Water Purification Process
Thermal Phase Change Process - Distillation
The world's largest water purification system is all around us, although we may never really think about it. Look at the clouds, feel the rain and know that this is all part of the Hydorologic Cycle.
This process can best be seen on an island in the middle of the ocean. Take Guam, in the Western Pacific, for example. Guam is surrounded by hundreds of miles of salty sea-water. This sea water cannot be consumed due to its very high levels of toxins (about 35,000 parts per million of dissolved solids). When it rains in Guam the rainwater is zero parts per million of dissolved solids.
How Did This Occur?
It’s due to the remarkable properties of H2O, stated simply:
When the sun beats on the ocean it causes H2O is change to a vapor and evaporate. When H2O in the vapor phase leaves the liquid phase it leaves the contaminants behind. When the conditions are right the clouds release the H2O as rain and, absent air pollution, the rain is pure water.
This 3-step process is called the Hydrological Cycle and it has been operating for time immemorial.
This is a natural process operating according to the laws of physics and it provides water of amazingly high quality in a continuous cycle.
