If there is an amount of unpackaged water in safe bottles, it can be boiled, and this is the appropriate way to kill pathogens, such as: viruses, bacteria, and parasites, by:
• Filter the water with a clean cloth, paper towel, or leave it for some time for the impurities to settle to the bottom of the pot in case it is cloudy
• Put filtered water in a boiling pot
• Put the water on a source of heat, and leave it to boil for one minute, and if the height is more than 1980 km, the water should be boiled for three minutes
• Leave the water to cool down. To improve the taste of water, you can pour it from one bowl to another and let it cool for several hours, or by adding a pinch of salt to every liter of water.
• Store water in sterile containers with clean lids
In the event that the water cannot be boiled, it can be disinfected using household bleaching materials, containing 6-8.25% sodium hypochlorite without scents, or additional cleaning agents, through:
• Filter the water if it is cloudy
• Get a clean dropper
• Add eight drops of ovary if its concentration is 6%, or six drops of ovary if its concentration is 8.25% per gallon of water, i.e. 3.7 liters, and the quantity is doubled if the water is too cold, cloudy, or colored
• Leave the water for thirty minutes before drinking, provided that the water has a slight smell of chlorine.
• If the water remains cloudy, you must double the amount of ovary, and leave it for another fifteen minutes before use.
• If the chlorine smell is strong, the water is poured from one bowl to another, and left for a few hours before using it.
The salts in seawater or salt water should be removed, and not limited to boiling them only, as drinking water that contains a high percentage of salts may be fatal. Therefore, the water must be distilled, i.e. separating the salts and other mineral deposits from the water, through:
• Place the water in a bowl, so that the water level is just below the edge
• Put the pot in a large bowl over the heat, until the water boils.
• Reducing heat when boiling water, placing a large cap, and then putting ice blocks on top, to make the steam condense while observing a clean container to collect condensed water.
