The simplest desalination filter for salt water can be made in just a few minutes from any suitable plastic bottle and can from beer or other drinks.
The desalination filter for salt water from a plastic bottle and a can, production and procedure for desalination of salt water.
The salt water of the seas and oceans is unsuitable for drinking because of the high content of salts and minerals in it. To remove them from the human body, more water is required than its drunk amount.
So, for example, in one liter of sea or ocean water contains about 30-35 grams of salts, depending on the region. To remove such an amount of salts from the human body, approximately 1.2-1.6 liters of fresh water will be required. That is, the more you drink salt water, the more fresh water will be needed.
Thus, salt water will not only not quench your thirst, but rather, will lead to rapid dehydration of the body. In addition, conventional dehydration is aggravated by the fact that in salty sea water, among other salts, magnesium sulfate is contained. And it causes severe indigestion. Therefore, consuming salt water, you will die even faster than without water.
However, after desalination, salt water from the seas and oceans can be safely drunk. In addition, in emergency situations, salt water can be drunk if diluted with fresh water at least in a ratio of 2: 3.
Design and manufacture of the simplest desalination filter for salt water from a plastic bottle and can.
The proposed desalination filter has the simplest design and uses the heat of the sun for its work. It consists of two parts, a plastic bottle and a can. As a rule, they can now be found in sufficient quantities on almost any wild coast..
To make a desalination filter, you must:
Cut the bottom of an empty cylindrical plastic bottle with a knife or scissors.
Cut the top of a can of beer or other drinks.
The bottom of the plastic bottle must be bent inward. So that a groove is formed with a height of at least 5 cm.
Fill a tin can with salt water. Put it on a hard surface in direct sunlight.
Put on the prepared plastic bottle. Its cover must be tightly screwed.
From the heat, salt water will evaporate. Vapors will condense on the upper inner surface of the plastic bottle, and the salt will remain inside the can. Drops of fresh water, which will collect on the walls of the plastic bottle, flow down and end up in the gutter. When enough drinking water has collected in the gutter of the plastic bottle, you just need to unscrew the cap and drink it.
Features manufacturing and operation of the simplest desalination filter for salt water from a plastic bottle and can.
The larger the volume of the plastic bottle, the better.
The more transparent the walls of the bottle, the better.
When the desalination filter is in operation, the lid of the bottle must be well screwed.
The darker the surface of the can, the better.
The place of contact of the desalination plant with the earth, it is desirable to seal. For example, the same sand.
The desalination filter must always be in the sun..
The performance of the desalination filter shown is extremely low. Depending on the intensity of solar radiation, for 4-6 hours of work during the day, it is able to give you only about 50-70 grams of fresh water. Therefore, it is desirable, if possible, to make and use immediately with a dozen, or even more, of such devices.
In conditions of survival, in emergency and emergency situations, it makes sense to drink not pure desalinated water, but to dilute it with salty sea water. In the ratio of 1.5-1, and even better 2: 1.
It also makes sense to leave such a desalination filter in operation at night. Due to the difference between day and night temperatures, the process of condensation of water droplets on the inner walls of the plastic bottle will continue.
The process of desalination of salt water from a can can be artificially accelerated. For example, carefully placing the entire structure over the heat of the fire. However, it should be borne in mind that the can can become very hot and deform the plastic bottle.
