The Flexfermenter double membraned combined biogas digester and gas store
Combining the best features of the Wiefferink Air Blown Cover and the Wiefferink Combibag to create a second generation low capital cost high quality primary or secondary anaerobic digester to make return on investment and payback periods more attractive in the world where RHI and Feed In Tariffs are at a non sustaining low for traditional biogas plants.
Flexible gas storage, for both temporary and long-term biogas storage.
The gas buffer has been developed for the storage of various gas types. A gas buffer also enables the conditioning and mixing of the gas.
The use of double membrane technology ensures a ﬂexible gas storage volume. Our wide range of gas buffers provides for an efﬁcient construction for the most diverse storage criteria and project objectives.
Environmentally friendly flexible digester, a single skinned combined biogas substrate and gas capture storage system, which can also be used as a manure and digestate endstore for ammonia and methane capture.
The Combibag is a flexible storage for 1,000m3 to 7,500m3 of substrate, manure and digestate, which captures the gases released during the digestion processes.
They can be installed as a primary or secondary anaerobic digester, of even as a tertiary covered digestate lagoon to capture those last tails of gas production.
