In the global transition towards a circular economy, the efficient and safe management of organic waste streams is paramount. Anaerobic digestion (AD) stands as a proven technology for this purpose, transforming waste into renewable biogas and nutrient-rich fertilizer. A vital element in the success of any AD plant is a robust and reliable biogas containment solution. This is where Double Membrane Gas Holders play a crucial role, serving as the heart of modern Biogas Collection Systems. These innovative units are not simply storage vessels; they are intelligent, flexible components that ensure biogas is captured, protected, and supplied consistently for downstream energy use. As a leading China Double Membrane Gas Holders Manufacturer, Shijiazhuang Zhengzhong Technology Co., Ltd.

A Double Membrane Gas Holder is a sophisticated, all-in-one solution that revolutionizes biogas containment. 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 either on top of a tank or on a separate concrete base. This not only simplifies the project structure but also enhances overall performance and safety.
A typical Double Membrane Gas Holders system 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, and remarkable durability against environmental factors:
Inner Membrane: This flexible membrane serves as the primary gas storage chamber. As biogas is continuously produced 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 anaerobic digestion. The membrane gracefully deflates as biogas is drawn off for utilization, ensuring a consistent and uninterrupted gas supply to downstream equipment.
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 is fundamental to modern Biogas Collection Systems. It ensures absolute airtightness, preventing valuable biogas leakage and effectively containing odors. 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 Double Membrane Gas Holders offer a range of significant advantages that make them a superior choice for modern Biogas Collection Systems:
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. 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 Double 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 project scales and types.
