Screw Press Introduction
Volute Sludge Dewatering Machine is an advanced technology dehydrator (TPDL) belonging to the screw press category. It is designed to replace traditional machines like belt presses and frame presses. Its clog-free design significantly reduces the need for sedimentation and thickening tanks, thereby saving construction costs for sewage plants.
Structure & Operation Principle
Wastewater is pushed into the dewatering machine where sludge moves toward the outlet under pressure from helical axis blades. As the gap between the blades narrows, the sludge undergoes heavy pressure, initiating the dewatering process. Water is expelled through the spaces between the fixed and moving plates.
Key Advantages
- Low Operation Cost: Below 40% of belt press and 20% of centrifuge.
- Power-saving: Consumes less than 5% of the energy required by a centrifuge.
- Water-saving: Less than 0.1% water usage compared to belt filter presses.
- Chemical Efficiency: Saves approximately 60% on drug/polymer usage.
- Compact Design: Saves over 60% of investment costs for the dehydration room.
- Non-clogging: Perfectly processes fats, oils, and fiber-heavy sludge.

Frequently Asked Questions (FAQ)
Q1: What makes the Volute Sludge Dewatering Machine "clog-free"?
The machine uses a series of fixed and moving rings that self-clean during the rotation of the screw, preventing clogging even when handling oily or fibrous sludge.
Q2: How does this machine compare to traditional belt filter presses?
The screw press offers much lower operation costs (below 40% of a belt press) and uses significantly less water (less than 0.1% compared to belt presses) while occupying less space.
Q3: Can this equipment handle chemical factory wastewater?
Yes, it is specifically designed for industrial applications including chemical factories, tanneries, and textile plants where efficient sludge thickening and dewatering are required.
Q4: Is the machine energy efficient?
Absolutely. The power consumption is less than 5% of a traditional centrifuge, making it one of the most eco-friendly dewatering solutions available.
Q5: What kind of shipping protection is provided?
We use reinforced wooden pallets or standard export wooden boxes to ensure the equipment is protected against moisture and physical damage during international transit.
Q6: What data do I need to provide for a model recommendation?
To select the best model, please provide the sludge flow rate (M3/H), solid content percentage, sludge character, and your desired target moisture content for the sludge cake.
