Industrial filter fabric for wastewater treatment

Application

Wastewater & Effluent Treatment

Reliable filter fabrics for municipal and industrial sludge dewatering, ETP effluent treatment, and process water recovery. Engineered for consistent performance, low maintenance, and regulatory compliance across all wastewater applications.

The Challenge

Wastewater treatment plants operate around the clock, processing millions of litres of sewage, industrial effluent, or process water daily. The sludge generated during treatment must be dewatered efficiently before disposal or further processing — and the filter fabric is at the heart of this operation.

Sludge composition varies widely: biological sludge is sticky and compressible, while industrial sludge may contain oils, chemicals, or fine inorganic particles. The filter fabric must handle these variations while maintaining consistent cake dryness and filtrate clarity to meet discharge standards.

Typical Wastewater Filtration Tasks

Municipal sewage sludge dewatering
Industrial effluent treatment plant (ETP) sludge
Activated sludge and biological sludge processing
Chemical sludge dewatering (precipitation / flocculation)
Textile and dye effluent treatment
Food and beverage wastewater processing
Paper mill effluent sludge filtration
Pharmaceutical and chemical ETP sludge
Electroplating and metal finishing effluent
Zero Liquid Discharge (ZLD) pre-treatment

Key Fabric Requirements

Wastewater sludge demands specific fabric properties to ensure reliable operation.

Cake Release

Biological sludge is notoriously sticky. Easy-release coatings and monofilament surfaces ensure clean discharge without manual intervention.

Dewatering Efficiency

Achieving target dry solids content (25-40%) reduces disposal volume and transport costs. Optimised pore structures maximise water removal.

Chemical Resistance

Polymer conditioning agents, pH fluctuations, and cleaning chemicals require fabrics that maintain integrity over extended periods.

Anti-Blinding Design

Compressible biological sludge can quickly blind standard fabrics. Controlled pore geometry and surface treatments maintain throughput.

Filtrate Quality

Meeting discharge limits requires consistent particle retention across all operating conditions and cloth age.

Low Maintenance

Wastewater plants run 24/7 with limited maintenance windows. Long-lasting fabrics with easy washability reduce operational burden.
