Double Membrane Biogas Holder for Agricultural Waste Tank: Captures Residual Gas from Slurry Storage to Maximize Farm Energy Recovery

Double Membrane Biogas Holder for Agricultural Waste Tank: Captures Residual Gas from Slurry Storage to Maximize Farm Energy Recovery

Modern, sustainable agriculture requires the efficient management of large volumes of organic byproducts. The Agricultural Waste Tank, often used for storing liquid manure, slurry, or digestate, remains a significant, yet frequently overlooked, source of energy and a site for fugitive methane emissions. Even after primary anaerobic digestion (AD), or during raw storage, the organic material continues to decompose, generating residual biogas.1 To maximize farm energy recovery and ensure environmental compliance, this residual gas must be captured before it escapes into the atmosphere. This demands a flexible, durable, and easily integrated cover solution.

The Double Membrane Biogas Holder is the optimal technology for this scenario. It is installed directly over the tank to form a robust, air-supported cover that captures residual gas from slurry storage to maximize farm energy recovery. This system provides a gas-tight seal, prevents odorous emissions, and collects a valuable, low-pressure gas buffer that can be utilized for on-site energy needs, effectively turning an emission source into an economic asset.2

Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in advanced containment solutions, specializes in engineering high-performance storage systems.3 Our Double Membrane Biogas Holders are state-of-the-art gas holders designed to integrate seamlessly with agricultural waste tanks, offering superior gas containment, pressure regulation, and long-term durability in demanding farm environments.4

Product Advantages for Residual Gas Capture

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the specific requirements of agricultural waste tanks, maximizing gas recovery and environmental integrity.5

Fugitive Emission Control and Methane Recovery

The primary function when covering a waste tank is environmental protection. The double membrane system provides a crucial hermetic seal, effectively stopping the release of fugitive methane emissions—a potent greenhouse gas—from the slurry. This gas-tight integrity is vital for environmental compliance and significantly contributes to maximizing energy recovery. The captured gas, which would otherwise be lost, is now available as a cost-effective fuel source for heating water, heating digestate, or operating generators.

Resilience to Corrosive Biogas and Waste

Biogas generated from animal waste and slurry is often highly saturated with moisture and contains various corrosive elements. The balloon is constructed from specialized, multi-layered composite fabric, which is selected for its exceptional durability and resistance to corrosive elements.6 This resistance is crucial for the long-term integrity of the gas-tight seal, maximizing the collection of the valuable biogas and minimizing the maintenance needs in this demanding environment.

Durability and Weather Protection

The robust, double-membrane architecture ensures exceptional structural resilience against the farm environment. The outer membrane is air-supported to form a rigid, protective dome that shields the inner gas-holding membrane from external environmental stresses, including strong winds, heavy precipitation, and ultraviolet (UV) radiation.7 This proven protection guarantees a long operational lifespan and low maintenance requirements, which are vital for continuous farm operations.8
