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- “Fixed film ecology” has superseded systems based on hydroponics or a fluid medium.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.
