Features of Dual Membrane Biogas Dome

A PVC double membrane biogas dome can be installed on new or refurbished steel and concrete tanks.

The membrane biogas dome consists of 2no separate pvc membranes; an outer air membrane and an internal gas membrane. The area between the inner and outer membranes is continually pressurised with air using air blowers. The air inflates the outer membrane providing structural rigidity and an adjustable system pressure.

The membrane gas dome is fast to manufacture and install. It is easy to maintain, only requiring occasional visual inspections. The port holes or viewing windows in the outer membrane allow easy viewing of the inner membrane.

• Biogas 100%used:
  the biogas in inner membrane can be completely squeezed out which is hardly to achieve by the traditional one.
• Light Weight:
  It weights only a small percentage than the traditional one. This does great good for transportation & installation,etc. And saving a lot of construction time & material cost.
• No need to maintain for long time:
  For the membrane industry is made of super anti-corrosion material, and can last over 20 years in the biogas environment. Meanwhile, it is well welded by high frequency welding machine, so there is unnecessary to do regular maintain during operation.
• Save Money, Time & Labor:
  due to its small and light features, and membrane gasholder has been well-shaped in the factory, so it will take 1-2 days for installation on site.
• Anti-freezing:
  as there is no water in the inner membrane, there is no need to worry about the frozen problem in the cold area.
• Keep Warm:
  as we know, air is the perfect medium to keep warm, so the air between two-layers membrane could keep the system warmer than the traditional one.
• Artistic:
  the main color of membrane is grey & white, so it can be easily to be matched, meanwhile, the whole structure is designed to be spheroical, and this arise the sensor of beauty.
• Comparatively Safe when Accident Happen:
  biogas is flammable gases, by any chances explosion happened, it would not cause much dangerous split.
• Easily Repair & Movable:
  supposed unforseeable things happened, the maintenance could be easily done on site.
• Fir Protection:
  the membrane material is non-flammable, the fire protection grade reach the Euro-standard B.
