Choose of volume: 

Storage tanks are designed to compensate for fluctuations in production and consumption, for volume changes due to varying temperatures and for consumers’ stagnation; furthermore, storage tanks store gas for later use. With these parameters the optimal dimensioning can be determined. The ideal storage volume varies according to the plant design, the substrate mixture and the plant management.

Gas-specific membrane:

Our  double membrane biogas tank is made of  high-strengthened, high-elastic synthetic engineering membrane and of perfect anti-acid and anti-corrosion ability. The biogas specific membrane had been widely used in foreign energy treatment,  sewage treatment and other industries. This has been tested that the service life is at least 15 years. 

  

Discription:

  Our biogas storage tank consists of outer membrane which forms the outer shape of the tanks, as well as inner membrane and bottom membrane which make up the actual gas space.

   A permanently running support air blower provides air to the space between inner and outer membrane, and thus keeps the gas pressure up at a constant level – irrespective of gas production and gas withdrawal. The pressurized air has two functions. First it keeps the outer membrane in shape to withstand external wind- and snow loads. Second it exerts a constant pressure on the inner membrane and thus pushes gas at constant volume and pressure into the outlet pipe. The gas charge and discharge pipes are cast into the concrete foundations which are usually supplied by the customer. All three membranes are then clamped to the foundation by means of an anchor ring.

  The safety valve prevents the gas holder from over pressure. The pressure is regulated by means of a pressure control valve. The filling levels are measured by means of ultrasonic andwire length measurement systems.
