Belt filter press: Highly efficient sludge dewatering

In wet processing, responsible process water treatment is more than just an ecological obligation—it is a decisive lever for your economic efficiency. Our belt filter presses have been specially designed to efficiently dewater mineral sludge in a continuous process.

Our belt filter presses make sludge treatment highly efficient and resource-saving:

Maximum dewatering performance: The systems operate 24/7 with capacities ranging from 7 to 21 t/h. Even with clay-rich sludge, they produce stable, manipulable filter cakes.
Versatile use: Thanks to their compact design, the belt filter presses are ideal for dewatering sludge from primary raw material extraction as well as from construction waste and soil excavation processing.
Sustainability with a system: Sludge dewatering is the perfect complement to process water treatment and greatly increases the efficiency of your treatment processes.
Everything from a single source: Binder+Co sees itself as a plant planner and builder without additional external interfaces. We work with you to define the scope of the project, design your process, and deliver tailor-made machines along the entire process chain: from crushing and screening technology to sand processing and process water and sludge treatment.

Belt filter press from COMEC-Binder: Our advantages

Our belt filter presses are an efficient solution for continuously dewatering sludge, closing water cycles, and sustainably reducing operating costs. All advantages at a glance:

MAXIMUM THROUGHPUT

Continuous 24/7 dewatering process with capacities from 7 to 21 t/h without cycle-related downtimes.

SPECIALIST FOR HIGH CLAY CONTENT

Superior processing of clay-rich sludge (0-90 μm) to produce filter cakes with a firm consistency.

LOW SPACE REQUIREMENTS

Our belt filter presses have a compact design that allows them to be installed in very limited spaces.

INNOVATIVE TECHNOLOGY

Multi-stage system with innovative reversal effect and continuously increasing press pressure for efficient sludge dewatering.

SUSTAINABILITY & RECOVERY

The effective recovery of process water conserves resources and efficiently closes water cycles.

LOW-MAINTENANCE OPERATION

Maximum plant availability thanks to sensor-supported belt centering, pneumatic tensioning, and integrated high-pressure cleaning.

How the belt filter press works

Our belt filter presses continuously separate solids from water. The entire process is fully automatic and designed for high throughput:

1. Mixing and preparation

First, the thickened sludge (from process water treatment) enters a reactor upstream of the belt filter press. There it is mixed with a flocculant. This step ensures that the fine solids in the sludge combine to form larger flocs so that clean water can be pressed out in the next step.

2. Pre-dewatering and turning of the material

The sludge is distributed evenly on the filter belt. Most of the water already flows off at this stage. The sludge cake is then turned.

3. Dewatering by increasing pressure

The sludge is then pressed between two belts. As the rollers become smaller and smaller in the direction of travel, the pressure increases steadily. This results in as much water as possible being pressed out and a solid cake being formed.

4. Material discharge and belt cleaning

At the end, scraper blades remove the dewatered sludge from the belts. To maintain consistent filter performance, the belts are cleaned with high-pressure nozzles. Sensors and compressed air cylinders automatically ensure that the belts run taut and centered.

Versatile applications for our belt filter presses

Our belt filter presses are mainly used in the primary raw materials industry and in the processing of secondary raw materials such as excavated soil and construction waste.

Raw material extraction: Processing of mineral sludge, gravel, and industrial minerals.
Recycling industry: Recovery of recyclable materials and processing of construction waste, building residues, and excavated soil.

Everything from a single source: The system solution for your plant

Binder+Co supplies the entire process chain from crushing and screening technology to sand processing and process water and sludge treatment from a single source. Since all machines are perfectly coordinated, you avoid interface losses and reduce overall costs compared to individual purchases from different suppliers.

Differences: Belt filter press and chamber filter press

The choice of the right dewatering system depends on the sludge composition and the structural requirements.

Belt filter press

The belt filter press is the solution for sludge with a high clay content. It dewaters sludge continuously and produces filter cakes that can be handled. It has a compact design and can be used in a semi-mobile configuration. Depending on the size, its capacity ranges between 7 and 21 t/h.

Advantages of the belt filter press:

Compact design
Ideal for sludge with a high clay content

Chamber filter presses

The chamber filter press is the first choice for maximum dewatering and delivers stable filter cakes with minimal residual moisture. It is operated in conjunction with a sludge storage tank to ensure a smooth process. The capacity of a single press is up to 33 t/h.

Advantages of chamber filter presses:

Minimal residual moisture
High throughput

OUR CHAMBER FILTER PRESSES

Frequently asked questions about our belt filter presses

Yes. If necessary, the required thick sludge is produced from a sand/gravel mixture in our in-house technical center. This thick sludge is then fed into the chamber filter press to determine precise dewatering results for your material.

Reference plants can be visited by appointment. We would be happy to show you solutions that work with similar material compositions.

The cleaning interval depends heavily on the sludge composition. The belt filter press continuously cleans the belts with high-pressure nozzles. For chamber filter presses, we offer an automated plate washing system.
