Dual Membrane Biogas Domes for Fermenter

Brief introduction of dual membrane biogas domes for fermenter
Dual membrane biogas domes are used for biogas storage. It's mounted tightly on the roof of the reactor. The gas holder system has a double membrane structure.

The external cover dome is made of PVC and produced with special additives that are ultraviolet and precipitation resistant. Internal membrane, which is in direct contact with biogas, is made of a special material PVDF. The internal membrane is stretched by the pressure of the produced biogas. Air is pumped between the cover dome and internal membrane so that it provides pressure to the upper side of the membrane and gives a spherical shape to the cover dome.
Biogas pressure inside the dual membrane biogas domes on average is from 200 to 1000 Pa. The biogas dome provides enough for 2-3 hours storage of biogas.

Membranes are designed and cut using machines with numerical program control. Welding is performed using high-frequency current welding. This gives considerable advantages in quality if to be compared with membranes that are handmade and glued or welded by heating elements. The hermetic sealing in biogas dome mounting systems are secured by pilot-operated check valves. For dual membrane biogas domes operation an excessive pressure valve is installed. Acrylic inspection holes and branch pipes are included into the scope of the gas holder supply.
