Double Membrane Biogas Holder for Farm Biogas Digesters Tanks: The Economical, Robust Solution for On-Farm Energy Storage and Usage

Double Membrane Biogas Holder for Farm Biogas Digesters Tanks: The Economical, Robust Solution for On-Farm Energy Storage and Usage

For the agricultural sector, the Farm Biogas Digester Tank is a cornerstone of sustainable operation, converting livestock manure and crop residues into stabilized digestate and valuable biogas. The successful integration of this technology relies on an efficient system for capturing and storing the gas co-product for on-farm energy storage and usage (e.g., heating, electricity generation). Because farm operations require a cost-effective, durable, and low-maintenance solution, traditional, high-pressure, rigid steel storage is often economically unfeasible, particularly for the low-pressure, variable gas output characteristic of farm digestion.

The Double Membrane Biogas Holder is the optimal technology for this environment. It is the economical, robust solution for on-farm energy storage and usage. By acting as the flexible roof over the digester tank, this holder provides a durable, air-supported structure that not only seals the digester contents but also offers a dynamic, low-pressure reservoir. This ensures every cubic meter of gas is captured, pressure fluctuations are safely managed, and the farm achieves greater energy self-sufficiency with minimal capital outlay.

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 with farm digesters, offering superior gas containment, pressure regulation, and long-term durability in challenging agricultural environments.

Product Advantages for the Agricultural Sector

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to maximize the efficiency, safety, and operational longevity of farm biogas digesters. The flexible dome design offers distinct advantages for agricultural applications.

Economical and Simple Implementation

A critical advantage for farm operations is the holder's cost-effectiveness and ease of implementation. Being a lightweight, modular, and prefabricated system, it is far less expensive to transport and install than traditional rigid gas holders. This significantly reduces the civil engineering requirements and on-site labor costs, making it the economical solution of choice for farms aiming for energy independence without excessive initial investment.

Robust Durability Against Farm Environment

The double-membrane architecture provides exceptional resilience against the typical farm environment. The outer membrane is inflated with air to form a structurally rigid, protective dome that shields the inner gas-holding membrane from external environmental stresses, including strong winds, heavy precipitation, and ultraviolet (UV) radiation. This robust protection, combined with the inner material’s resistance to corrosive biogas elements found in manure gas, guarantees long-term durability and low maintenance requirements, which are vital for continuous farm operations.

Flexible Storage and On-Site Supply Stabilization

The system acts as the integrated flexible roof of the digester tank, ensuring maximum gas capture efficiency. The inner membrane dynamically expands and contracts to accommodate the natural fluctuations in biogas production. This acts as a perfect buffer, stabilizing the pressure and supply of gas to the farm’s utilization equipment (e.g., boilers, combined heat and power units), ensuring reliable, continuous energy output for heating and electricity.
