Free Standing Double Membrane Biogas Storage Tanks For Sewage Water Treatment Plants


Product Description


MONDES's Free Standing Double Membrane Biogas Storage Tanks For Sewage Water Treatment Plants are exclusively manufactured from advanced structural fabrics, which have been engineered to meet the rigorous demands of various environmental conditions. These tanks are designed as membranes that not only provide structural (climatic) stability but also ensure impermeable gas storage, thereby maximizing efficiency and safety in biogas management. The innovative design eliminates the need for metals in the construction process, with the sole exception being the anchorage that connects the membranes to a concrete foundation slab.

This approach minimizes corrosion risks and enhances durability over time.


Our Free Standing Double Membrane Biogas Storage Tanks For Sewage Water Treatment Plants comes equipped with comprehensive instrumentation systems that facilitate precise measurement and control of the entire storage process. These instruments monitor parameters such as pressure, temperature, and gas composition, allowing operators to optimize performance and maintain safety standards effectively.


These versatile biogas storage tanks can be utilized across a wide range of applications. For instance, they are ideal for solid waste processing facilities where organic materials undergo anaerobic digestion to produce biogas. Additionally, they play a crucial role in sewage water treatment plants by capturing methane generated during sludge decomposition processes. Agricultural waste treatment projects benefit significantly from these tanks as well; they enable farmers to convert livestock manure into renewable energy while managing waste efficiently.


Furthermore, our biogas storage solutions cater to both agricultural- and industrial-scale installations. In agricultural settings, these tanks support sustainable farming practices by providing an eco-friendly method for handling organic waste products while generating valuable energy resources. In industrial contexts, they assist companies in meeting regulatory requirements related to emissions reduction by enabling effective capture and utilization of greenhouse gases produced during manufacturing processes.


MONDES’s commitment to innovation ensures that our free-standing double membrane biogas storage tank systems remain at the forefront of technology within this sector—providing reliable solutions tailored specifically for diverse operational needs while promoting sustainability across industries.


Structural Features


Flexible Material

  • The primary structure of the dual-membrane gas tank is constructed from a specialized high-strength polyester fiber film, which exhibits excellent flexibility and tensile strength. During the processes of gas storage and release, it can adaptively deform in response to variations in gas volume, accommodating different operational pressures.
  • In comparison to conventional steel gas tanks, the flexible material utilized in the dual-membrane design imposes lower foundational requirements and demonstrates an ability to accommodate a certain degree of uneven settlement, thereby reducing both installation complexity and associated costs.

Double-layer Membrane Structure


  • This gas tank features a double-layer membrane configuration consisting of an inner membrane for gas storage and an outer membrane that provides protection and structural support.
  • The interstitial air layer between these membranes can be automatically regulated by a blower to maintain the stability of the tank's shape. As the volume of gas within the inner membrane increases, pressure within this air layer correspondingly rises, causing outward expansion of the outer membrane. Conversely, when there is a reduction in stored gas volume, pressure decreases within the air layer leading to contraction of the outer membrane; this dynamic ensures consistent operational stability for the gas tank.

Lightweight Design


  • Thanks to its use of flexible film materials combined with lightweight structural engineering principles, the overall mass of the dual-membrane gas tank remains relatively low. This significantly lessens demands on foundational support structures.
  • Consequently, this design facilitates more efficient installation and relocation processes while concurrently minimizing project costs and timelines.

After-sales Service


Maintenance and Repair: In the event of a malfunction in a dual-membrane biogas tank, customers are encouraged to reach out to the manufacturer's after-sales service team at any time. The after-sales personnel will provide remote guidance for basic troubleshooting and repair procedures tailored to the specific nature of the issue. Should the problem prove more complex, the manufacturer will dispatch technical staff to conduct on-site repairs, ensuring that equipment is restored to normal operation as swiftly as possible.


Parts Supply: The manufacturer guarantees a consistent supply of necessary maintenance parts, all of which are assured to be high-quality and compliant with industry standards. Following the expiration of the warranty period, these parts will be made available to customers at wholesale or cost price, thereby minimizing their maintenance expenses.

Technical Consultation: Customers encountering technical issues or having operational inquiries regarding their dual-membrane gas tanks can consult with the manufacturer's technical support team at any time. The manufacturer commits to delivering professional technical responses and recommendations through various channels including phone calls, emails, and online customer service platforms.


Operational Training: For newly installed dual-membrane gas tanks, manufacturers offer comprehensive training for operators covering correct operational techniques, daily maintenance practices, and safety protocols. This training can take place on-site during installation or may be scheduled at the manufacturer's dedicated training facility based on customer preferences.


System Upgrade: As technological advancements occur, there may arise a need for upgrades within the control systems of dual-membrane gas tanks. The manufacturer will proactively inform customers about such requirements and provide upgrade services aimed at enhancing both performance and stability.
