Double Membrane Biogas Holder for Pig Farm Wastewater Treatment: Captures and Stores the Biogas Produced by Treating Concentrated Pig Manure

Pig Farm Wastewater Treatment is a critical process for large-scale swine operations, mandated by environmental regulations and driven by the opportunity for resource recovery. The anaerobic digestion (AD) of concentrated pig manure and associated wastewater produces a significant volume of methane-rich biogas. Given the high solids and volume of the feedstock, the resulting biogas flow is substantial and often corrosive. To maximize energy recovery and ensure responsible waste management, a dedicated and strong solution for collecting gas that is generated continuously must be integrated into the treatment system.

The Double Membrane Biogas Holder is the optimal technology for this environment. It captures and stores the biogas produced by treating concentrated pig manure. 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 wastewater treatment plant, offering superior gas containment, pressure regulation, and long-term durability.

Product Advantages for Concentrated Manure Management

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 in wastewater treatment.

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 common with large-scale manure management, which is a major environmental and community concern for pig farms. The gas-tight integrity ensures compliance and improves the facility's overall environmental performance.
