Membrane Biogas Dome
Reinforced PVC membranes
Faster to install and more economical
Less maintainance than fixed roof systems
A PVC double membrane biogas dome / roof can be installed on new or refurnished steel and concrete tanks. There are a number of benefits to opting for a double membrane biogas dome over a steel or concrete fixed roof. These include;
- Greater flexibility in terms of size and shape
- Saves the cost of a fixed roof
- Most economical solution to collect and store gas
- Suitable for pressurised applications
Air membrane is manufactured using a single sided PVC coated polyester material which is UV, microbial, abrasion and flame resistant.
Gas membrane is manufacture using a double sided PVC coated polyester material which is UV, microbial, abrasion, flame retardant, H2S and biogas resistant.
The Fan and air control valves fitted to the air membrane are sized and selected to ensure that a constant pressure is maintained at all gas flows within the digester.
A stainless steel post is installed at the centre of the digester to support a netting system which prevents the inner membrane from making contact with the slurry when fully deflated.
Both air and gas membranes are sealed to the top of the tanks using stainless steel clamp plates and fixings.
