Water is an indispensable substance for life. When the amount of water in our body is low, we may experience dehydration. Some of its symptoms are: weakness, heart acceleration and dry skin, leaving the person weak.
Drinking water is the name given to that water that has no odor (odorless); it has no color (colorless) and no taste (tasteless). For consumption, it must have these qualities, and be preferably fresh, or at a pleasant temperature.
Depending on where it is extracted, drinking water can be consumed immediately, without going through any treatment processes. However, if your source or source is not clean and safe, we cannot ingest it., as it can cause intoxication or health problems, such as diarrhea and vomiting, caused by microorganisms.
Considering the importance of water quality to our lives, the ETAs: acronym for "water treatment plants". There, water is collected from rivers and dams, and passes through filters, eliminating solid particles. It is then treated with chemicals, killing microorganisms that can cause disease.
In many homes, the water is already treated. However, as not all water tanks are properly cleaned, it is interesting that it is filtered before being ingested. Other families also prefer to buy bottles of mineral water, so that it can be used for drinking and preparing food.
Unfortunately, not all homes are supplied with treated water. In this situation, it needs to be filtered, either with a clay filter or strainer, clean. Afterwards, it needs to be treated.
There are two ways to do this, with the help of an adult:
- Put on two drops of bleach for every liter of water already filtered;
- Boil the filtered water for fifteen minutes and then shake it so that it doesn't taste unpleasant.
Fulfilling these steps is also important. store water in a clean place. Afterwards, it can be freely ingested, no problem!
In reality, it would be good for all homes to receive treated water, as many people are not familiar with these procedures explained in the text. Therefore, it is very important that government officials take care of the population, providing them with good living conditions.
