Key Features of Bolted Steel Biogas Storage Tanks with Double Membrane Roofs

1. Superior Biogas Storage Efficiency

The Bolted Steel Biogas Storage Tank is designed to safely store and manage biogas produced from anaerobic digestion, landfill waste, or organic waste treatment plants. Our tanks are built to handle the unique pressures and requirements of biogas storage, providing a safe and efficient environment for biogas retention.

High Storage Capacity: Our biogas tanks are available in a wide range of sizes, from small-scale biogas storage systems to large industrial applications, with capacities ranging from 100 m³ to 60,000 m³.

Secure Gas Containment: The tank is designed to withstand the pressure created by the gas stored inside, ensuring maximum safety and integrity during both normal operation and emergency scenarios.

2. Double Membrane Roofs for Enhanced Safety and Flexibility

The Double Membrane Roof system is a key feature of our Biogas Storage Tanks, offering increased safety, flexibility, and gas containment. This type of roof is specifically designed to manage the varying pressures created by the storage of biogas.

Two-Layer Design: The Double Membrane Roof consists of two layers—an inner membrane that holds the gas and an outer membrane that provides additional structural support. This design allows for better control of internal pressure and ensures safe storage of biogas.

Pressure Management: The inner membrane is inflated with air to maintain consistent internal pressure, while the outer membrane acts as a protective cover, ensuring that external factors like wind, temperature, and environmental conditions do not interfere with the gas storage process.

Flexible Design: The double membrane roof system is designed to accommodate fluctuations in pressure, ensuring optimal performance even under varying operational conditions.

3. High Durability and Corrosion Resistance

Our Bolted Steel Biogas Storage Tanks are constructed with corrosion-resistant materials and advanced engineering techniques, ensuring that they can withstand the harsh environments often associated with biogas storage.

Glass-Fused to Steel Technology: The glass-fused to steel coating provides a non-porous, smooth surface that is resistant to corrosion from the biogas and the often aggressive chemicals found in anaerobic digestion. This ensures the long-term durability of the tank.

Stainless Steel and Epoxy Coating: For additional protection, the steel components of the tank are coated with epoxy or fusion bonded epoxy, further enhancing corrosion resistance and ensuring the tank’s longevity.

Weather-Resistant: The tank’s steel structure and double membrane roof are designed to withstand extreme weather conditions, including high winds, heavy rains, and temperature fluctuations.

4. Easy Installation and Modular Design

The Bolted Steel Biogas Storage Tank is designed with a modular construction, which allows for easy transportation, quick assembly, and easy expansion as your biogas storage needs grow.

Pre-Engineered Panels: The tank comes with pre-engineered bolted steel panels, which make assembly quick and efficient without the need for welding or specialized equipment.

Scalable and Expandable: The modular nature of the system allows for flexible scalability, meaning the tank can be expanded in capacity without the need for complete replacement. This is ideal for projects that may increase in size over time.

Cost-Effective: The bolted steel design reduces the overall cost of construction and maintenance compared to traditional welded steel tanks, making it a cost-effective solution for biogas storage projects.

5. Low Maintenance and Long Service Life

Our Biogas Storage Tanks with Double Membrane Roofs are designed to require minimal maintenance while delivering long-term, reliable performance.

Minimal Maintenance: The tank’s smooth, glass-lined surface reduces the buildup of residue, while the double membrane roof system minimizes wear and tear caused by external factors.

Long Service Life: With proper installation and maintenance, these tanks are engineered to last for decades, providing a low-cost and sustainable solution for biogas storage over the long term.

Easy to Inspect and Repair: The modular design of the tank makes it easy to inspect, maintain, and repair, ensuring that any issues can be quickly addressed without extensive downtime.

6. Compliance with International Standards

Our Bolted Steel Biogas Storage Tanks are designed and manufactured to meet the highest international standards, ensuring safety, reliability, and quality.

AWWA D103-09: Our tanks comply with the AWWA D103-09 standard for bolted steel tanks, ensuring their structural integrity and suitability for biogas storage.

ISO/EN 28765: Our tanks are also certified to ISO/EN 28765 standards for glass-lined steel tanks, ensuring that they meet rigorous quality and performance requirements for use in biogas plants.

NSF/ANSI 61: For potable water applications, our tanks are certified to NSF/ANSI 61, ensuring that they are safe for contact with drinking water and meet stringent quality standards.
