The tank mounted Biodesulf Double Membrane Gas Storage System consists essentially of an outer membrane, an inner membrane and an optional brace system with a center pole.
The actual gas storage function is done by the inner membrane, which in conjunction with the supporting air blower, provides a constant operating pressure. The operating pressure is kept constant via a pressureregulating valve. The outer membrane provides the shape of the biogas storage and absorbs loads from wind and snow. The brace system prevents the inner membrane from being damaged by the agitator at low biogas levels.
An inspection window is integrated in the outer membrane. It allows for easy control of the biogas filling level. The exact filling level measurement is generally done with a wire length measuring system.
The hydraulic over- and under-pressure safety valves ensure that the membrane will not be damaged by too high or too low pressure.
The Top-Mounted Biogas Storage System is mainly used in agricultural and industrial applications.
