Filter bag drainage system: Maximum performance thanks to polypropylene fleece
The "Winkler way" focuses on quality and durability. Our disposable filter bags for sludge dewatering are made from high-quality polypropylene fleece (PP). This material is hydrophilized, ensuring an optimal flow rate while maintaining excellent particle retention.
Our systems are used in:
- Wastewater treatment & sewage treatment plants: For the dewatering of primary and secondary sludge.
- Construction site drainage: Separation of drilling mud or sediments.
- Recycling & Industry: Recovery of solids from process wastewater.
Specialized solutions for paint sludge and splitting plants
Not all sludge is the same. Particularly when disposing of industrial waste such as paint sludge or paint residues, high levels of contamination are encountered.
Requirements were placed on tear resistance and filter fineness.
Filter bags for splitting plants & paint sludge fleece
For use in chemical-physical cracking plants, we offer specialized filter bags . Our paint sludge fleece and the "Color Drain" series are optimized to reliably trap sticky or fine particles within the bag, while allowing the treated water to drain away unimpeded. This protects your plant and significantly reduces disposal costs by minimizing sludge volume.
Perfect fit for drainage boxes from Classic
up to XXL
For the filter bag drainage to function smoothly, the size must be correct. We carry standardized sizes for common drainage boxes :
- Classic & Small: For mobile units or low volumes (e.g. 0.125 m³).
- Medium & XL: The all-rounders for standard industrial applications (0.5 m³ to 0.8 m³).
- XXL & GE Vernova: Special sizes (1.25 m³) for maximum capacity and specific plant types such as GE Vernova.
Dewatering sludge and reducing costs
With the right dewatering bag, you can drastically minimize the moisture content of your solids. This results in easier handling and significant savings on landfill or incineration fees. Trust Winkler Filtertechnik for professional solutions for dewatering boxes and industrial filtration.
FAQ – Frequently Asked Questions about Filter Bags & Sludge Dewatering
Do you have questions about efficient sludge dewatering or are you looking for the right filter bag for your dewatering box ? In our FAQ section, the experts at Winkler Filtertechnik have compiled the most important information for you. Learn all about the material advantages of polypropylene fleece , the proper disposal of paint sludge , and how to optimize residual dewatering in cracking plants to sustainably reduce your process costs.
The choice of filter bag depends primarily on the volume of your dewatering box and the type of sludge. For standard applications in workshops or small splitting plants, the 0.125 m³ size is often sufficient. In industrial settings, the 0.5 m³, XL (0.8 m³) , or XXL (1.25 m³) versions are most commonly used. Ensure that the bag is securely seated in the housing to guarantee optimal residual dewatering .
Our sludge filter bags are designed as high-quality, disposable filter bags . This is for hygienic and functional reasons: The incorporation of the finest particles into the polypropylene fleece causes the fabric to clog over time, guaranteeing the filter's filtration efficiency. Washing would destroy the pore structure and drastically reduce the filtration performance.
Polypropylene fleece is highly chemically resistant and extremely tear-resistant. Our filter bags are also hydrophilized. This means they allow water to pass through quickly while efficiently retaining solids. This is particularly important in sludge dewatering to accelerate the process and optimize plant uptime.
In paint sludge dewatering, the filter bag also serves as a transport medium. After complete dewatering in the dewatering box, the bag, along with its solid contents (which now have a significantly smaller volume), can be disposed of in accordance with local waste regulations. This effective separation results in considerable savings on disposal costs for liquid hazardous waste.
Yes, our filter bag dewatering system in particular is frequently used in smaller wastewater treatment plants or industrial facilities for sludge conditioning. It supports wastewater treatment by pre-concentrating the sludge, thus relieving the burden on subsequent processes.
