Water and chlorine

The importance of drinking Pure Water

The quality of the water decreases as the demographic pressures and the misuses of fresh-water resources increase. During the last decades, for example, there has been a significant growth in the generation of sewage wastes which, by the end of the millennium, was of 2.300 km3 per year due to the increased number of the world population. As most of the sewage liquids are poured without any treatment, polluted waters today represent a high percentage of the total water available for municipal (water supply network), industrial and agricultural use. And, since it is necessary between 8 and 10 m3 of water to dilute 1 polluted m3, in many areas of the world just won’t be enough water to treat pollution.

This constant degradation of the potable water, as much as chemical as bacteriological, increased by the geometric advance during the last decades of the 20th century, has dramatically reduced the water availability.

The use of chlorine by companies in charge of the supply of potable water is usual facing these difficulties. The chlorine generates several results that damage the organisms.

Facing this situation, it is extremely important that the water you drink be purified to ensure its quality, and thus, you avoid the risk of water transmitted diseases (cholera, typhoid fever and salmonella, among others) or of drinking pollutants or sediments that shouldn’t be consumed.

Even though the importance that drinking enough water every day to cover your organism needs, to have pure water is not as simple as it looks like. Pollution has been altering the supply sources during the last decades.

The solution for this contrast between the need to drink water, on one side, and the increasing difficulties to purify it, on the other side, is one of the main challenges of the mankind in the immediate future.
