The global challenge of managing agricultural waste, particularly biomass like wheat stalks, presents a significant opportunity for sustainable energy generation. Traditionally, wheat stalks are often burned or left to decompose, leading to air pollution and greenhouse gas emissions. However, through anaerobic digestion, this agricultural residue can be converted into valuable biogas and nutrient-rich fertilizer. A critical component in unlocking the full potential of this "waste-to-energy" conversion is the biogas containment system. The Membrane Gas Holders have emerged as an indispensable technology for this purpose, providing an efficient, safe, and reliable solution for managing the biogas produced from Wheat Stalk Digesters. As a leading China Membrane Gas Holders Manufacturer, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is pioneering the design and production of these systems, enabling farmers and agricultural enterprises worldwide to transform their waste streams into a sustainable energy source.

By seamlessly integrating the functions of a cover and a gas holder, Center Enamel provides a streamlined, cost-effective solution that contributes to a more sustainable and energy-independent future for the agricultural sector.
A Membrane Gas Holder is a sophisticated, all-in-one solution that revolutionizes biogas containment, particularly for the unique demands of agricultural waste streams like wheat stalks. Unlike traditional systems that may use a separate rigid cover and an external gas storage tank, this design combines these two critical functions into a single, cohesive unit installed directly on top of the anaerobic digester. This not only simplifies the project structure but also enhances overall performance and safety.
A typical Membrane Gas Holder consists of a double-membrane structure made from specialized, high-strength, gas-tight membrane material, usually PVC-coated polyester fabric. This material is chosen for its exceptional gas impermeability (especially to methane), superior resistance to corrosive biogas components (common in biomass digestion), and remarkable durability against environmental factors:
Inner Membrane: This flexible membrane serves as the primary gas storage chamber. As biogas is continuously produced from the wheat stalks within the digester, the inner membrane dynamically inflates to accommodate the increasing volume. This adaptive capacity is crucial for managing the variable gas production rates inherent in agricultural operations. The membrane gracefully deflates as biogas is drawn off for utilization, ensuring a consistent and uninterrupted gas supply for farm heating, electricity generation, or other uses.
Outer Membrane: This robust external layer forms a permanently inflated, dome-like shape. It is consistently maintained under a slight positive air pressure, supplied by a low-pressure air blower. The outer membrane acts as a vital protective shield, safeguarding the inner membrane and the stored biogas from adverse weather conditions, including high winds, heavy precipitation, and damaging UV radiation. The controlled air pressure within the inter-membrane space also provides structural stability and ensures the inner membrane can move freely, maintaining the stable pressure needed for consistent biogas delivery.
This dual-membrane design ensures absolute airtightness, preventing valuable biogas leakage and effectively containing the potent odors associated with biomass digestion. The air gap between the membranes also provides significant thermal insulation, helping to maintain stable temperatures within the digester, which is essential for consistent microbial activity and high biogas yields.
Our Membrane Gas Holders offer a range of significant advantages that make them a superior choice for modern Wheat Stalk Digesters:
Exceptional Gas-Tightness and Safety: The double-membrane structure and advanced welding techniques ensure an exceptionally gas-tight system, preventing methane emissions and controlling odors, a critical concern in farming communities. The integrated pressure management features also safeguard the system from over-pressurization or vacuum damage, enhancing overall plant safety.
Cost-Effective and Efficient: By combining the functions of a tank cover and a gasholder, the Membrane Gas Holders solution reduces the need for separate gas storage tanks and complex piping, leading to lower material, construction, and installation costs.
Superior Durability and All-Weather Performance: Made from durable, corrosion-resistant, and UV-stabilized PVC-coated fabric, our holders can withstand harsh weather and the corrosive nature of biogas. This ensures a long service life with minimal maintenance.
Enhanced Thermal Insulation: The insulating air gap helps maintain stable temperatures inside the digester, optimizing microbial activity and leading to higher, more consistent biogas yields, even in colder climates.
Low Maintenance Requirements: Unlike rigid covers that require frequent inspection and corrosion protection, our membrane holders have minimal maintenance needs, reducing long-term operational costs and downtime.
Flexible and Adaptable Design: The modular and lightweight design allows for quick installation and can be custom-tailored to fit a wide range of tank dimensions and biogas production rates, a necessity for diverse farm sizes and waste volumes.
