There are several ways to purify water. Nowadays, here are some tips to help you take care of your health and the health of your children. Recommendations from the Lviv Regional Center for Disease Control and Prevention of the Ministry of Health.
The first and most popular way to filter water is by boiling. Of course, with increasing temperature, most bacteria and viruses die, but for the desired result, the procedure should take at least 5-10 minutes.
The second, and in fact the opposite way, is freezing. Here, another property of water is taken as a basis – the desire to build an ideal crystal lattice in the transition to a solid state. To use this feature of water is quite simple: pour water into a saucepan, but not to the top and put in the freezer on a wooden or cardboard stand. After a certain period of time (approximately several hours, depending on the volume and capacity of the freezer), when about half of the water turns into a solid, break the ice on top and pour out the “dirty residue”. It is desirable to drink thawed water within 10 hours, otherwise it loses its structured useful properties.
The third way is to adsorb from the water some organic compounds, oxidants, odors and tastes can ordinary activated carbon in tablets. It is better to grind it (to increase the active area) and wrap it in gauze or even cotton wool so that black dust does not seep into the purified water. It is better to leave the “bag” immersed in water for the whole night for the best effect.
