MESSAGE:
Dear Seamus,
Would it be necessary to have like the DHS a permanent air supply to this enclosed reactor to strip Methane out of the effluent?
What do you think?
Thanks,
Detlef

maybe the location? : goo.gl/maps/tb0RU...The system consists of two parallel ABR tanks followed by a set of 6 aerated horizontal subsurface flow wetland cells (each one about 4000 m2). Additional treatment is provided by 2 x Bauxite Residue Filters (4000 m2 each) [for disinfection].
There is no reuse of the biogas in this case.
At the Alcoa Technology Centre in Pittsburgh, USA they also have an ABR + aerated wetland system [for their cold climatic condition] for treating the sewage from the facility. ...

- Seeing the very small long section pictures, after the ABR it looks like an aerated horizontal flow Constructed Wetlands ( Actively aerated treatment wetland system , and a down-stream filter with bauxite gravel for final polishing.

- No information found about use of biogas from the ABR.
- Seeing the large picture, probably the municipal wastewater being transported by larger tankers (honey-sucker) to the ABR of wwtp.
The wetland system been engineered since May 2013 by BAUER Resources GmbH: www.bauer.de/en/bre/index.html and ABR by others?
www.alcoa.com/global/en/news/news_detail...0178en&newsYear=2013Alcoa’s Natural Engineered Wastewater Treatment system comprises three steps: (1) an anaerobic treatment tank that removes metals and breaks down and separates organic material in the water; (2) a passive engineered wetland that utilizes vegetation for further treatment of organics and removal of nitrogen; and (3) a cell housing bauxite-based technology that disinfects and polishes the water. The result is water treated to the same or better quality as that of a conventional system.
