In the world of renewable energy and organic waste management, digester tanks are the heart of any biogas production facility. These sealed vessels provide the ideal environment for anaerobic digestion, a process that converts waste into valuable biogas. However, the success and safety of this process hinge on a reliable and efficient cover and gas storage system. The Double Membrane Biogas Storage Balloon has emerged as the definitive solution, serving not only as a hermetic cover for digester tanks but also as an integrated, low-pressure gas holder. This all-in-one system is a critical component that ensures optimal performance and safety. As a leading China Double Membrane Biogas Storage Balloon Manufacturer, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is dedicated to providing these high-quality solutions, driving efficiency and sustainability in biogas projects worldwide.
With more than 30 years of experience in specialized tank and cover solutions, Center Enamel has established itself as a global authority. Our expertise as a premier China Double Membrane Biogas Storage Balloon Manufacturer is rooted in a deep understanding of the anaerobic digestion process, a commitment to advanced material science, and a focus on precision engineering. The design of our Double Membrane Biogas Storage Balloon is meticulously optimized to secure the contents of digester tanks, providing a dynamic and safe storage buffer that maximizes energy output and operational reliability. By integrating a storage solution directly onto the digester, we offer a streamlined and highly cost-effective path toward a cleaner, more sustainable energy future.
A Double Membrane Biogas Storage Balloon is a sophisticated, low-pressure system engineered to seamlessly integrate with digester tanks. Its innovative design combines a cover and a storage unit, eliminating the need for separate high-pressure tanks and complex piping. The system is constructed from robust, gas-tight membrane material, a PVC-coated polyester fabric known for its exceptional durability and resistance to the corrosive gases and UV exposure found in biogas environments.
The key components of this dual-layer system are:
Inner Membrane: This flexible membrane forms the primary gas containment chamber and acts as the direct cover for the tank. It is designed to expand and contract dynamically, buffering fluctuations in biogas production and preventing dangerous pressure buildups or vacuums within the digester tanks. This continuous adaptability is crucial for protecting the structural integrity of the entire system.
Outer Membrane: This permanently inflated, dome-shaped external layer provides structural stability and protection. Maintained under a slight positive air pressure by a low-pressure blower, it shields the inner membrane and the stored biogas from extreme weather conditions, including wind, snow, and rain. The insulated air gap between the two membranes helps to regulate the temperature of the stored gas, which is vital for maintaining the optimal conditions for microbial activity inside the digester.
This unique dual-membrane system guarantees absolute gas-tightness, effectively capturing all valuable biogas and mitigating fugitive methane emissions. It is a fundamental component for modern, high-performance biogas facilities.
Our Double Membrane Biogas Storage Balloon offers a range of significant benefits that make it an essential addition to any biogas facility with digester tanks:
Enhanced Operational Safety: Operating at a very low pressure, these balloon systems are an inherently safer alternative to high-pressure gas storage. This design choice minimizes the risk of explosion and provides peace of mind for plant operators. The integrated pressure management within the dual membranes further enhances overall safety.
Thermal Regulation and Efficiency: The air layer between the membranes acts as an effective insulator. This thermal barrier helps maintain a stable, warm temperature within the digester tanks, which is essential for maximizing the efficiency and yield of the anaerobic digestion process, especially in cooler climates.
Simplified Installation and Cost Savings: Our balloons are lightweight and modular, allowing for quick and straightforward installation directly on top of new or existing digester tanks. This integrated approach significantly reduces the need for expensive external gas tanks and associated infrastructure, leading to lower capital and construction costs.
Superior Durability and Longevity: Fabricated from premium, corrosion-resistant, and UV-stabilized materials, our biogas storage balloons are built to last. They can endure the harsh internal environment of biogas production and the external pressures of weather, ensuring a long operational life with minimal maintenance.
Effective Emission and Odor Control: The hermetically sealed design prevents the release of methane, a potent greenhouse gas, and effectively contains unpleasant odors. This not only makes the plant more environmentally friendly but also improves community relations.

Inner Mongolia Bio-Natural Gas Project, China:
Application: Our biogas balloons were installed as the covers for the anaerobic digester tanks at this large-scale bio-natural gas plant. They were instrumental in providing a hermetically sealed environment for the digestion process and a crucial low-pressure buffer for gas collection before it was sent to the purification and compression systems.
Project Case: This bio-natural gas project in Inner Mongolia utilized 4 units of our balloons, providing a total storage volume of 16,760m³ atop the digester tanks.
Henan Province Bioenergy Project, China:
Application: As part of a bioenergy project that utilized animal waste, our balloons were installed as the tank covers. This allowed the digester tanks to function as efficient Continuous Stirred Tank Reactors (CSTRs) by maintaining an ideal anaerobic environment, while simultaneously acting as the primary storage vessel for the biogas produced.
Project Case: A major bioenergy project in Henan province utilized several Glass-Fused-to-Steel tanks with a total volume of 4,407m³. Our double membrane biogas balloons were installed as the covers, enabling the tanks to effectively serve as both digesters and gas storage units.
