Methods used for water purification have changed dramatically over the years. As technologies have advanced, newer techniques were developed to purify water. There are several methods one can use to purify water and three are discussed here.
The first method is distillation and this is the first water purification method ever developed. Simply boil the water and collect the water vapor throughout the process. The trouble with this method, however, is that not all contaminants are removed from the water.
The second water purification method is known as activated carbon filtration. With this method, water is passed through the filters, which occasionally may have silver as a component. Activated carbon filtration will remove most contaminants from the water though it is ineffective in removing extremely small contaminants and microbes from the water.
The final method is known as sub micron filtration. Sub micron filtration is one the best methods of water purification. This method utilizes a synthetic or ceramic membrane that is capable of removing cysts, e-coli and other very small contaminants from the water.
During emergency survival situations access to fresh, clean water is an absolute necessity. In order to be properly prepared, have at least three days of fresh bottled water on hand. As a further precaution, be prepared with water purification knowledge. Doing so will help you survive any emergency crisis.
