The belt press filter fabric is a core component of belt filter presses. It plays a vital role in the following aspects:
1. Solid-Liquid Separation Medium: The filter cloth intercepts sludge solids particles through its pores while allowing filtrate to pass through, forming a dewatered filter cake.
2. Multi-Stage Dewatering Carrier:
Gravity Dewatering Zone: Free water naturally drains through the cloth.
Wedge Pre-press Zone: Initial compression reduces sludge fluidity.
High-Pressure Roller Zone: Further pressing lowers moisture content.
3. Continuous Operation Support: The filter cloth circulates continuously, enabling 24-hour uninterrupted processing, suitable for large-scale sludge dewatering.
4. Mechanical Pressure Transmission: It withstands high roller pressure to ensure further moisture reduction in the sludge.
Municipal Wastewater Treatment: Dewatering of biological and primary sludge for easier incineration or landfill.
Industrial Wastewater Treatment: Suitable for paper mills, textile/dyeing, electroplating, food, and pharmaceutical industries.
Mining and Chemical Industries: Reduces the volume of tailings slurry and petrochemical sludge.
Clean the filter cloth with high-pressure water after daily shutdown to prevent pore clogging.
Inspect and maintain the alignment system regularly to avoid cloth misalignment and tearing.
Avoid overloading the equipment to extend the filter belt’s service life.
Polyester filter belts offer key advantages in sludge dewatering: continuous operation, high efficiency, low energy consumption, and strong adaptability. They are a efficient solution in both municipal and industrial sludge treatment, ideal for large-scale, low-cost continuous dewatering. As a critical component, they contribute to sludge reduction and resource recovery.
Bolian specializes in the R&D and manufacturing of filter belts for the sludge dewatering industry. We offer efficient solutions including sludge dewatering filter belts, polyester spiral press filter belts, polyester spiral dryer fabrics, and plain weave square mesh belts.
