How Does It Work?

Enviro2000i ™ – NASA Inspired Technology Creates a Solution for the Non-Chemical Treatment of Water as Used in Cooling & Process Water, and for Cooling Tower Systems

In the 1960s and early 1970s, the Johnson Space Center conducted a research program aimed at development of a small, lightweight water purifier that would require minimal power and no astronaut monitoring. This program produced an electrolytic silver ion generator only slightly larger than a cigarette pack and weighing only nine ounces. One or more units, mounted at various locations in the potable water supply and wastewater system of Apollo or future spacecraft, would dispense silver ion concentrations of 100 to 300 parts per billion, sufficient to eliminate bacteria in the water within hours. IWTE used the NASA technology as the basis for our system. The purifiers in the IWTE system are the same silver ions used in the Apollo system to kill bacteria, plus copper ions to kill algae. They produce water that exceeds the Environmental Protection Agency’s standards for drinking water.

How does the IWTE system remove scale?

Very often, water in plumbing systems contains colloid-sized particles. These include alumina, silica, bacteria, and algae. The colloidal particles have a natural surface charge that is relatively weak. As the colloids move through the water, they collide and aggregate. When the aggregate colloids pass through our wave field the surface charges on the colloids are enhanced. Researchers theorize that this effect may be caused by an ordering in the water molecules absorbed on the surface of the colloids. The net result is that the electrical charge provides the necessary molecular agitation for chemical-free scale prevention and removal. In the specific case of bacteria, the results are even more gratifying. Slime-forming bacteria attach to the walls of the equipment and form bio-film. Bio-film is a habitat for bacteria, such as legionella. Our system enhances the surface charge of the slime-forming bacteria as described above, preventing them from attaching to the equipment. In addition to preventing the corrosive deposits, this deprives the other bacteria of the habitat they need to feed and propagate. In just a few days time, most of the bacteria dies. The entire process ensures proper treatment and increased operational efficiency.
