Geotextile for Sewage Ponds
Key Functions
Separation: Isolate soil, gravel, geomembrane and sludge to prevent layer mixing.
Filtration: Permit water passage while blocking sediment and sludge, avoiding drainage clogging.
Protection: Prevent HDPE geomembrane from puncture, friction and extrusion.
Drainage & Pressure Relief: Divert accumulated water and reduce hydrostatic pressure on the lining.
Reinforcement: Distribute load evenly, reduce settlement and improve structural stability.
Introduction to Geotextile for Sewage Ponds
1. Product Overview
Sewage pond geotextile is a needle-punched nonwoven fabric made of polyester or polypropylene. It is an essential supporting material for the anti-seepage system of sewage ponds, regulating tanks, biochemical tanks and sludge drying fields. Featuring excellent acid and alkali resistance, corrosion resistance and microbial resistance, it is normally used together with HDPE geomembrane, widely applied in municipal and industrial wastewater treatment projects.
2. Main Types & Features
Polyester filament geotextile: High tensile strength, good anti-aging performance and long service life, ideal for large-scale deep sewage ponds and side slopes.
Polyester staple fiber geotextile: Uniform filtration and cost-effective, the general choice for conventional sewage projects.
Polypropylene staple fiber geotextile: Outstanding chemical resistance, suitable for industrial sewage with strong corrosivity.
