Double Membrane Biogas Holder for an Industrial Wastewater Treatment Plant: Captures and Stores Biogas Generated During Anaerobic Effluent Treatment

Double Membrane Biogas Holder for an Industrial Wastewater Treatment Plant: Captures and Stores Biogas Generated During Anaerobic Effluent Treatment

An Industrial Wastewater Treatment Plant faces the challenge of managing diverse, high-strength effluents resulting from manufacturing processes, including food and beverage production, chemical refining, and textile dyeing. The most effective strategy for both environmental compliance and resource recovery is anaerobic digestion (AD), which stabilizes the industrial effluent while generating a substantial amount of methane-rich biogas. For the plant to maximize the economic and environmental benefits of its operations, the biogas must be reliably and securely captured and stored before being utilized for energy production to offset the plant’s significant power demands. The storage solution must be integrated, highly efficient at capture, and durable enough to withstand the demanding, corrosive environment of industrial gas recovery.

The Double Membrane Biogas Holder is the optimal technology for this critical industrial application. It captures and stores biogas generated during anaerobic effluent treatment. Installed either as an integrated flexible roof on the digester or as a compact, free-standing 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 utilization (e.g., boilers or CHP units), effectively turning a waste liability into a core energy asset for the industrial facility.

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 an industrial wastewater treatment plant, offering superior containment, pressure regulation, and long-term durability.

Product Advantages for Industrial Gas Recovery and Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to maximize the efficiency, safety, and operational control of biogas systems handling complex industrial effluent.

Integrated Gas Capture and Supply Stability

The system acts as an integrated, gas-tight seal over the anaerobic reactor, ensuring maximum gas capture efficiency by collecting the gas instantly. The inner membrane's volume dynamically expands and contracts to accommodate the natural volume fluctuations in biogas production inherent in varying industrial schedules. This acts as a perfect buffer, stabilizing the low pressure and supply of gas to the utilization equipment. This stability is critical for continuous industrial operation, maximizing the use of renewable energy generated from the waste.

Resilience to Corrosive Industrial Gas

Biogas generated from industrial effluent is typically high in moisture and can contain various corrosive trace elements. The balloon is constructed from specialized, multi-layered composite fabric, which is selected for its exceptional durability and resistance to corrosive elements. This resistance is crucial for the long-term integrity of the gas-tight seal, ensuring reliable operation, minimizing fugitive methane emissions, and reducing maintenance costs in this challenging industrial environment.

Support for Aluminum Dome Roofs (When Applicable)

In cases where a concrete or steel digester tank requires supplementary corrosion protection or an alternative support structure, the Double Membrane Holder can be paired with an existing or new tank that utilizes an Aluminum Dome Roof for structural integrity. While the membrane system provides the flexible gas-tight envelope, the aluminum dome can offer structural support and weather protection for other elements of the reactor, demonstrating the flexibility and compatibility of our systems with diverse tank designs.
