the goal
The Goal
  • The goal of the “living machine” is to convert murky, dirty water into crystal clear water.
  • This mimics the natural cleansing processes that takes place in wetlands.
  • The concept was created by John Todd.

making a difference
Making A Difference
  • The overall potential of this treatment process is that it removes pollutants in water.
  • Unlike regular treatment plants, it doesn’t use chlorine and filters out metals using natural means.

how it works
How It Works
  • First, sewage goes in an anaerobic settling tank. This is where large particles settle to the bottom of the reactor.
  • It then goes into a biofilter, which is made of bark and humic material. This helps to reduce odors.
  • Next, the sewage moves to aerobic tanks. It contains photosynthetic algae that put oxygen back in the water.

organisms used
Organisms Used
  • Bacteria are also used for producing nitrates. Managers have to add calcium for these types of bacteria to survive.
  • Taller plants are also used to isolate heavy metals from the environment.
  • Fish, snails, and clams are also used in the filtering procedure.

technological obstacles
Technological Obstacles
  • Bacteria have to be kept in specific conditions to use.
  • This includes temperature, food sources, and pressure.
  • In addition to bacteria, all other processes have to be kept in check.
political economic obstacles
Political / Economic Obstacles
  • No political or economical obstacles exist.
  • The cost of living machines actually much less than other waste sanitation processes by millions of dollars.
negative environmental impacts
Negative Environmental Impacts
  • No negative impacts exist as long as the system is designed correctly.
