Frequently Asked Questions
-
Q: What is the recommended washing method for this filter cloth?
A: Rinse with clean water or a mild detergent solution. Avoid high-pressure water jets that may damage the weave. The cloth can be cleaned in place on the belt filter using a spray bar system. For stubborn residues, a 2% caustic soda solution (pH ≤ 12) can be used, but avoid prolonged exposure to strong acids or alkalis beyond the recommended pH range. -
Q: Can this cloth be used for fine particle filtration (e.g., less than 10 microns)?
A: Yes, the 500g/m² PET filter cloth can achieve retention of particles down to 5–10 microns depending on the weave pattern. For finer filtration, we recommend a twill or satin weave with higher thread density. Please contact our technical team with your specific particle size distribution for a tailored recommendation. -
Q: How long does the cloth typically last under normal operating conditions?
A: Service life varies based on application, chemical exposure, temperature, and mechanical wear. In typical municipal sludge dewatering, the cloth can last 6–12 months. In less abrasive applications such as chemical filtration, it may last over 2 years. Our 1-year warranty covers manufacturing defects, but proper maintenance can extend lifespan significantly. -
Q: Is the free sample provided with sewn edges or cut edges?
A: The free sample is typically provided with cut edges, but we can also supply a sample with sewn edges upon request. The sample size is approximately 100mm × 100mm, which is sufficient for permeability testing and visual inspection. For trial runs on a small belt filter, we can provide larger samples (e.g., 0.5m × 1m) at a nominal cost. -
Q: What is the lead time for bulk orders?
A: For standard widths and lengths, the lead time is 7–15 days after order confirmation. Customized orders may require 15–25 days. We maintain a stock of commonly used specifications to expedite delivery. Rush orders can be accommodated for an additional fee. -
Q: Do you offer sewn-on belts or endless belts for belt filter presses?
A: Yes, we can provide finished belts with sewn joints, clipper lacing, or endless weaving. The 500g/m² PET cloth is suitable for making endless belts with a strong joint. Please specify your belt filter make and model, and we will provide the appropriate configuration. -
Q: How does the cloth perform in high-temperature applications (above 100°C)?
A: Polyester has a maximum continuous operating temperature of 150°C. For temperatures above 150°C, we recommend a different material such as aramid or PEEK. Our PET cloth can withstand brief spikes up to 170°C, but prolonged exposure beyond 150°C will reduce service life. Please consult with our engineers for high-temperature applications. -
Q: Can I get a certificate of analysis (COA) for each batch?
A: Yes, we provide a COA upon request, including weight, thickness, tensile strength, and air permeability data. Our quality control system tracks each production batch, ensuring traceability and consistency.
