Mian content : 1. Inner membrane for biogas storage The inner membrane represents the gas-proof covering of the fermenter. The gas chamber is located between the inner membrane and the soil. The pressure within the support air space spreads to the biogas via the inner membrane. The inner membrane floats between the outer membrane and the brace system in different heights depending on the filling level.   2. Measuring the filling level The position of inner membrane is measured by 5 infared detecors at the outer membrane, this is more safe and it can be changed easily.   These measured values can be transformed into the auto-control system.     3. Brace system In case of excessive evacuation of the gas storage the brace system prevents the inner membrane from sinking down to the soil where it could be damaged by the mixers.    4. Membrane materials Membranes are made of polyester fabrics which are PVC-coated on both sides. Different membrane types are used depending on static requirements, statutory provisions and customer requirements.   Amoco Biogas Project Pictures:
