Nowadays people are starting to realize that the water is a rare commodity, and that we have to stop wasting it at any cost: however it is one of the most badly exploited of the planet, on one hand because it is over exploited and on the other hand because it is not recycled. Indeed, only the two percent of wastewater in the word are treated to be reused, while several countries still do not have any access to drinking water. However there is an effective way to purify the water to make it drinkable.
Why it is important to recycle wastewater?
Nowadays we consume in an outrageous way, without worrying about the consequences on the environment or either the future of the planet. However the water resources are not inexhaustible and it is absolutely compulsory to preserve them. Although many people are worried about reusing wastewater, they should know that it is enough to treat it correctly to make it suitable for the daily consumption: indeed once it is purified, it can be used by the industry, the cities and the farmers for example. It even can be injected again in the drinking water circuit, to be daily drunk.
Which method to purify water?
To become again suitable for consumption, the water has to be subjected to a very strict treatment. Firstly, it is filtered through a big sieve to remove the biggest impurities and solid sediments. Then it is subjected to a physicochemical treatment, to remove the potentially noxious chemical compounds. After the water is sent in a big sedimentation tank to enable the suspended impurities to fall at the bottom of the water. Then the water is disinfected with chlorine to eliminate organic matters, and ozone to eliminate any bacteria and pathogen. Finally, the sludge is removed an treated separately.
