Double Membrane Biogas Dome – Reliable Gas Storage & Pressure Control

Agastya Double Membrane Biogas Domes provide a reliable and efficient solution for biogas storage, gas pressure control and continuous energy applications. Designed with a durable double-membrane structure, these systems help maintain consistent gas pressure while protecting stored biogas from external weather conditions.

What Is a Double Membrane Biogas Dome and How Does It Work?

A double membrane biogas dome is a flexible gas storage and pressure-control system commonly used with anaerobic digesters. It consists of an inner membrane that stores biogas and an outer membrane that provides structural protection and maintains a controlled air pressure.

Here's the simple genius of the two-layer system:

  • Inner Chamber: Securely holds the biogas.
  • Outer Membrane: Gently pressurized by a small air fan.

This creates a pneumatic push on the inner gas chamber. The result: your biogas is always stored and delivered at a fixed, positive pressure-ready for use.  Additionally, the one-piece factory-welded designeliminates weak points such as joints or anchor leaks, making it more secure and long-lasting than conventional systems.

Key Benefits of Double Membrane Biogas Domes

1. Consistent Gas Pressure & Reliable Performance The pressurized outer membrane helps maintain steady gas pressure, ensuring a consistent biogas supply for generators, boilers and other energy applications
2. High-Capacity Biogas Storage Double membrane biogas domes are suitable for large-scale biogas storage requirements and can be designed according to project capacity and site conditions.
3. Durable & Weather-Resistant Construction Manufactured using high-strength PVC-coated membrane materials, the system is designed to withstand outdoor conditions while providing reliable long-term performance.
4. Enhanced Gas-Tightness & Leak Protection Precision-welded membrane construction provides a secure, gas-tight storage system, helping minimize leakage and maintain efficient biogas containment.
5. Suitable for Different Biogas Applications The system is suitable for biogas plants, anaerobic digesters, industrial facilities, food-processing units and wastewater treatment plants where reliable biogas storage is required.
6. Flexible Design for Different Installations Double membrane biogas domes can be adapted to different site requirements, storage capacities and installation configurations, making them suitable for both new and upgraded biogas facilities.
7. Low Maintenance & Long Service Life The flexible membrane construction requires less structural infrastructure and offers a practical, low-maintenance alternative for modern biogas storage applications.
