Main content:

1.The half sphere shape of the membrane biogas holder which provides for a constant measureable; and repeatable deflation of the inner biogas chamber.

2.A ‘patented’ accurate biogas chamber level sensor and support mechanism that allows the full capacity of the biogas chamber to be used and reliably controls auxiliary equipment.

Simple flat concrete bases required for installation of the membrane biogas holderAbove ground connections for the biogas inlet / outlet pipeworkH2S resistant membrane materialsWelding procedures that allow system pressures up to 50mbar

3.The 3 membrane system offers enhanced safety and environmental benefits:

1)External membrabe for shape and stable pressure

2)Internal membrane for biogas

3)Bottom membrane

Advantages:

Safety - The system completely divides the biogas from the air avoiding any potential explosive atmospheres and sealing of the biogas membrane to the concrete base is not required.Power failure - The system design enables the outer air membrane to remain inflated at all times avoiding possible collapse onto surrounding equipment.Low energy usage – The air blower only runs when gas is being discharged from the biogas holder requiring a fractional kW motor to maintain pressure.
