Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in industrial filter fabrics. Our Wet Desulfurization Filter Cloth is engineered specifically for flue gas desulfurization (FGD) systems in power plants. Made from 100% virgin polyester, this filter cloth delivers exceptional chemical resistance, high mechanical strength, and long service life under harsh wet conditions. It effectively removes particulates from gypsum slurry, ensuring optimal desulfurization efficiency and compliance with environmental standards.
Key Features & Benefits
- 100% Virgin Polyester Material – No recycled fibers, ensuring uniform filtration performance and higher durability.
- Excellent Chemical Resistance – Resistant to acidic and alkaline conditions typical in wet FGD processes (pH 2–12).
- High Temperature Tolerance – Continuous operation up to 150°C, suitable for hot flue gas environments.
- Optimized Filtration Efficiency – Precise pore structure captures fine particles (down to 5–10 microns) while maintaining high flux.
- Mechanical Strength – High tensile and burst strength reduce breakage and deformation under pressure and belt tension.
- Anti-Abrasion & Anti-Fatigue – Reinforced weave design extends service life, lowering replacement frequency.
- Customizable Dimensions – Available in various widths (1.0–2.5 m), lengths, and edge treatments (hemmed, spliced, etc.).
- Easy Installation & Maintenance – Lightweight and flexible, compatible with belt filters, drum filters, and vacuum filters.

Application in Power Plants
Our filter cloth is widely used in wet limestone-gypsum desulfurization systems. It serves as the filter medium on belt filters, vacuum filters, and pressure filters to separate gypsum crystals from the slurry. Key advantages include:
- High cake dewatering efficiency – reduces moisture content of gypsum, improving byproduct quality.
- Low blinding tendency – smooth surface minimizes particle adhesion, reducing cleaning frequency.
- Consistent performance – stable filtration rate over long operating cycles.
- Compatibility with existing equipment – can be retrofitted into most standard filter presses and belt filters.

Frequently Asked Questions (FAQ)
1. What is the typical lifespan of this filter cloth in a wet FGD application?
Lifespan depends on operating conditions (temperature, pH, abrasion). Under normal conditions (pH 4–8, temp
2. Can this cloth be used for other filtration applications besides desulfurization?
Yes, it is also suitable for dewatering, chemical filtration, and wastewater treatment where polyester's chemical resistance is required.
3. What is the maximum operating temperature?
Continuous use up to 150°C. For short-term peaks, up to 160°C is acceptable. Exceeding these limits may cause dimensional shrinkage.
4. How do I clean the filter cloth to prevent blinding?
We recommend periodic high-pressure water washing (max 50 bar) or chemical cleaning with mild alkali solutions. Avoid strong oxidizing agents that may damage polyester.
5. Do you offer custom sizes or edge reinforcements?
Yes, we can cut to any width (1.0–2.5 m) and length. Edge treatments include hemmed, spliced, or with grommets as per your request.
6. Is this filter cloth resistant to chlorine or other disinfectants?
Polyester has limited resistance to strong oxidizing agents like chlorine. For FGD applications, the typical slurry does not contain high chlorine levels. If chlorine is present, please consult our technical team for alternative materials.
7. What is the minimum order quantity (MOQ)?
Our standard MOQ is 100 m² per specification. Smaller trial orders are available for sample testing.
8. How is the filter cloth packaged for export?
Each roll is wrapped with protective film, then packed in woven bags or plywood cases to prevent damage during shipping. We can also provide custom packaging upon request.
