Geotextile for Equalization Tank

Introduction of Geotextile for Equalization Tank
Geotextile for equalization tank is mainly needle‑punched staple fiber PP geotextile, widely laid inside wastewater regulating tanks, buffer ponds and equalization basins of sewage treatment plants, matched with HDPE geomembrane lining system.

1. Main Functions
·Isolation Protection
Separate base soil, gravel bedding and HDPE liner, prevent sharp stones and coarse soil from puncturing the impermeable geomembrane during backfilling and construction.
·Filtration & Anti‑clogging
Block suspended sludge and fine sediment inside wastewater from penetrating into the underlying foundation, allow seepage water to drain smoothly, avoid foundation mud pumping and pond bottom silt blocking drainage pipelines.
·Stress Dispersion & Reinforcement
Evenly distribute foundation settlement stress and water load, reduce local stress concentration on geomembrane, slow down liner cracking caused by uneven subsidence.
·Anti‑corrosion
Resist erosion from acidic, alkaline and oily wastewater in regulating tank, stabilize long‑term operation of the tank lining system.

2. Common Specification
·Conventional weight: 300gsm staple fiber geotextile for membrane bottom isolation; 400~600gsm filament geotextile for membrane top protection on steep slope.
·Material: PP polypropylene staple fiber (dominant for equalization tank due to superior chemical resistance against sewage).
·Standard width: 4m / 5m / 6m, roll length: 50m /100m.

3. Application Scenarios
·Municipal sewage plant wastewater equalization tank
·Industrial wastewater regulating pond (chemical, printing, food processing wastewater)
·Buffer balancing lagoon for integrated sewage treatment station

4. Product Features
Excellent acid & alkali resistance, stable filtration performance, flexible for bending and laying, easy cutting and on-site construction, cost-effective for large-area tank projects.
