I first remember reading about using water hyacinth in this way
from the early work of John Todd and thr "New Alchemists". John is
currently running a firm the engineers ecosystems for water
treatment called Ocean Arks Intl. He was also the author of an
excellent book on "Living Machines".
Many of the experts in these areas are hanging out on the Mars
Societys life support mailing list. They are working on biological
systems for the Mars Arctic Research station, and future Mars
missions.

And check out www.greenstar.org
The new Alchemists journals as well as a facinating library of
appropriate tech books is at:

This last is a fascinating resource, soon to be an addition to my
library.
