Support Air Blower

This is a specialized device for biogas plants designed to maintain a stable system pressure of approximately 2.5 mbar in the gas storage and throughout the entire gas system.

The operating principle is based on supplying outside air into the space between the gas membrane and the outer shell of the storage. This creates constant system pressure and prevents the formation of an explosive atmosphere in case of possible gas leaks.

ISO container housing solution

The ISO container serves as a secure housing for a flexible gas storage system with an integrated gas membrane. The container housing protects the inner membrane from external influences and allows for safe stacking/elevation on other containers.

Thanks to its modular design, the storage system can be easily expanded. This solution is ideal for biogas plants, gas storage facilities, and other industrial applications, combining safety, flexibility, and efficiency in a practical package.

Integrated level measurement

The gas storage system features a modern measurement system with level sensors installed in the container roof. These sensors accurately and safely determine the fill level of the gas storage.

The collected data is processed in the control and regulation system (PLC) and is used for efficient management of gas consumers. This solution ensures highly efficient gas distribution and enhanced operational safety.

Key features and technical specifications

FlexBio Low-Pressure Gas Storage — Safe and Flexible Biogas Intermediate Storage Solution

The FlexBio Low-Pressure Gas Storage is housed in a robust ISO container and features an integrated gas membrane with a storage capacity of up to 105 m³. An externally mounted support air blower builds up a constant overpressure of 2 to 2.5 mbar in the gas membrane — regulated via an overpressure valve. This pressure is transferred to the gas chamber and simultaneously ensures the system pressure of the biogas plant.

The biogas produced during the anaerobic process is efficiently stored in between and reliably protected by an integrated over- and underpressure safety system. This ensures that the system pressure always remains within the optimal range (maximum 5 mbar overpressure, minimum 1 mbar underpressure) — guaranteeing safe, stable, and flexible plant operation.

Feedback

Urs Imlig

Appenzeller Milchspezialitäten AG

“The wastewater volumes kept increasing. FlexBio was able to provide us with a mobile pilot plant. After successful testing, the plant was quickly installed thanks to its modular design. And everything has been working very well and smoothly together.”

Alfred Oberlindober

CEO & Owner of the Private Brewery Schönram

“We are direct dischargers and, due to growth and the resulting increase in wastewater volumes, we reached the capacity limits of our existing treatment plant. In our search for a solution, we found FlexBio Technologie GmbH to be a competent partner. The cooperation has proven to be highly profitable. We particularly value the modular and flexible design, which can be expanded at any time.”

Josef Blüml

Halsbacher Qualitätsfleisch GmbH

“The compact container solution with drum screen, anaerobic stage, and MBR provides complete wastewater treatment. We are particularly pleased that we can reuse the treated water – this saves operating costs and is a real advantage for our environmental and sustainability goals.”

Ludger Seggering

Popp Feinkost GmbH

“Wastewater is full of energy. We were looking for a solution and found it with FlexBio – generating biogas from wastewater. We are satisfied with the installation of the plant. We are satisfied with the service. And we are satisfied with the results.”

Andreas Mehli

GRegio Energie AG

“FlexBio makes slurry valuable again! With the new farm biogas plant, FlexBio transforms slurry and organic waste into clean energy and high-quality natural fertilizer. In this way, sustainability becomes a real opportunity for agriculture – and the vision of paying for the tractor with slurry comes within reach.”
