How to extract fresh water? How do I get fresh water? Method .

Distillation is relatively pure, but it is cumbersome and costly. The general method in industry is to use membrane separation technology.

In the absence of equipment, it is necessary to boil seawater for distillation water.

In addition to well water, rainwater, snow-melted water, freshwater lakes.

and dew, and sea water (desalination).

Dew formation principle: At noon, the weather is hot, and trees are evaporated into water vapor by the sun.

At night, when the water vapor hits a cold object, it turns into water droplets, that is, dew.

Seawater desalination method: 1Distillation (principle: evaporating water, leaving salt, and then condensing water vapor into liquid fresh water).

2.Freezing method: Freeze the sea water into ice, and the salt will not be frozen, and then melt the frozen ice, which is fresh water.

3.Reverse osmosis method (the principle is very complicated, I don't understand the principle yet, you can search, you can search!) ）

There are many methods, one is to collect rainwater, two is distilled water, three is spring water, four is groundwater, five is river water, six is desalination, seven is chemically synthesized hydrogen combustion to produce carbon dioxide and water, eight biological collection, such as a small amount of water the next day from plant leaves wrapped in plastic bags, and so on.

1.Fresh water is mined underground.

2.Rivers. Lakes with fresh water.

3.Glacial freshwater.

4.Desalination.

5.Distillation.

It makes sense to write like a survival manual, and the instructions on the freshwater distillation device are actually very detailed, so you just need to follow it when the time comes, and you don't have to study it hard.

In case of distress at sea, you can get fresh water in this way without having to use a distillation instrument:

Take a container and fill it with seawater and light it to heat it. When the water is boiling, spread a large plastic film on top of the water, if not, you can take a raincoat, a plastic bag instead. Such water vapor.

Condensation on it forms a lot of small water droplets. At this point, you just need to bend the plastic film and collect its droplets and put them in a container. Salt doesn't evaporate, so all you collect is fresh water! I've tried this method before, and it's been successful, so you can try it.

Actually, there are other ways. The big fish caught have fresh water in their spines and eyes, and this water is drinkable. If God gives you a heavy rain, then just use plastic film to collect it!
