What this point illustrates is the importance of water to every living being and, despite its abundance on the planet, much of it is contained as sea water; which means you can’t drink it as it is.
When Is Water Pure?
You are probably familiar with the water cycle; evaporation causes clouds to amass in the sky as the water collects in the atmosphere. It then returns to earth in the form of rain before finding its way back to the oceans.
When it evaporates, water is pure, and the chemicals and minerals that are merged with it will be left behind. Assuming the atmosphere is not polluted this means that the rain falling back to earth is also pure.
However, it doesn’t make it from there straight to your tap. As it makes its way into reservoirs and lakes it travels through stone and soil. In the process it will pick up minerals, debris, and bacteria.
This is why it needs to go through a treatment works before it can be sent to your home.
Why You Need To Have A Water Purifier
The problem is that despite being treated with various chemicals and passed through filters, the water can pick up more debris and bacteria as it travels through the thousands of miles of pipes. The water coming out of your tap may be no cleaner than the water arriving at the reservoir!
You need to learn how to properly filter your water to ensure it is pure. There are several options open to you:
Water purification can be successfully completed through the use of a filter system. This can be fitted into your mains water supply.
You can choose to have a whole house filtration system which will be relatively expensive. Or, you can choose to have the water filter device fitted to a branch of your water supply. It will feed a specific tap allowing you access to properly filtered water at home whenever you want it.
The best systems will use a carbon filter as this is extremely effective at removing bacteria and debris.
As mentioned, when water evaporates it is effectively pure. You can boil it and have a piece of clear plastic above the boiling kettle or saucepan. As the steam hits the plastic it will cool and condense; this can then be directed towards another container to give you clean water.
Of course, this is not a very practical solution!
Table Top Filter
You can purchase a jug with a built-in filter, the filter works on the same basis as the inline filter described above.
This will remove all contaminants but is a slow process, especially if you use a whole jug in one sitting and need more.
This is a great introduction to filtration but not a practical long-term one.
You can buy purification tablets which you add into your water, which will kill the bacteria although it may leave an aftertaste.
The best option is the inline filter, but you may prefer to start with one of the other systems and work your way up!
