RF-B-FD-A7-68
Filter belt for sludge dewatering in wastewater treatment plants
RF-B-FD-A7-68 Filter Belt: High-Performance Dewatering Belt for Wastewater Treatment Plants
Robust Filtration Belt for Belt and Drum Thickeners
The RF-B-FD-A7-68 filter belt is engineered for efficient sludge dewatering in municipal and industrial wastewater treatment plants. Designed for use on belt thickeners and drum thickeners, this belt combines high flow rates with strong mechanical stability to deliver reliable thickening and filtration performance. Its Twill structure and optimized aperture design make it ideal for continuous operation in demanding sludge treatment environments.
Key Features and Benefits of the RF-B-FD-A7-68 Filter Belt
Twill Weave for Controlled Filtration and Strength:
The Twill weave provides improved particle retention and a stable textile structure that offers superior resistance to deformation, mechanical stress and bending.Optimized Aperture Structure for Efficient Dewatering:
The asymmetric aperture size of 1100 × 590 µm ensures a balance between effective drainage and reliable solids retention — ideal for primary and biological sludge on thickening equipment.High Flow Rate for Faster Thickening Cycles:
With an air permeability of 5,509 l/m²/s, the RF-B-FD-A7-68 supports rapid water removal, increasing throughput and improving the efficiency of downstream dewatering systems such as belt filter presses.High Mechanical Stability and Crease Resistance:
Designed for continuous operation, this belt maintains its shape and performance even under high loading, repeated flexing and constant moisture exposure — helping prevent premature wear and belt deformation.Durable PET Construction:
Made entirely from Polyester (PET) warp and weft, the belt provides excellent service life, chemical resistance and dimensional stability in challenging wastewater environments.Stock Availability up to 3.2 m Width:
The RF-B-FD-A7-68 is often available from stock in widths up to 3.2 meters, ensuring fast replacement when plant uptime is critical.Flexible Seam Options:
This model can be supplied with:
• Stainless steel Clipper seam
• Pin seam
• Woven endless seam
ensuring full compatibility with a wide range of thickening systems.
Why Choose the RF-B-FD-A7-68 for Your Sludge Dewatering Process?
The RF-B-FD-A7-68 is the ideal filter belt for wastewater treatment facilities that require a durable, high-flow and crease-resistant textile for efficient sludge thickening. Its Twill weave, optimized aperture size and consistent mechanical stability ensure reliable performance across both belt and drum thickening systems.
