What Is a Biogas Holder?
A biogas holder is a gas storage system used to collect, store, and regulate methane-rich biogas generated from anaerobic digestion of organic materials such as:
Livestock manure
Agricultural residues
Municipal sludge
Industrial organic wastewater
Food waste
The primary function of a biogas holder is to:
Stabilize gas pressure
Store excess gas
Ensure continuous supply to generators or boilers
Improve overall system safety
Among various types, the double membrane biogas holder has become the most widely used solution for medium and large-scale projects.
Double Membrane Biogas Holder
Center Enamel’s double membrane biogas holder is engineered for maximum efficiency, safety, and durability.
Structural Design
The system consists of:
Inner Membrane (Gas Storage Layer)
Directly stores biogas
High-strength, gas-tight PVC material
Resistant to methane, CO₂, and H₂S corrosion
Outer Membrane (Protective Layer)
UV-resistant
Weatherproof
Maintains dome structure
Air Support System
Blower maintains constant air pressure between membranes
Stabilizes gas pressure
Ensures consistent gas output
This intelligent structure ensures operational stability and long service life.
