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.

Chemistry Honors Which Type of Water is the Hardest? Hardness is the quality in water that is imparted by the presence of dissolved salts‚ especially calcium and magnesium. Hardness refers to how many mineral particles there are in water. The harder the water is‚ higher the contents of minerals.

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.

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. The global lack of abundance of usable
