What is the Euroteck Belt Thickener?
The Euroteck Belt Thickener is a gravity-based sludge thickening system designed to reduce sludge volume before final dewatering. It prepares wastewater sludge for filter presses or screw presses by lowering water content, optimizing equipment capacity, and reducing disposal costs.
“The perfect first step in your dewatering line – compact, continuous, and automated.“
Key Features & Benefits
- Effective Moisture Reduction: Lowers sludge water content from 98–99% to 90–96%, reducing volume up to 10x.
- “Ripper” Mixing System: Continuously agitates sludge on the belt to enhance water drainage.

How It Works
Belt Thickening in 5 Steps
- Sludge Feeding: Flocculated sludge is distributed evenly onto the moving top sieve belt.
- Ripper Mixing: Ripper system agitates the sludge continuously to enhance gravity drainage.
- Gravity Drainage: Water drains naturally as the belt transports the sludge forward.
- Scraping & Discharge: Thickened sludge is removed by polymeric scrapers into a receiving bin.
- Flushing: Belt is flushed with pressurized water for self-cleaning after discharge.

FAQS
What is the primary purpose of the Euroteck Belt Thickener?
The Belt Thickener is used to reduce the volume of sludge by removing excess water through gravity-based drainage. It thickens wastewater sludge before final dewatering stages, such as screw press or belt filter press, enhancing overall efficiency and reducing equipment load.
How much moisture can be removed using the Belt Thickener?
The system can reduce sludge moisture from 98–99% to 90–96%, which translates to a 3–10x reduction in sludge volume. This significant reduction helps minimize transport and disposal costs downstream.
Can the Belt Thickener operate continuously?
Yes. The unit is designed for continuous, automatic operation. It seamlessly integrates with other dewatering equipment for uninterrupted sludge processing, making it ideal for plants that run 24/7.
Is this system suitable for all types of sludge?
The Euroteck Belt Thickener is optimized for municipal wastewater sludge and many types of industrial sludge, including from food processing, pulp & paper, and chemical industries. It works best with sludge within the pH range of 6.0–9.0.
What construction materials are used for durability?
The main body is made of AISI 304 stainless steel, offering excellent corrosion resistance. High-load shafts are made of carbon structural steel and are polymer-coated for long-lasting performance in aggressive environments.
What makes the “ripper” system special?
The ripper system continuously agitates the sludge as it moves on the sieve belt. This enhances water drainage by breaking surface tension, ensuring more effective gravity separation than static systems.
Is the system fully automated?
Absolutely. The Belt Thickener includes:
- Belt tracking and tension sensors
- Speed control
- Air pressure drop protection
- Emergency alert indicators
These features enable automated monitoring and control, and data can be integrated with higher-level SCADA systems on request.
How is the belt cleaned during operation?
After sludge is scraped off, the belt enters a flushing zone where pressurized water cleans it thoroughly. This self-cleaning mechanism ensures continuous performance and prolongs belt life.
Can the thickener be mounted with other equipment?
Yes. In the “Comby” version, the thickener can be mounted directly onto the frame of a belt filter press, where thickened sludge is automatically fed for final dewatering — saving space and simplifying operations.
What maintenance is required, and how easy is it?
Maintenance is minimal. Thanks to visual access design, wear-out elements like belts and scrapers are easy to inspect and replace using standard tools. The automation system also provides alerts for any abnormal operation, reducing manual checks.
