Double Membrane Biogas Holder for Anaerobic Fermentation Container Tank: Provides the Essential Gas-Tight Roof and Flexible Storage for Fermentation Gases

Double Membrane Biogas Holder for Anaerobic Fermentation Container Tank: Provides the Essential Gas-Tight Roof and Flexible Storage for Fermentation Gases

In modular, decentralized, or containerized waste treatment facilities, the Anaerobic Fermentation Container Tank provides a compact and efficient vessel for converting organic material into stabilized digestate and valuable fermentation gases (biogas). For these high-performance, often high-rate systems to maximize their energy output, the resulting low-pressure gas must be instantly and completely captured, securely sealed, and buffered against production fluctuations. Given the enclosed, often compact nature of container systems, the gas storage solution must function as an essential, integrated component.

The Double Membrane Biogas Holder is the optimal technology for this specialized environment. It provides the essential gas-tight roof and flexible storage for fermentation gases. By forming the flexible dome over the container tank, this holder performs three essential, simultaneous functions: it provides a robust, gas-tight seal, dynamically buffers the fluctuating gas volume and pressure, and ensures continuous, safe operation, all within a compact, integrated footprint perfectly suited for containerized systems.

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 anaerobic fermentation container tanks, offering superior containment, pressure regulation, and long-term durability.

Product Advantages for Containerized Systems

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to maximize the efficiency, safety, and gas recovery of anaerobic fermentation container tanks. The flexible dome design offers distinct advantages for modular and compact plants.

Integrated Gas-Tight Seal and Roof

The primary function of the double membrane holder is to act as an integrated, gas-tight roof for the fermentation tank, which is crucial for preventing the escape of valuable biogas and odors. This hermetic seal is vital for maximizing the energy yield and ensuring compliance with stringent environmental regulations, particularly in urban or confined industrial locations where containerized systems are often deployed. The integrated design minimizes external piping and structural requirements.

Flexible, Low-Pressure Regulation

Gas production from anaerobic fermentation is rarely constant, fluctuating with feedstock quality and biological activity. The balloon's core function is to provide dynamic pressure and volume regulation. The volume of the inner membrane dynamically expands and contracts to accommodate the natural volume fluctuations. This capability acts as a perfect buffer, regulating the head pressure on the digester contents, preventing stress on the tank structure, and ensuring a smooth, stable flow of gas to downstream utilization equipment.

Superior Durability and External Protection

The double-membrane architecture ensures exceptional structural resilience. The outer membrane is inflated with air to form a structurally rigid, protective dome. This outer shell shields the inner gas-holding membrane from external environmental stresses, including high winds, heavy precipitation, and ultraviolet (UV) radiation. The specialized, multi-layered material is also highly resistant to corrosive elements in fermentation gases, guaranteeing a long operational lifespan and low maintenance requirements suitable for continuous operation.
