Frequently Asked Questions
-
Q: Can this cloth be used for dewatering of municipal sludge?
A: Yes, our polyester filter cloth works effectively in belt filter presses for sludge dewatering, providing high cake solids and low filtrate turbidity. -
Q: What is the maximum operating temperature for continuous use?
A: The cloth can operate continuously at up to 300°C. For intermittent peaks up to 320°C, please consult our technical team. -
Q: How do I choose the right filtration micron rating?
A: The required micron depends on the particle size in your slurry. We recommend a lab test or pilot trial; we can provide samples in 0.5, 1, 2, 3, 5 micron options. -
Q: Is the cloth resistant to acids and alkalis?
A: Polyester has good resistance to dilute acids and alkalis at moderate temperatures. For strong acids or high concentrations, we suggest using a different material (e.g., polypropylene). -
Q: Can you supply the cloth with edge reinforcements or eyelets?
A: Yes, we offer custom edge finishing including heat-cut edges, hemmed edges, and eyelet installation upon request. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, lead time is 5–10 working days. Custom specifications may require 15–20 working days depending on complexity. -
Q: Do you provide free samples?
A: Yes, we can provide free A4-sized samples for evaluation. You only need to cover shipping costs. -
Q: How long is the warranty period?
A: We offer a 12-month warranty against manufacturing defects under normal operating conditions. Extended warranty options are available upon negotiation.
