As a specialized manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been dedicated to producing high-quality filtration media since 1998. Our Polyester Single Layer Filter Belt for Sludge Dewatering Press, with a standard length of 10m and 30% air permeability, is engineered to deliver reliable performance in solid-liquid separation processes. This belt combines durability, precise filtration, and cost-efficiency, making it an ideal choice for wastewater treatment plants, mining operations, and industrial dewatering applications.
Crafted from premium polyester monofilament yarn, this single-layer filter belt offers excellent mechanical strength, dimensional stability, and resistance to chemicals and abrasion. The 30% air permeability ensures optimal drainage while retaining fine solids, resulting in a drier cake and higher throughput. With a length of 10 meters, it can be easily adapted to various press models, and custom widths are available upon request to meet specific equipment requirements.
Key Features & Technical Specifications
- High-Quality Polyester Material: Resistant to hydrolysis, acids, and alkalis, ensuring long service life even in harsh environments.
- Single Layer Construction: Provides low resistance to liquid flow, reducing energy consumption and improving dewatering efficiency.
- 30% Air Permeability: Balanced porosity for effective filtration and cake release, minimizing clogging and extending belt life.
- 10m Standard Length: Compatible with many belt press models; custom lengths and widths (e.g., 1m, 1.5m, 2m) are available.
- Pin Seam or Endless Options: Easy installation and maintenance, with optional spiral or endless joint for continuous operation.
- Working Temperature Range: Up to 150°C (optional upon request), suitable for both hot and cold sludge applications.
- High Tensile Strength: Withstands high tensioning forces without deformation, ensuring stable performance over time.

Advantages & Customer Benefits
- Improved Dewatering Efficiency: The single-layer design and 30% air permeability enhance liquid drainage, producing a drier cake (up to 20% lower moisture content compared to denser belts).
- Reduced Operating Costs: Lower energy consumption due to minimal resistance, and longer belt life (typically 12–24 months) means fewer replacements.
- Easy Maintenance: Pin seam joint allows quick installation and removal; the belt can be cleaned with standard wash water systems.
- Versatile Application: Suitable for municipal sludge, industrial sludge (food, chemical, mining), and even some pulp & paper dewatering.
- Customization Available: We offer custom lengths, widths, and joint types to match your specific press model and sludge characteristics.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of this polyester filter belt?
A: Under normal operating conditions, the belt can last 12–24 months. Lifespan depends on sludge type, tension, and cleaning frequency. Regular maintenance can extend its service life. -
Q: Can this belt be used for oily sludge or high-temperature applications?
A: Polyester is resistant to most oils and chemicals, but for high-temperature (above 100°C) or aggressive solvents, we recommend consulting our technical team. Optional heat-resistant versions are available. -
Q: How do I install the belt with a pin seam?
A: The pin seam joint allows easy installation by threading a stainless steel pin through the loops. Detailed installation instructions are provided with each order. Alternatively, an endless belt can be manufactured for seamless integration. -
Q: What is the recommended belt width for my press?
A: We can produce belts in widths from 0.5m up to 3.5m. Please provide your press model or the exact width required. We also offer custom widths to minimize waste. -
Q: How does the 30% air permeability affect filtration performance?
A: 30% air permeability is a balanced value that allows good water drainage while retaining fine solids. It is suitable for most municipal and industrial sludges. For very fine particles, a lower permeability (e.g., 20%) may be recommended; we can adjust accordingly. -
Q: Do you offer samples for testing?
A: Yes, we can provide small samples (e.g., 30cm x 30cm) for evaluation. For larger trial pieces, please contact our sales team with your requirements. -
Q: What is the minimum order quantity (MOQ)?
A: Typically, the MOQ is 1 roll (10m x standard width). For custom dimensions, the MOQ may vary. We welcome both small and large orders. -
Q: How long does shipping take?
A: Depending on the destination and shipping method, delivery usually takes 15–30 days by sea. Express shipping (e.g., DHL, FedEx) is available for urgent orders with additional cost.
