Nowadays the planet is suffering, as a victim of the excessive human consumption. As a result, the resources are diminishing while the population is increasing, and they are badly shared. It is especially the case of the water, rare commodity which is the subject of an outrageous and inconsequential consumption despite the fact that it is an essential component of our society. But luckily since a few years, people seem to become aware of the importance of being sparing with water ressources : they take more and more care about the respect of the environment and they are starting bit by bit to work towards ecology.
The importance of water treatment
Currently only the two percent of the used waters are recycled through the world : it is completely derisory compared to the millions of liters that we consume, particularly knowing that many people worldwide do not still have any access to water in several countries. However, it is important to know that it is absolutely possible to recycle soiled water to reuse them for the daily consumption : indeed there are a lot of water treatment plants in the world, which are responsible for water treatment to make it suitable for consumption. Once treated and purified, it is able again to be used and even drunk.
How to treat used water ?
The wastewater is the subjetc of a specific eight-step treatment. Firstly it is filtered through a sieve to remove the biggest impurities. Then it is degritted and degreased, and it is treated once with chlorine. After that it is aerated to bring it oxygen, then it is sent through a big sedimentation tank to enables the sediments to fall at the bottom. It is treated a second time with chlorine and ozone, and possibly a third time to totally purify it. Click to learn everything about urban and industrial sludge.
