waste water treatment plant
,wastewater treatment system
This sludge dewatering system is built around a decanter centrifuge and integrated with sludge feeding, flow control, electric valves, pipeline system, turbidity monitoring, and PLC control.
It is suitable for municipal wastewater plants, industrial wastewater treatment, beer sludge, chemical sludge, and other sludge dewatering applications.
| Application | Typical Use |
|---|---|
| Municipal wastewater sludge | Sludge thickening and dewatering |
| Industrial wastewater sludge | Solid-liquid separation |
| Beer sludge | Brewery sludge dewatering |
| Chemical sludge | Sludge volume reduction |
| Food processing sludge | Organic sludge treatment |
| Paper mill sludge | Fiber sludge dewatering |
| Textile wastewater sludge | Chemical sludge separation |
| Landfill leachate sludge | Precipitated sludge dewatering |
Peony provides not only the decanter centrifuge, but also a complete sludge feeding and control system for wastewater treatment plants.
The system include:
| System Part | Function |
|---|---|
| Sludge cutting pump | Cuts and transfers sludge before feeding |
| Sludge feeding pump | Delivers sludge into the decanter centrifuge |
| Electromagnetic flowmeter | Monitors sludge feed flow |
| Electric valve | Controls automatic sludge feeding |
| Manual valve | Supports manual adjustment and maintenance |
| Pipeline system | Connects sludge, polymer, filtrate, and discharge lines |
| Turbidity meter | Monitors centrate clarity |
| Ultrasonic level meter | Detects tank or sludge level |
| PLC control cabinet | Controls automatic operation |
The typical process is:
Sludge Feeding → Flow Measurement → Polymer Dosing → Centrifugal Separation → Solid Cake Discharge → Centrate Discharge → Turbidity Monitoring → PLC Automatic Control
During operation, sludge is pumped into the rotating bowl of the decanter centrifuge. Under centrifugal force, solid particles settle on the bowl wall while clarified liquid flows out from the liquid outlet. The screw conveyor continuously pushes the dewatered sludge cake to the discharge port.
The system can be equipped with flowmeter, electric valve, turbidity meter, ultrasonic level meter, and PLC control to improve operation stability and reduce manual adjustment.
