Detailed Product Description
Our sand washing sludge dewatering filter cloth is meticulously woven to achieve a precise 0.5mm opening, ensuring that fine sand particles and sludge solids are effectively captured while allowing clear water to pass through. This level of precision is critical in sand washing operations where product quality and water recovery are paramount. The cloth is available in multiple weave patterns, each offering different characteristics: plain weave for maximum stability, twill weave for balanced filtration and cake release, and satin weave for smoother surface and reduced blinding.
The material selection—polyester or polypropylene—depends on the chemical environment and temperature of your process. Polyester offers excellent dimensional stability and resistance to organic acids, while polypropylene provides superior alkali resistance and low cost. Both materials are FDA-compliant for indirect food contact (optional). The cloth can be treated with anti-static or anti-stick coatings upon request.
One of the standout features of this product is the inclusion of a mill test report. For each production batch, we conduct tests for pore size distribution, tensile strength (warp and weft), elongation, and air permeability. The report is provided with your shipment, allowing you to verify conformity before installation. This transparency is especially valued by quality-conscious buyers in North America and Europe.
The 1-year warranty covers any manufacturing defects such as yarn breakage, uneven weave, or premature wear under normal operating conditions. Should any issue arise, our team offers prompt replacement or credit. We also provide technical support for installation and troubleshooting, leveraging our 25+ years of experience in wire mesh and filter cloth production.

Frequently Asked Questions (FAQ)
-
Q: What is the exact filtration precision of this cloth?
A: The nominal precision is 0.5mm, meaning the average opening size of the weave is 0.5mm. Actual pore size may vary slightly depending on weave type and tension. The mill test report provides measured values for each batch. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (shipping cost may apply) for evaluation. Sample size is typically 30cm x 30cm or a small roll. Please contact our sales team to arrange. -
Q: What is the lead time for production?
A: For standard widths and materials, lead time is 10–15 working days after order confirmation. Custom specifications may require 20–25 working days. Urgent orders can be expedited upon request. -
Q: Is this cloth suitable for acidic or alkaline environments?
A: Polyester is suitable for acidic environments (pH 2–7) but not for strong alkalis. Polypropylene is ideal for alkaline conditions (pH 7–14) and is also resistant to many organic solvents. Please specify your chemical conditions when ordering. -
Q: How is the cloth packaged for export?
A: Each roll is wrapped in polyethylene film, then placed in a woven bag or carton. For larger orders, rolls are palletized and strapped. We can also provide custom packaging per your requirements. -
Q: Does the 1-year warranty cover wear and tear?
A: The warranty covers manufacturing defects only, not normal wear and tear, misuse, or improper installation. If you experience premature failure (e.g., tearing at seams within 6 months), we will replace or refund the defective portion. -
Q: Can I choose different edge finishes?
A: Yes, we offer selvedge edges, hemmed edges with tape, or fused edges. The choice depends on your filter press or belt filter type. Please advise your machine parameters for recommended finish. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is 100 square meters for standard items. Custom orders may have higher MOQ based on production feasibility. We are flexible for trial orders.
