Hello Everyone
As a contribution to this open discussion, I like to share with you
information on my visits to greenhouses that do phytoremediation of
wastewaters. Note: unlike Paul Adler's set-up, these sites do not produce
any market products. They are basically wastewater treatment systems done
in greenhouses, with a phyto- sub-system and do not recycle water for total
re-use.

(1) Ecological Center at Stensund, Sweden. This site treats 5 m3 of raw
sewage per day in a greenhouse with the sub-systems for anaerobic
digestion, activated sludge aeration, aquatic plants, fish tank and
wetland. Detailed research data is available at

(2) Bodyshop at Arundal, UK. This is uses the Living technologies system
with aeration and plants. My impression is that the use of plants in
nutrient absorption has not been fully realised at this site. Treated water
is sent to a municipal wastewater treatment plant for further treatment.
The Site however has land and ponds that can be used for further treatment
using wetlands.

(3) The Department of Biotechnology, Royal Institute of Technology,
Stockholm is planning to use the Living Technologies approach in project
with a greenhouse corridor to a building. Ms. Karin Larsdotter who is a
member of this discussion can tell you more about the project.
