How It Works
5-Step Dewatering Process – Simple & Effective
- Flow Control Tank
Precisely feeds sludge into the flocculation tank, returning excess to storage. - Flocculation Tank
Polymer is mixed with sludge to form flocs ideal for dewatering. - Thickening Zone
Initial filtration begins as water separates from sludge inside the cylinder. - Dewatering Zone
As screw pitch and ring gaps reduce, pressure increases and sludge thickens. - End Plate
Final compression removes moisture, producing up to 25% solid sludge cake
Application Areas
Municipal
Food & Dairy
Oil & Gas

FAQS
1. What is a Multi Disc Screw Press and how does it work?
A Multi Disc Screw Press is a sludge dewatering machine that separates water from sludge using a rotating screw and disc-based filtration. It gradually compresses sludge to remove moisture, producing a drier sludge cake for easier disposal.
2. What industries can benefit from using a Screw Press?
Industries such as municipal wastewater, pharmaceuticals, food & beverage, dairy, pulp & paper, chemicals, and textiles benefit from the Screw Press for efficient sludge dewatering and reduced disposal costs.
3. How much sludge dryness can Euroteck's Screw Press achieve?
4. Is the Screw Press suitable for oily or high-volatile sludge?
Yes. Euroteck’s Screw Press is designed to handle oily and volatile sludge efficiently, thanks to its slow-speed, non-clogging design and optimized compression profile.
5. How does the Screw Press compare to a centrifuge or belt press?
Compared to centrifuges and belt presses, the Screw Press consumes less energy and water, requires less maintenance, and operates with lower noise — making it a more efficient and sustainable option.
6. Does the Screw Press require a separate thickening tank?
No. The integrated design eliminates the need for a separate thickening tank, saving space and simplifying plant layout.
7. What kind of maintenance does the Screw Press require?
The Screw Press requires minimal maintenance due to its self-cleaning discs and automated flushing system. Routine checks and lubrication are typically sufficient.
8. Can the system operate continuously?
Yes. Euroteck’s Screw Press is built for continuous operation, even during self-cleaning cycles, ensuring uninterrupted performance.
9. What is the power and water consumption of the Screw Press?
The system is highly energy- and water-efficient, operating at speeds below 5 RPM, with water flushing pressure as low as 0.2 bar and power consumption under 1 kW in smaller models.
10. Is customization available for different plant capacities?
Absolutely. Euroteck offers customized Screw Press models (e.g., ESD 1.2 to ESD 50) tailored to match the specific capacity and sludge load of your treatment plant.
