Free Standing Double Membrane Gas Holder For Sewage Water Treatment Plants
MONDES's Free Standing Double Membrane Biogas Storage Tanks are manufactured from advanced structural fabrics engineered to meet rigorous environmental demands. These membrane tanks provide structural stability and impermeable gas storage, maximizing efficiency and safety in biogas management.
The innovative design eliminates metal components except for the anchorage to concrete foundations, minimizing corrosion risks and enhancing durability. Our tanks feature comprehensive instrumentation systems for precise measurement and control of pressure, temperature, and gas composition.
These versatile biogas storage tanks serve multiple applications:
- Solid waste processing facilities for organic material digestion
- Sewage water treatment plants for methane capture
- Agricultural waste treatment projects for renewable energy production
- Industrial-scale emissions reduction solutions
Structural Features- Constructed from high-strength polyester fiber film with excellent flexibility and tensile strength
- Adaptive deformation accommodates gas volume variations and operational pressures
- Lower foundation requirements compared to conventional steel tanks
- Inner membrane for gas storage with protective outer membrane
- Automatically regulated interstitial air layer maintains shape stability
- Dynamic pressure adjustment ensures consistent operational performance
- Reduced mass minimizes foundation demands
- Simplifies installation and relocation processes
- Lowers project costs and timelines
