In the world of anaerobic digestion, methane digester tanks are fundamental to converting organic waste into a renewable energy source. The success of this process hinges on a reliable, gas-tight cover that can effectively contain the valuable biogas and protect the integrity of the system. While sophisticated dual-membrane systems have their place, a simpler, highly efficient, and cost-effective solution is often the ideal choice for many projects: the Single Membrane Roof. This technology serves as an excellent cover for methane digester tanks, providing superior containment and durability with a straightforward design. As a premier China Single Membrane Roof Manufacturer, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is at the forefront of providing these essential solutions, optimizing performance and safety in biogas facilities worldwide.
With a legacy of over three decades in providing specialized containment systems, Center Enamel’s expertise as a China Single Membrane Roof Manufacturer is built on a deep understanding of the practical needs of biogas projects. Our commitment to advanced material science and precision engineering ensures that our solutions are not just products, but integral components that enhance the longevity and efficiency of biogas facilities. The simple yet robust design of our Single Membrane Roof offers an indispensable cover solution, providing superior gas containment and protection that secures the integrity of your Methane Digester Tanks and maximizes the value of your renewable energy investment.
A Single Membrane Roof is a straightforward, low-pressure cover solution designed to fit seamlessly on top of methane digester tanks. Its primary function is to provide a complete, gas-tight seal over the tank’s contents, capturing biogas as it is produced. Unlike a double-membrane system, which integrates storage, the single membrane roof is primarily a cover with a central gas outlet for collection. This simplicity makes it a highly economical and practical choice for many applications.
The key features of a single membrane roof include:
Gas-Tight Seal: The membrane is fabricated from a high-strength, gas-tight material, typically PVC-coated polyester fabric. This material is resistant to the corrosive compounds in biogas and creates a secure seal to prevent methane emissions and odor leakage.
Weather Protection: The robust material provides excellent protection from external elements like rain, wind, and UV radiation, shielding the digester's contents and ensuring the longevity of the tank.
Gas Collection Point: The single membrane roof is engineered with a central gas outlet, allowing biogas to be efficiently collected and routed to a separate storage system or a downstream process like a gas generator or purification unit. This design maintains a constant, low-pressure environment within the tank.
Simple Tensioning System: The roof is securely anchored to the top flange of the methane digester tanks using a tensioning system. This ensures the membrane remains taut and stable, preventing it from sagging or fluttering in the wind.
This straightforward design ensures that the single membrane roof provides all the essential functions of a tank cover—containment, protection, and gas collection—in a highly reliable and cost-effective package.
Our Single Membrane Roof offers a range of significant advantages that make it a superior cover solution for Methane Digester Tanks:
Exceptional Cost-Effectiveness: The simplified design and construction of a single membrane roof make it a highly economical option compared to more complex double-membrane or rigid cover systems. This helps to reduce initial capital expenditure and improves the overall return on investment for biogas projects.
Durability and Longevity: Fabricated from corrosion-resistant and UV-stabilized materials, our single membrane roofs are built to endure the harsh internal environment of biogas production and the external pressures of weather. They are designed for a long operational life with minimal maintenance.
Superior Gas Containment: The gas-tight seals and robust membrane material ensure that all biogas is effectively contained. This prevents the release of methane, a potent greenhouse gas, and eliminates unpleasant odors, making it a highly effective and environmentally responsible cover solution.
Simplified Installation and Maintenance: The lightweight and modular nature of our single membrane systems facilitates quick and straightforward on-site assembly, significantly reducing construction time and labor costs. Its simple design also means there are fewer components to maintain over its operational lifespan.
Versatility: The single membrane roof can be custom-tailored to fit a wide range of tank dimensions and is suitable for various applications, from small-scale agricultural digesters to large industrial facilities.

Inner Mongolia Bio-Natural Gas Project, China:
Application: Our membrane roofs were installed as simple, yet effective covers for the anaerobic methane digester tanks at this large-scale bio-natural gas plant. They were instrumental in providing a completely sealed environment for the digestion process and directing the biogas to the plant's separate gas holders and purification systems.
Project Case: This bio-natural gas project in Inner Mongolia utilized 4 units of our membrane roofs with a total gas collection area that effectively covered the methane digester tanks, ensuring efficient biogas capture before it was purified and compressed.
Henan Province Bioenergy Project, China:
Application: At this bioenergy project that utilizes animal waste, our single membrane roofs were installed as the covers for the methane digester tanks. The covers allowed the tanks to function as efficient Continuous Stirred Tank Reactors (CSTRs) by maintaining an ideal anaerobic environment, while the gas was continuously collected for energy use.
Project Case: A major bioenergy project in Henan province utilized several Glass-Fused-to-Steel tanks with a total volume of 4,407m³. Our single membrane roofs were installed as the covers, enabling the tanks to effectively serve as a reliable platform for biogas production.
Shandong Heze Biogas Project, China:
