Sludge Inlet
The feed connection into the thickening zone
Feeding the Press
The sludge inlet delivers conditioned, flocculated sludge into the first (thickening) zone of the screw press. A steady, controlled feed rate is essential for stable dewatering performance and consistent cake quality.
Feed is usually supplied by a progressive cavity pump whose speed is coordinated with the screw and polymer dosing. Over-feeding floods the machine; under-feeding wastes capacity.
Key Points
- Steady feed rate for stable operation
- Fed by a progressive cavity or similar low-shear pump
- Coordinated with polymer dosing and screw speed
