Purified Water Purification Is the purification of water by boiling an effective way to kill pathogenic organisms, including viruses, bacteria, parasites, and can improve the taste of the water after being boiled through poured in another bowl, and left static for a few hours, or by adding a little salt per liter of boiling water , And on the other hand there are many water filters that can be used before boiling, when choosing a filter it is preferable to have pore size in it is very small and follow the manufacturer's instructions. It is worth mentioning that the boiling period varies if the water is net or adverse, and the following are some details of each of them: [1] Pure water If the water is pure, purify it by leaving it boiling for 1 minute before extinguishing the fire (at a height of 1981 meters, it is boiled for three minutes), and left until it cools. The boiling water is then stored in a clean water bottle and closed tightly. [1] Water turbidity If the water is inverted, it is filtered through a clean cloth, paper towel or coffee filter, and left to cool. The net water is then separated and boiled and stored in the same way as before. [1] Purified water with chlorine Chlorine is used in water treatment by adding household bleach detergents. Bleaching usually contains 5.25% to 8.25% chlorine. The use of bleaching agents containing perfumes, dyes and other additives should be avoided. Aker before adding chlorine, and then put the water in a clean pot, add the amount of ovarian and mixing well, leaving the mixture for at least 60 minutes before drinking , and the following table shows the amount of chlorine added to the amount of water: [2] Quantity of water Amount of ovaries (chlorine) 1 liter 5 drops For two 10 drops 4 liters One quarter teaspoon 19 liters small spoon 38 liters Two teaspoons Note: Chlorine will not kill all pathogenic organisms that are normally found in water and will not work to remove all chemical contaminants. Purified water with iodine Iodine is used to purify water if it is unable to boil water or if chlorine is not available. Two drops of iodine are added per liter of water. The number of droplets may increase to 10 drops if water is reversed. There are also other chemicals for water purification, Calcium hypochlorite, chlorine tablets, iodine tablets, potassium permanganate, and product guidelines must be followed when using these chemicals.
