They are made with biogas resistant polyester reinforced PVC membranes seam welded by high frequency electronic machines. The air discharge is made with specially designed mechanic valves, while the biogas safety system (necessary in case of over-pressurization) works with liquid fuse safety valves. An electronic sensor senses the level during the filling of the gasholder, and transmits the information to the biogas users. The mechanical anchoring system is made directly on top of the tank wall and gas tightness can be made hydraulically with a weighed submerged membrane or mechanically with special flanges and gaskets. The CUPOLA M3 system is resistant to strong winds, rain, and snow load.

GASHOLDER DOME REPLACEMENT

The CUPOLA M3 domes are used to replace old steel gasholder domes, existing in present waste water treatment plants. Storage volumes can be maintained or increased and installation takes approximately one week to complete, while reducing replacement and maintenance costs.
