If you for some reason have no filter for water purification, it can be cleaned with household products.
There are several ways to get clean drinking water with the help of improvised means.
1. Boiling
This is one of the easiest and most popular methods for purifying water. It’s important to remember that some viruses, bacteria and calcium salts (scale) still remain.
If you take chlorinated water (from the tap), then long boiling in water will arise chloroform – and it’s a carcinogen. It is important to remember that the more you boil the water, the more salts and heavy metals concentrated in it.
2. Silver
We all know that silver has antibacterial properties. For example, all of the bacteria, the silver does not kill, but it can significantly reduce the number of them in the water, preventing their active reproduction. But do not keep silver object in the water more than a day.
3. Purification by silica
This will take the flint stones (the smaller, the better). By the way, you can buy in the pharmacy or on the Internet. Flint has antibacterial properties. It is left in water for a day.
4. Defending
This method helps to significantly reduce water impurities, salts and heavy metals. To defend water is no longer a day, with the lid open. The need to use only 2/3 of the volume, the remaining water is drained at the bottom can gather unwanted impurities.
5. Freezing
Also it is well known that water with impurities freezes for longer (at a lower temperature). But for the freezing of pure water 0 enough temperature. This property of water is the basis of this method of cleaning.
For freezing the desired dishes with a larger area (transparent sudock). Put it in the freezer and from time to time check. When you freeze half the water, put a hole in the ice and drained the water with impurities. The remaining water after defrosting it is possible to drink.
This method kills some types of bacteria and microorganisms. But constantly drinking such water is not necessary: the body is still in moderation desired salt.
