Project Type: Rural Livestock Waste Biogas Engineering
Location: Shandong, China
Scale: 5 sets of 500m³ biogas digesters (full-set sealing solution)
Core Demand: Solve biogas & slurry leakage, ensure long-term stable operation, realize waste recycling
The project adopted our 1.5mm HDPE geomembrane (meets GB/T 17643-2011 & international standards). It’s the first choice for biogas engineering due to 4 core advantages:
Zero Leakage Guarantee: Ultra-low permeability coefficient, completely isolates biogas and corrosive slurry, avoiding soil & groundwater pollution.
Strong Corrosion Resistance: Resists acid, alkali and organic substances in biogas slurry, service life up to 30+ years.
Anti-Deformation & Tear-Proof: High tensile strength and elongation, adapts to foundation settlement without cracking.
Fast & Reliable Construction: Hot-melt welding, high efficiency; weld seam qualification rate 100% after inspection.
1. Foundation leveling & compaction (remove sharp objects to protect membrane).
2. Geomembrane laying (overlap width ≥10cm, no wrinkles).
3. Hot-melt welding & seam pressure test.
4. Full-scale leak detection (vacuum box + spark test, 100% qualified).
Sealing Performance
No leakage at all; biogas production efficiency reaches 0.6m³/(m³·d), 20% higher than traditional concrete digesters.
Economic Benefit
Supplies cooking/heating for 200 rural households; biogas residue as organic fertilizer, cutting energy costs.
Environmental Benefit
Breeding waste is fully recycled; discharged slurry meets agricultural irrigation standards.
Our HDPE geomembrane has been widely used in biogas projects of different scales (household, village, large breeding base). Custom thickness (1.0-3.0mm) & size available. Contact us now to get your free sample and a tailored solution that complies with Philippine local standards!
