Biogas Membrane Manufacturers – Gas-Tight Membranes for Anaerobic Digesters
DERFLEX is a professional biogas membrane manufacturer offering high-performance PVC & TPU coated membranes engineered for methane containment, durability, and reliable long-term performance across agricultural, industrial & landfill biogas systems.
What is a Biogas Membrane?
A biogas membrane is a flexible, gas-tight liner used to encapsulate methane-producing anaerobic digesters, biogas plants, and waste management systems. Engineered from high-grade PVC / TPU coated fabrics, these membranes provide superior gas impermeability, UV stability, chemical resistance, and long service life, ensuring optimal methane capture and safe operation for biogas systems worldwide.
Key Features & Advantages
- Superior Gas-Tightness: Engineered to prevent methane leakage and ensure efficient biogas capture.
- UV & Weather Resistant: Durable coatings protect against sunlight, oxidation, and harsh environmental conditions.
- Customizable Design: Thickness, width, coating material (PVC or TPU), and colors can be tailored to project needs.
- High Mechanical Strength: Excellent tensile and tear resistance for large digesters and outdoor installations.
- Low Maintenance: Once installed, requires minimal upkeep, reducing lifecycle costs.
- OEM & ODM Support: DERFLEX offers full custom manufacturing for specialist biogas projects.
