What Is a Biogas Membrane?
A biogas membrane is a flexible gas-tight industrial membrane used to contain methane-rich gas, protect digestion systems and separate biogas environments from external exposure.
Designed for Biogas Containment
Biogas membranes are used in anaerobic digesters, biogas gas holders, lagoon covers, gas storage bags and landfill gas collection systems. The membrane must provide gas tightness, strong seams, chemical resistance, outdoor durability and stable performance under changing temperatures.
More Than a Simple Liner
A reliable biogas digester liner is not only about thickness. It also requires a suitable base fabric, coating formula, welding compatibility, gas permeability direction, UV resistance, tear strength, anchoring design and long-term project support.
Key Features & Benefits
DERFLEX biogas membrane is engineered for gas containment, outdoor operation, welding performance and long-term project reliability.
Gas-Tight Performance
Low gas permeability direction helps reduce methane loss and supports safer biogas storage or digester operation.
Weldable Construction
PVC and selected TPU membrane structures can be welded into larger panels using suitable hot-air, wedge or high-frequency welding methods.
UV & Weather Resistance
Outdoor biogas plants require resistance to sunlight, rain, wind, temperature variation and long-term aging.
Chemical Resistance
Biogas environments may involve hydrogen sulfide, organic acids, condensate and microbial exposure, so material selection must match project chemistry.
High Tensile Strength
Reinforced polyester or technical fabric base supports tear resistance, load distribution, anchoring stability and dimensional control.
Customizable Structure
Thickness, fabric weight, width, color, coating, reinforcement, panel size and packaging can be customized for specific biogas projects.
PVDF Surface Option
PVDF surface treatment can be considered for improved cleanability, weathering protection and premium outdoor surface durability.
OEM / ODM Supply
DERFLEX supports membrane fabricators, biogas system builders, EPC contractors and distributors with repeatable custom specifications.
Project Consultation
Buyers can send project size, application, material requirements and operating conditions for material recommendation support.

Proper installation is critical for gas tightness, seam integrity and long-term service life.
Prepare the Base
Make sure the base surface is smooth, clean and free from sharp stones, metal fragments, debris or uneven stress points.
Use Correct Welding
Select the correct welding method for PVC or TPU membrane and confirm welding parameters before field installation.
Protect the Membrane
Use protective layers, anchoring systems, drainage design or geotextile cushioning where required by the project.
Inspect and Maintain
Check seams, anchors, folds, exposed areas and gas-tight zones regularly to extend the membrane service life.

What is a biogas membrane?
A biogas membrane is a gas-tight flexible membrane used in anaerobic digesters, biogas plants, gas holders, biogas bags, lagoon covers and landfill gas collection systems. It helps contain methane-rich biogas and protect the digestion or storage system.
What is the difference between PVC and TPU biogas membranes?
PVC coated fabric is cost-effective, weldable and widely used in many biogas projects. TPU coated fabric may provide better flexibility, chemical resistance and gas barrier direction for demanding applications. The best choice depends on chemical exposure, pressure, temperature and project design.
Can DERFLEX supply custom sizes for large-scale digesters?
Yes. DERFLEX supports custom width, length, thickness, weight, color, coating structure, reinforcement and packaging for farm digesters, industrial biogas plants and large anaerobic digestion projects.
Can the membrane be welded on site?
Yes, many PVC and TPU coated membrane structures can be welded using suitable welding equipment and parameters. Field welding should be performed by qualified installers according to project specifications.
How does DERFLEX control biogas membrane quality?
DERFLEX can support quality control through raw material inspection, coating uniformity checks, tensile and tear strength testing, surface inspection, roll inspection, gas barrier direction control and welding compatibility review.
How should the membrane be stored before installation?
Store membrane rolls in a cool, dry and shaded warehouse. Avoid direct sunlight, high temperature, sharp edges, heavy pressure, chemical exposure and long outdoor storage before installation.
What information should I send for a quote?
