Choosing the right sludge dewatering equipment is crucial for operational efficiency and cost savings. Compare volute screw press and centrifuge technologies.

Volute Screw Press Technology

The volute screw press uses a unique rotating screw within a cylindrical screen:

• Continuous operation
• Low energy consumption (0.3-0.5 kW/m3)
• Minimal maintenance requirements
• No clogging or blocking
• Dry solids content: 18-40%

Centrifuge Technology

Centrifugal separation uses high-speed rotation with higher energy consumption and maintenance needs.

Cost Comparison

Volute presses offer lower initial investment, lower operating costs, easier maintenance, and longer lifespan compared to centrifuges.
