Geotextile for Biochemical Tank
Main Functions
1. Geomembrane protection & anti-puncture
Isolate foundation gravel, backfill soil and HDPE liner, avoid sharp particles and hard filler piercing anti-seepage membrane during construction and later sludge backfilling.
2. Isolation and filtration
Block activated sludge, biological sludge and fine silt from sinking into base soil; let excess penetrating water drain away, prevent foundation softening and pipeline blockage.
3. Anti-corrosion & anti-biodegradation
Resist erosion from organic wastewater, biochemical liquid and microbial corrosion inside the biochemical tank, keep stable performance under long-term aeration environment.
Introduction of Geotextile for Biochemical Tank
Biochemical tank geotextile is mostly PP needle-punched staple fiber geotextile, specially matched with HDPE geomembrane lining system for biochemical pool, aeration tank and biological reaction tank of sewage treatment plant.
Ⅰ. Main Functions
1. Geomembrane protection & anti-puncture
Isolate foundation gravel, backfill soil and HDPE liner, avoid sharp particles and hard filler piercing anti-seepage membrane during construction and later sludge backfilling.
2. Isolation and filtration
