Double Membrane Biogas Holder for a Biological Wastewater Treatment Plant: Essential for Collecting Methane Produced by Anaerobic Biological Reactors

Double Membrane Biogas Holder for a Biological Wastewater Treatment Plant: Essential for Collecting Methane Produced by Anaerobic Biological Reactors

A Biological Wastewater Treatment Plant utilizing anaerobic processes (such as UASB, EGSB, or Anaerobic MBR) relies on anaerobic biological reactors to break down high concentrations of organic pollutants. The primary energy co-product of this stabilization process is methane-rich biogas. For the plant to maximize operational efficiency and realize true resource recovery, it is essential for collecting methane produced by these reactors and buffering it for utilization. This ensures a stable fuel supply to offset the plant's significant energy consumption for pumping, mixing, and aeration.

The Double Membrane Biogas Holder is the essential technology for this core function. It is essential for collecting methane produced by anaerobic biological reactors. Installed either as a gas-tight, flexible roof directly on the reactor or as a separate, compact storage unit , this holder provides a dynamic, hermetic reservoir. This system ensures every cubic meter of gas is captured, pressure fluctuations are safely managed, and a stable, continuous supply is maintained for downstream energy utilization, significantly reducing operational costs.

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 within the infrastructure of a biological wastewater treatment plant, offering superior containment, pressure regulation, and long-term durability.

Product Advantages for Biological Reactor Gas Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the continuous and often high gas output typical of large-scale biological digestion processes, maximizing the efficiency and safety of methane recovery.

Reliable Methane Collection and System Protection

The system acts as an integrated gas collection unit over the biological reactor, ensuring maximum gas capture efficiency and preventing methane escape. The inner membrane's volume dynamically expands and contracts to accommodate the natural volume fluctuations in methane production. This acts as a perfect buffer, stabilizing the low pressure and supply of gas to the utilization equipment. This stability is critical for protecting sensitive downstream machinery, such as generators or flares, from damaging pressure spikes or drops.

Fugitive Emission and Odor Control

Beyond energy recovery, the system provides a crucial hermetic seal over the reactor. This is paramount for fugitive emission control (preventing the release of methane, a potent greenhouse gas) and for significantly reducing odor emissions associated with anaerobic biological processes. The gas-tight integrity ensures compliance with strict environmental regulations.

Support for Aluminum Dome Roofs

Where maximum structural integrity is required—for example, when supporting heavy auxiliary equipment or facing harsh weather conditions—the Double Membrane Holder can be installed on or adjacent to a tank protected by an Aluminum Dome Roof . While the membrane system provides the flexible gas-tight envelope, the aluminum dome offers superior long-term corrosion protection and structural support for the entire digester tank structure, enhancing overall system durability.
