GTI becomes exclusive distributor of VSO gasholders

Geomembrane Technologies Inc. (GTI), Fredericton, New Brunswick, has announced it is now the exclusive distributor of double-membrane gasholders, manufactured by VSO Biogas Technologies, Artigues, France, in the U.S. and Canada. GTI says its cover experts can deliver, install, and commission these gasholders, and provide advice on how to maximize the use of biogas.

According to GTI, double-membrane gasholders reliably capture methane gas, a naturally-occurring component of biogas generated from anaerobic digestion. They safely store and regulate the use of biogas, which can be used in engines and combined heat and power (CHP) units for electricity and heat at wastewater treatment plants, municipalities and farms. Biogas can be also be used in boilers for process heat and steam or, in some cases, sold to a local utility for profit.

Made from flexible composite materials using high-frequency welding, the gasholders consist of an inner membrane that holds the biogas and an outer membrane that protects the inner membrane from the elements and regulates internal pressure. They range in size from 1,800 cubic feet to 180,000 cubic feet and can be either pad mounted for solid structure digesters, or mounted directly on round digester tanks.
