The Bioplan single-membrane gas-tight roof is a proven solution for storing biogas and biomethane in fermentation and post-fermentation tanks. The design ensures complete tightness, stable operating conditions and effective working pressure control. The system is designed individually for a specific location, taking into account snow and wind loads and the required process parameters.
One gas-tight membrane made of PVC-coated polyester fabric
Complete tightness and dimensional stability
Tensioning system with central column or floating solution
Tight edge connections eliminating gas losses
Integration with agitators, manholes and pressure sensors
Why this solution works
Because it is simple, leak-proof and predictable.
One membrane = fewer components = lower risk of failure. Ideal for installations that need to operate reliably for years without complicating the system.
Technical parameters (range)
tank diameters: up to approx. 45 m
operating pressure: standard from –0.5 to +4.5 mbar
membrane material: PVC 900–1300 g/m²
resistance: UV, chemical, weather conditions
