanter Centrifuge for animal sludge
The Decanter Centrifuge for MBR Sludge Treatment is designed for efficient solid-liquid separation of membrane bioreactor sludge generated from advanced wastewater treatment systems.
It provides continuous sludge dewatering by separating concentrated biological solids from water, helping reduce sludge volume, improve sludge handling efficiency, and support downstream treatment such as drying, disposal, or resource recovery.

- Industrial MBR sludge treatment
- Municipal advanced wastewater treatment
- Biological sludge concentration
- Sludge reduction before drying
- Sludge disposal preparation
- Wastewater reuse systems
High Fine Solid Content
MBR sludge contains high concentrations of fine biological particles that require effective centrifugal separation.
High Bound Water Content
Biological sludge holds significant bound water, making dewatering more difficult compared with conventional sludge.
Membrane Process Stability
Excess sludge removal is important for maintaining stable MBR operation and reducing system loading.
Variable Sludge Characteristics
Sludge concentration and viscosity can change depending on wastewater conditions and biological activity.
Continuous Treatment Requirements
MBR systems require reliable equipment for continuous sludge withdrawal and automatic operation.

How the Decanter Centrifuge Works
1. MBR Sludge Feeding
Concentrated MBR sludge enters the rotating bowl through a controlled feeding system.
2. Fine Solid Sedimentation
Under centrifugal force, biological solids move toward the bowl wall and form a concentrated sludge layer.
3. Water Clarification
Separated water remains in the inner liquid zone and moves toward the clarified liquid area.
4. Sludge Conveying
The scroll continuously transports concentrated sludge toward the discharge end.
5. Continuous Dewatering
Dewatered sludge and separated water are continuously discharged for further treatment.

Why use a decanter centrifuge for MBR sludge treatment?
A decanter centrifuge provides continuous dewatering of MBR sludge, reducing sludge volume and improving downstream treatment efficiency.
Can the centrifuge handle fine biological sludge?
Yes. The decanter centrifuge is suitable for separating fine suspended solids commonly found in MBR systems.
Does MBR sludge require polymer conditioning?
In most applications, polymer conditioning improves floc formation and enhances dewatering performance.
What is the typical sludge moisture after dewatering?
The final moisture content depends on sludge characteristics and operating conditions. MBR sludge commonly achieves around 75% to 82% moisture content after centrifuge dewatering.
Can the system operate continuously?
Yes. The decanter centrifuge is designed for automatic continuous feeding, separation, and sludge discharge.
