Biogas Holder Balloon for an Anaerobic Digestion Tank: Integrated
Gas Storage for Biogas Production
Anaerobic Digestion (AD) tanks are the foundational components of
waste-to-energy facilities, converting organic substrates into
valuable biogas. To maximize the efficiency and safety of this
process, the biogas generated must be immediately and securely
contained. In many modern AD systems, the most efficient solution
is to integrate the gas storage directly with the reactor vessel
itself. This is achieved by placing a flexible, durable membrane
structure directly atop the tank, effectively creating a functional
roof that simultaneously serves as a gas holder. This system is
known as the Biogas Holder Balloon, and it is the premier, proven design for durable, external gas
holding.
Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in containment systems, specializes in
engineering high-performance storage solutions. Our Biogas Holder Balloons are state-of-the-art gas holders specifically engineered to be
placed atop the AD tank. They offer a secure, flexible, and
low-pressure means of capturing and storing the biogas produced by
the digester. By integrating gas storage directly at the source,
our balloons ensure optimal process pressure control, minimize gas
loss, and provide a stable gas supply for downstream energy
utilization.
Product Advantages
Center Enamel’s Biogas Holder Balloons are engineered for the
unique demands of low-pressure gas storage in AD environments. The
design focuses on utilizing high-strength, flexible composite
materials to deliver exceptional performance, safety, and
longevity.
The most critical feature of the biogas holder balloon is its superior gas-tightness and containment. Constructed from specialized, multi-layered PVC-coated polyester
fabric, the membrane material is specifically selected for its
resilience against the corrosive elements found in raw biogas, such
as hydrogen sulfide and moisture. The hermetic seal provided by the
material and its secure anchoring system ensures that virtually no
valuable biogas escapes. This maximization of gas capture is
essential for energy yield and also serves to mitigate fugitive
methane emissions, a key factor in environmental compliance.
Another core advantage is the flexible, low-pressure storage capacity. The balloon's inherent flexibility allows it to expand and
contract dynamically as gas volume changes, effortlessly
accommodating the natural fluctuations in biogas production from
the digester. This dynamic buffering capability prevents dangerous
over- or under-pressure conditions within the digester, protecting
the structural integrity of the entire system. Operating at very
low pressure, the balloon is an inherently safe storage solution, minimizing explosion risk compared to
high-pressure gas storage alternatives, providing a safe operating
environment for plant personnel.
Furthermore, our Biogas Holder Balloons offer exceptional durability and weather resistance. The outer membrane is designed to provide structural integrity
and protection, often maintained under a slight positive air
pressure to shield the inner, gas-holding membrane from the
elements. This dual-membrane structure, or similar reinforced
design, protects against high winds, heavy snow loads, and damaging
ultraviolet (UV) radiation. The materials’ superior resistance
ensures the system maintains its performance and structural
integrity over a long operational life, requiring minimal
maintenance and offering a cost-effective solution built to last in
challenging outdoor environments. The lightweight and modular
nature of the system also ensures rapid and easy installation on various tank types, reducing overall project timelines and
construction complexity.

Product Application Areas
Center Enamel's Biogas Holder Balloons are a crucial component
across a wide spectrum of anaerobic digestion and biogas
utilization projects, ensuring efficient gas management and
recovery.
Biogas Engineering and Energy Recovery: The most prominent application is in dedicated biogas plants that
process agricultural residues, energy crops, and animal manure. The
holder balloons are essential for collecting and storing the gas
before it is fed to combined heat and power (CHP) units or
upgrading equipment.
Livestock Wastewater Treatment: In large-scale pig, dairy, and poultry farms, the balloons are
placed atop the digester tanks to capture the methane produced from
manure treatment. This turns a waste management challenge into an
on-site energy source, allowing farms to become energy-independent
and manage odors effectively.
Food Waste and Industrial Wastewater Treatment: Industries such as food processing, breweries, and distilleries
use these holders to capture biogas generated from high-BOD
wastewater. This dual function of waste treatment and energy
generation significantly reduces operating costs and improves
environmental compliance.
Municipal Wastewater Treatment: In urban sewage treatment plants, biogas balloons serve to contain
the methane generated from sewage sludge digestion, allowing the
plant to use the gas for its own energy needs, thus lowering
municipal expenses.
Global Reach and Proven Excellence: Project Cases
As a premier provider of containment systems, Center Enamel has
established a global footprint with numerous successful projects
across various applications that demand sealed, durable, and
reliable storage, principles directly relevant to high-performance
