Nowadays people are more and more respectful of the environment: they are starting to realize that the resources of the planet are exhaustible, and that we have to preserve them. That is why the recycling is becoming more and more popular in the developed countries. However, many people still are worried about recycling the used water. But it is important to know that currently only the two percent of the soiled water worldwide is recycled to be reuse, which is too little compared to the average daily consumption, and especially when we know that a lot of populations in the poorest countries still have no access to drinking water.
Water in the United Kingdgom: the problem
The United Kingdom has been climate skeptic for a long time: indeed, the country kept developing its industrialization without worrying about the global warming or any other negative impact of this excessive human activity on the environment. But since a few years, the authorities seem to become more and more aware of the importance of adopt a more sustainable way of consumption to preserve the natural resources. Regarding the wastewater treament, some efforts still have to be done, but things are changing bit by bit: indeed, numerous water treatment plants are born these last years.
How to fix it
Once the soiled water is treated in a water treatment plant, it is perfectly clean and ready to be consumed again. To be suitable for the daily consumption, it is the subject of a rigorous treatment: firstly the used water is filtered with a sieve to eliminate the biggest particles, and cleared from fatty substances and sand. Then it is treated with chlorine to remove the germs, and aerated with oxygen to ease the next step. After the water is sent into a big sedimentation tank to allow the thinest suspended particles to fall at the bottom. The last step consists in treating the water with chlorine and ozone to totally purify it.
