Always remember that after filtration, it is desirable to disinfect water by boiling or using special tablets of the type Aquatables.
In the latter case, depending on the brand of tablets, it is sometimes useful to add some herbs to the water, or to prepare tea instead of pure water to hide the “chlorine” taste and smell of other chemical elements.
They often ask the question – why filter the water, if it still needs to be boiled? The answer is simple: boiling kills bacteria, and filtration removes us from mechanical impurities, sand, silt, plants, and other contaminants that make our water turbid and unsuitable for drinking even after boiling.
To begin with, we draw a hole near the reservoir, below the water level in our river or lake. Then it must be emptied several times, scooping out all the water so that it becomes more or less transparent.
Finally, the water coming to the fossa became less muddy. After filling, we will wait a little more so that the mud settles to the bottom.
Then we use easily accessible materials for the construction of our filter: poles for trinog, gravel, sand, coal, grass (instead of cloth, as the last element of filtration). Also, it is appropriate to use herbs that have a disinfecting effect. For these purposes, moss – sphagnum, a natural antiseptic, is also suitable.
Coal we take from the remnants of our night fire.
Lay the layers in a bottle, in this order (from top to bottom):
4. Grass, which detains seepage elements of sand.
5. At will, at the very bottom – moss sphagnum, etc.
Instead of a tangle of herbs, you can use gauze, dense fabric, etc. All that will not let the sand get into the filtered water. In addition, in our case, holes were made in the lid, through which water was drained.
For example, the photos show water before and after filtration.
And what do you use?
