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.
