The question of whether water purification is necessary in a swampy area or not is not even discussed. There can be a lot of water in a swampy area, but almost certainly there are many harmful parasites and bacteria in it..
Filtration of water in marshy areas, manufacturing a simple filter for water purification from a plastic bottle.
Swamp fever is a general term used for malaria, leptospirosis and mumps, the Everglades virus, also known as Venezuelan equine encephalomyelitis, and cholera. These are just some of the diseases that can be obtained with water quenched. These diseases can lead to very serious physical and sometimes neurological consequences..
Although your NAZ kit must have a kit for filtering water in a swampy area, and a stove to clean it by boiling, in an extreme case, you can resort to an improvised filtration system. Having made it from such materials at hand:
Plastic bottle. They often swim in swamps located not too far from cities.
Charcoal and small stones found along the coastline.
The most important and indispensable layer in this makeshift filtration system is charcoal. It is well known for its ability to absorb a wide range of toxic substances. In its “activated” form, that is, when it is processed so that it can absorb such substances as efficiently as possible, charcoal is the main ingredient in most filtration systems sold, and is also used in the treatment of a number of painful conditions – from flatulence to poisoning.
To make charcoal yourself, light a bonfire on the shore. Let it burn until all the firewood has turned into coal. Fuel briquettes for barbecue, bought in stores, are treated with chemicals and therefore are not suitable as a filter layer.
Self-production of a simple filter from a plastic bottle for filtering water in marshy areas.
Arrange layers in your filter system so that the largest particles are in the widest part of the bottle and trap large debris. The smallest are in her neck. When you spill water through such a filtration system, the droplets appearing below should form slowly. If the outflow of water is stable enough, it means your filtration system is too porous.
Collect items necessary for filtering for water in a swampy area.
Cut the bottom of the plastic bottle with a sharp knife or scissors.
Place layers of filter media in the bottle in the sequence shown in the figure..
Pour dirty water into the top of the filter.
Suitable for drinking water will drop out from the bottom of the filter with drops.
Of course, the safest way to clean and disinfect water in a marshland is to boil it. Therefore, resort to the above method of filtering water in a marshland only if it is not possible to boil it. But the good thing is that at least in a swampy area you will never die of thirst.
