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- “Fixed film ecology” has superseded systems based on hydroponics or a fluid medium.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:
“Film music should have the same relationship to the film drama that somebody’s piano playing in my living room has to the book I am reading.”
—Igor Stravinsky (1882–1971)
“Goodbye, boys; I’m under arrest. I may have to go to jail. I may not see you for a long time. Keep up the fight! Don’t surrender! Pay no attention to the injunction machine at Parkersburg. The Federal judge is a scab anyhow. While you starve he plays golf. While you serve humanity, he serves injunctions for the money powers.”
—Mother Jones (1830–1930)
“Delight at having understood a very abstract and obscure system leads most people to believe in the truth of what it demonstrates.”
—G.C. (Georg Christoph)
“The process of writing has something infinite about it. Even though it is interrupted each night, it is one single notation.”
—Elias Canetti (b. 1905)
