Living Machine System Process
- “Fixed film ecology” has superseded systems based on hydroponics or a fluid medium. In fixed film systems the wetland cells are filled with a solid aggregate medium providing extensive surface area for beneficial biofilm (treatment bacteria) growth. Fixed film ecology allows for denser and more diverse micro-ecosystems to form than does a liquid medium. These ecosystems go well beyond bacteria to include a variety of organisms up to and including macro-vegetation.
- Tidal cycles (filling and draining the wetland in accelerated tidal action—12 or more cycles per day) are used to passively bring oxygen into the wetland cells. This action mimics the same type of biological action of natural tidal estuaries. Tidal Flow Wetlands replace the need to blow air into a liquid medium and use gravity to bring atmospheric oxygen into the cell when it is drained.

Famous quotes containing the words living, machine, system and/or process:
“Come Vitus, are we men, or are we children? Of what use are all these melodramatic gestures? You say your soul was killed, and that you have been dead all these years. And what of me? Did we not both die here in Marmaros fifteen years ago? Are we any the less victims of the war than those whose bodies were torn asunder? Are we not both the living dead?”
—Peter Ruric, and Edgar G. Ulmer. Hjalmar Poelzig (Boris Karloff)
“The American people is out to get the kaiser. We are bending every nerve and every energy towards that end; anybody who gets in the way of the great machine the energy and devotion of a hundred million patriots is building towards the stainless purpose of saving civilization from the Huns will be mashed like a fly. I’m surprised that a collegebred man like you hasn’t more sense. Don’t monkey with the buzzsaw.”
—John Dos Passos (1896–1970)
“Books are for the most part willfully and hastily written, as parts of a system to supply a want real or imagined.”
—Henry David Thoreau (1817–1862)
“That which endures is not one or another association of living forms, but the process of which the cosmos is the product, and of which these are among the transitory expressions.”
—Thomas Henry Huxley (1825–95)
