Double Membrane Biogas Holder for a Pig Farm Plant: A Strong Solution for Collecting Gas Generated by Concentrated Pig Manure Treatment

Double Membrane Biogas Holder for a Pig Farm Plant: A Strong Solution for Collecting Gas Generated by Concentrated Pig Manure Treatment

Pig farm plants, particularly large-scale operations, generate vast quantities of concentrated pig manure and wastewater. The sustainable and responsible treatment of this waste stream relies heavily on anaerobic digestion (AD), which converts the manure into stabilized digestate and valuable, methane-rich biogas. Given the high solids content and volume of the feedstock, the resulting biogas flow is substantial and often corrosive. The system must be a strong solution for collecting gas that is generated continuously and must be durable enough to withstand the demanding environment of concentrated manure treatment.

The Double Membrane Biogas Holder is the optimal technology for this environment. It is a strong solution for collecting gas generated by concentrated pig manure treatment. Installed either as an integrated flexible roof on the digester or as a compact, free-standing unit, this holder provides a durable, air-supported structure that not only creates a robust, gas-tight seal but also offers a dynamic, low-pressure reservoir. This integrated design ensures every cubic meter of gas is captured, pressure fluctuations are safely managed, and the pig farm achieves greater energy self-sufficiency and environmental compliance.

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 pig farm plant, offering superior gas containment, pressure regulation, and long-term durability.

Product Advantages for Concentrated Manure Treatment

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the specific requirements of biogas derived from concentrated pig manure, maximizing the efficiency and safety of large-scale AD systems.

Strength and Resilience to Corrosive Gas

Biogas generated from concentrated pig manure is notoriously corrosive due to its moisture content and various 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 chemical resistance is crucial for the long-term integrity of the gas-tight sealing, maximizing the collection of the valuable methane gas and minimizing wear and tear in the harsh environment above the slurry. The strong fabric and reinforced seams ensure structural longevity.

Integrated Gas Capture and Supply Stability

The system acts as the integrated flexible roof of the digester tank, ensuring maximum gas capture efficiency by collecting the gas instantly. The inner membrane's volume dynamically expands and contracts to accommodate the natural fluctuations in biogas production inherent in manure digestion. This acts as a perfect buffer, stabilizing the pressure and supply of gas to the farm’s utilization equipment (e.g., boilers or engines), ensuring reliable, continuous energy output and maximizing the value of the collected methane.

Fugitive Emission and Odor Control

Beyond energy recovery, the double membrane holder provides a crucial hermetic seal over the digester. This is paramount for fugitive emission control (preventing the release of methane) and for significantly reducing odor emissions, which is a major environmental and community concern for large-scale pig farms. The gas-tight integrity ensures compliance and improves the facility's overall environmental performance.
