Nancy Jack Todd was a guest at the Sustainability Institute this fall,
and brought slides all the way back to the '70's about OceanArks' work.
What you see on the homepage is a lagoon with waterplants suspended and
floating on the surface using a grid. You might use something like
chickenwire to plug the plants thru. She related that they just began
experimenting with different plants and acquatic organisms and replacing
them until they found what worked. Sequences of aeration, turbulence,
settling and sunlight are all valuable degradation techniques if you can
incorporate them. I don't know about the salt... controlling it thru
dilution? So, the more disproportionate the volume to the area you can
integrate, the more treatment activity you'll want. Waterfalls! River
cane, bamboo, cattails! Courseworks and canals! What a great project.
