Description
Veolia’s MemGas: The Ultimate Valorisation from Biogas to Biomethane
The MemGas membrane technology purifies raw biogas into suitable biomethane (>97-99 % methane) to meet the requirements of its final use. However, in order to be transformed into biomethane, a thorough purification of the biogas is necessary.
The MemGas Process
Advantages MemGas
- Safe and robust pre-treatment process for optimal membrane protection and non-stop biogas purification

- Robust and very reliable with an availability rate > 95%
What is biogas?
Biogas is a valuable source of renewable energy. It is produced by anaerobic purification of industrial
wastewater, anaerobic digestion of sewage sludge and other organic waste, and the fermentation of
organic material in covered landfills. Biogas can then be upgraded to electricity, heat or biomethane.
The latter can serve as natural gas substitute being injected into the natural gas grid or serve as a «green» fuel for vehicles (bioCNG or bioLPG).
