According to our client´s needs, WES offers different types of gasholders designs for the biogas storage on flagstone, concrete tank or metal structure. The gasholders are composed of a single or double membrane which balances the fluctuations of production and consumption with a flexible storage system. Air is injected between the two membranes, maintaining a constant pressure on the membrane containing the biogas; then sending a constant volume of gas to the network.

WES performed several repair and maintenance projects of gasholders in Chile, including a 5,000 m3 capacity gasholder in the Farfana waste water treatment plant, which belongs to Grupo Aguas SA
