1500m³ Rim Mounted Biogas Holder with PVDF Membrane for Biogas Plants - 20-20,000m³ Capacity Range
The 1500m³ rim-mounted biogas holder with PVDF membrane offers efficient space utilization by mounting directly on tank walls, eliminating the need for separate concrete bases and pressure-retaining tank roofs. This innovative design provides significant investment savings while reducing installation time and streamlining maintenance processes.
Compatible with both concrete and steel tanks, this system requires proper structural analysis to ensure tank integrity. The dual-membrane configuration features gas containment between the inner membrane and tank shell, with the outer membrane permanently air-supported.
Advanced configurations may include central support columns and under-belt systems to support the inner membrane during gas depletion cycles.
