Boost Dewatering Efficiency with Screw Press and Integrated Auxiliary Equipment

JX Filtration May 28, 2025 Screw Press

The screw press sludge dewatering machine has become a popular choice in municipal and industrial wastewater treatment due to its energy efficiency, stable operation, and minimal maintenance requirements. However, to achieve optimal performance, relying solely on the main dewatering unit is not enough. Properly configured auxiliary systems play a crucial role in enhancing dewatering efficiency, ensuring continuous operation, and extending equipment lifespan.

1. Sludge Feed Pump
A reliable sludge feed pump—typically a progressive cavity pump or diaphragm pump—is essential for transporting sludge from the holding tank to the screw press. Choosing the right pump based on sludge viscosity and concentration ensures a stable and continuous flow, which is critical for maintaining consistent treatment performance.

2. Polymer Dosing System
Efficient flocculation is key to maximizing dewatering performance. An automatic polymer dosing system—including a solution tank, dissolving unit, and metering pump—ensures accurate and consistent flocculant preparation and dosing. This leads to the formation of robust flocs, significantly improving solid-liquid separation and reducing sludge cake moisture content.

3. Mixing and Flocculation Tank
To promote thorough mixing of sludge and polymer, a mixing or flocculation tank is typically installed before the screw press. The system ensures the right reaction time and gentle agitation to avoid breaking the floc structure, thus enhancing the overall separation efficiency.

4. Electrical Control Panel and PLC System
An integrated PLC-based control panel automates the operation of the entire system, including sludge feeding, polymer dosing, and screw press operation. Features like one-touch startup, real-time monitoring, and fault alarms reduce manual workload and improve reliability.

5. Sludge Cake Conveying System
To facilitate post-treatment handling, a screw conveyor or belt conveyor can be connected to the sludge cake discharge port, transporting the dewatered solids to a designated storage or disposal area. This addition ensures a cleaner and more streamlined operation.

By combining a screw press with a complete set of auxiliary equipment, users can significantly improve dewatering efficiency, lower operating costs, and reduce manual intervention.
