Frequently Asked Questions
-
Q: What is the typical lifespan of this filter cloth under normal operating conditions?
A: The lifespan depends on the application, slurry characteristics, and operating pressure. In typical municipal wastewater sludge dewatering, our cloths can last 6–12 months. For mining applications with abrasive materials, a lifespan of 3–6 months is common. We recommend regular maintenance and proper cleaning to extend service life. -
Q: Can this filter cloth be used with polyacrylamide (PAM) flocculants?
A: Yes, the 100% polyester material is compatible with most common flocculants used in belt filter presses. However, we advise testing under actual process conditions to ensure optimal cake release and cloth performance. -
Q: Do you provide custom sizes for specific belt filter press models?
A: Absolutely. We can cut the cloth to your exact width and length, and add edge reinforcements (heat-cut, folded, or welded) to match your press's clamping system. Please provide your current cloth dimensions or a drawing for a customized quote. -
Q: How do I clean the filter cloth to maintain its permeability?
A: We recommend using high-pressure water jets (up to 100 bar) or chemical cleaning agents that are compatible with polyester. For organic fouling, a mild alkaline wash is effective. Avoid using strong oxidizing agents like bleach, as they may degrade the polyester fibers. -
Q: Is this filter cloth suitable for high-temperature applications above 100°C?
A: Standard polyester cloth can withstand continuous temperatures up to 150°C. For applications exceeding this threshold, we offer a high-temperature variant with modified fibers. Please contact us with your specific temperature requirements. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 10 rolls per specification. For trial orders or custom prototypes, we can accommodate smaller quantities. Lead time for standard orders is 15–20 working days after confirmation. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples of up to 30 cm x 30 cm for evaluation. You only need to pay for shipping. Samples are available in standard weaves and colors, and we can also provide sample swatches of custom specifications upon request. -
Q: How do you ensure the quality consistency of each batch?
A: We follow a strict quality management system. Each batch of yarn is tested for tensile strength and elongation. During weaving, we monitor air permeability and thickness at multiple points. A final inspection report is provided with every shipment, including test results for the key parameters.
