Double Membrane Gas Holder
The double membrane biogas holder is a biogas holder that is covered with two separate membranes which are blown up by air. The double membranes are always 100% frequency welded, this means the quality of the welding is state of the art. This type of biogas holder is available up to a diameter of 40 meter. There are 3 critical components to keep a stable pressure between the membranes: blowers, air supply system and air relief system.
The blowers make sure there is always enough air blown between the two membranes. For further stabilization of the air pressure, the air supply system and air relief system are always installed.
For the storage of biogas, double membrane gas storage can be installed on both in-situ concrete, precast, or suitable steel tanks. The external weather protection membrane serves to protect the internal gas membrane from the effects of the weather. The gas storage membrane is flexible and varies according to the amount of gas produced. The shape and color of these gas storage covers can be customized according to the requirement and customer's request.
