Finding water shouldn’t be a big problem: rivers, lakes, puddles. You can even dig a small hole and water will collect in it after a while. Even if you boil it, you cannot drink such water. Not only small grains of sand, but most importantly dangerous chemicals and chemicals cannot get caught in them.
Therefore, the best way to purify water is to use a homemade filter.
What do you need to make a filter?
- - plastic bottle.
- - pebbles.
- - sand.
- - a piece of cloth or gauze bandage.
- - Charcoal.
Cut off the bottom of a plastic bottle. Let's turn the bottle over and start filling. First, put a piece of fabric and sprinkle with pebbles. Then add a layer of sand. We put the fabric, crushed charcoal and the fabric again. It turned out to be a kind of tablet.And then, in reverse order, sand and pebbles. The water purification filter is ready.
A cloth or gauze bandage is used to ensure that all filter materials do not mix.
Pebbles and sand are the main filters for small particles. But charcoal retains most of the chemicals from the water. You can use charcoal from your fire.
This filter does not remove viruses and bacteria from the water, so you must boil the water after filtering.
Boil the water for at least 1 minute before drinking it.
If you put some spruce needles in boiling water, you will get delicious tea.
