Abstract (en)

The present invention concerns the sector of equipment and components for the production of waste treatment plants. More specifically it concerns a membrane gas holder dome (10) with reduced heat loss, adapted to be installed on a heated digester adapted to produce combustible gas, comprising: - a first membrane (1), impermeable to gases, adapted to delimit, at least partially, a storage chamber (C1) of the combustible gas; - a second membrane (2), impermeable to gases, adapted to delimit, at least partially, a pressurization chamber (C2) superimposed on said storage chamber (C1); - inflation means (15, 16, 17, 18) of said pressurization chamber (C2) by means of an auxiliary gas, preferably air; - a layer of composite material, with heat insulating function, interposed between said first membrane (1) and said second membrane (2).
