Living Machines, Constructed Wetlands and Sustainable Water Resources

Thesis: Conventional waste treatment plants, Living Machines and constructed wetlands can all be used for water purification, but only living machines and constructed wetlands will provide the human race with a sustainable future.

Introduction Our liquid planet glows like a soft blue sapphire in the hard edged darkness of space. There is nothing else like it in the solar system. It is because of water (Miller 311).
- John Todd

Water is the most important resource on the planet. Absolutely no life could exist with out the presence of water. Humans use water to cook, clean, bathe and drink. However it seems that humans as a race have extremely little

Design and Funciton of Treatment Systems

Conventional Sewage Treatment.

Conventional Sewage Treatment plants are the most common system for wastewater treatment in the United States. These systems are found in all urban communities but only in a few rural communities. This complex system is responsible for processing of the waste of the majority of the people in the United States yet few of them understand the scientific principles involved with treatment. In addition many people are even unaware of where their wastewater goes after it has been flushed down the toilet or disappear through the bath tub drain. I will attempt to describe the biological, chemical and physical process involved with the treatment of wastewater through the use of conventional sewage treatment.

The first step involved with wastewater treatment is the transport of the wastes from houses and industry to the treatment plant. This is done through a complex matrix of pipes and lift stations. All sewage goes to the treatment plant using the laws of gravity. Since the flow of gravity requires the sewage to head continually
