Double Membrane Biogas Holder for Fermentation Tanks: A Secure, Flexible Cap Used to Capture and Contain Fermentation Gases

Double Membrane Biogas Holder for Fermentation Tanks: A Secure, Flexible Cap Used to Capture and Contain Fermentation Gases

In numerous industrial and waste-to-energy processes, the Fermentation Tank is the vessel where organic matter is biologically broken down. Whether dealing with food waste, agricultural residues, or industrial organic streams, the tank's core function is to facilitate the biological conversion that yields useful byproducts, including a range of fermentation gases. For the process to be successful and safe, these gases must be efficiently and hermetically captured and contained. Given that gas production is typically low-pressure, variable, and continuous, the storage solution must act as a secure, flexible cap over the tank to manage these fluctuations while maximizing gas recovery.

The Double Membrane Biogas Holder is the essential technology that serves this role. It is a secure, flexible cap used to capture and contain fermentation gases. Installed directly onto the fermentation tank, this holder provides a durable, gas-tight seal and a dynamic reservoir. This dual functionality ensures that all generated gas is contained, the tank pressure is regulated safely, and the valuable fuel is buffered for stable utilization, making it an indispensable part of any high-efficiency fermentation system.

Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in advanced containment solutions, specializes in engineering high-performance storage systems. Our Double Membrane Biogas Holders are state-of-the-art gas holders designed to integrate seamlessly with various fermentation tanks, offering superior containment, pressure regulation, and long-term durability.

Product Advantages of the Secure, Flexible Cap

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to maximize the efficiency, safety, and gas recovery of fermentation tanks. The flexible cap design provides distinct advantages for various fermentation processes.

Hermetic Seal and Gas-Tight Capture

The double membrane holder acts as a crucial hermetic seal for the fermentation tank, preventing the escape of valuable gases and odors into the environment. This gas-tight capture is vital for maximizing the energy yield and ensuring environmental compliance. The inner membrane securely contains the gas, while the outer membrane is inflated to provide structural stability, effectively creating a completely closed system directly over the fermentation process.

Flexible, Low-Pressure Regulation

Gas production from fermentation is rarely constant; it fluctuates with temperature, feedstock quality, and biological activity. The balloon's design provides a flexible, low-pressure reservoir that can dynamically expand and contract to accommodate these volume and pressure fluctuations. This acts as a perfect buffer, regulating internal pressure to prevent stress on the tank structure and ensuring a smooth, stable flow of gas to downstream utilization or scrubbing equipment.

Durability and External Protection

The robust, double-membrane architecture ensures exceptional resilience, which is particularly important for systems exposed to the elements. The outer membrane is air-supported to form a rigid, protective dome that shields the inner gas-holding membrane from external environmental stresses, including high winds, heavy precipitation, and ultraviolet (UV) radiation. This proven durability, combined with the material’s resistance to internal corrosive elements, leads to low maintenance requirements and a long operational lifespan.
