The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications.

How Important is Water?As we all know‚ water is essential for mankind ’s survival. However‚ people seem to believe that our water supply is endless since there is more water than land on this Earth. Water regenerates and is redistributed through evaporation‚ making it seem endlessly renewable. So why worry?Actually‚ only one percent of the world ’s water has the capability of being used by us. About ninety-seven percent is salty seawater‚ and two percent is frozen in glaciers and polar ice caps.

Water is a vital to all human life‚ but people don’t know how they should limit their use of it‚ how their actions affect the purity of it‚ or how restricted water actually is. They do not know how to take care of water‚ or their environment. They need to realize that water should not be carelessly used for leisure. Also‚ recognize that they pollute their own water supply with chemicals and trash‚ and they do not seem to understand that there is a limited supply of water. Americans do not comprehend

Water is our past. Water is our future. Without it‚ we cannot survive‚ and there are no alternatives. Many people have likened the issue of water scarcity to our current economic struggle over petroleum. Without petroleum‚ we can’t drive our cars‚ and maybe we have to walk to school or work. This is not the case for water‚ as we are not dealing with simple inconveniences (as grandiose as they may be)‚ we are dealing with the issue of sustaining life itself.
