Cleaning Water, Preserving Color – Advanced Filtration for the Textile Industry

Dyeing and printing factories are achieving remarkable advancements in wastewater treatment through the adoption of specialized Polyester Sludge Dewatering Mesh Belt. These innovative belts are engineered to handle the highly corrosive and chemically complex effluents typical of textile dyeing processes, delivering superior dewatering performance, enhanced filtration efficiency, and extended operational lifespan.

Engineered for Corrosion and Chemical Resistance

Dyeing and printing operations generate wastewater laden with dyes, pigments, heavy metals, salts, acids, alkalis, and organic solvents—presenting unique challenges for conventional filtration systems. The Polyester Sludge Dewatering Mesh Belt is designed to withstand these harsh conditions while maintaining structural integrity and filtration consistency.

A.      Chemical Resilience: Exceptional resistance to acidic, alkaline, and saline environments (pH 1–14)

B.      Dye and Pigment Resistance: Prevents clogging and fouling from suspended colorants and printing pastes

C.      Thermal Stability: Maintains performance in high-temperature wash and treatment cycles

D.      Abrasion Resistance: Withstands abrasive particles and fibrous sludge common in textile effluent

1.      Superior Dewatering and Filtration Performance

A.      High Solids Capture: Achieves up to 99% solids retention for sludge with high dye and chemical content

B.      Rapid Water Drainage: Polyester Sludge Dewatering Mesh Belt Open-mesh design accelerates dewatering, reducing cycle times by up to 40%

C.      Consistent Cake Dryness: Produces sludge cakes with solids content exceeding 35%, minimizing disposal volume and cost

D.      Easy Cake Release: Non-stick surface ensures clean separation, reducing belt cleaning frequency

2.      Operational and Economic Benefits

A.      Extended Belt Life: Polyester Sludge Dewatering Mesh Belt 3–4 times longer lifespan than conventional belts in corrosive textile environments

B.      Energy Efficiency: Reduces power consumption in dewatering presses and filtration systems

C.      Low Maintenance: Resists blinding and fouling, decreasing downtime for cleaning and replacements

D.      Regulatory Compliance: Helps factories meet stringent discharge standards for color, COD, BOD, and heavy metals

3.      Environmental and Sustainability Impact

A.      Water Reuse Enablement: Produces clearer filtrate suitable for recycling in dyeing and washing processes

B.      Reduced Sludge Volume: Polyester Sludge Dewatering Mesh Belt Cuts disposal costs and environmental footprint

C.      Chemical Recovery Potential: Supports recovery of dyes and auxiliaries from separated sludge

4.      Polyester Sludge Dewatering Mesh Belt Technical Specifications

A.      Material: Corrosion-resistant polyester monofilament with optional protective coating

B.      Mesh Size: 0.05–1.0 mm, customizable based on sludge particle size

C.      Width & Length: Tailored to fit belt filter presses, screw presses, and rotary drum filters

D.      Tensile Strength: ≥ 180 kN/m

E.      Temperature Tolerance: –20°C to 130°C

Industry Validation

A leading textile dyeing factory reported: “After integrating the Polyester Mesh Sludge Dewatering Belt, we achieved a 50% increase in daily sludge processing capacity and a 60% reduction in belt replacement frequency. The chemical resistance has been exceptional—even with reactive dyes and acidic discharges.”
