Removing Water Pollutants
Removing Water Pollutants
Removing water pollutants in water to be used for emergency purposes is not a difficult endeavor. You only need to be familiar with the different types of pollutants in water and then apply the appropriate method to remove those water pollutants. In this post, we will talk about the different types of pollutants that one can easily find in water and then consequently discuss the methods that work in removing these unwanted elements in your drinking water.
Particulate contamination. Perhaps the most common of all the pollutants in water are particulate contaminants like dust and sediment. In water treatment facilities, the particulate contaminant is removed via filters. This is also true for small scale water purification in the home or outdoors when you are in a survival situation. Using any piece of clothing or fabric with sufficiently small pores such as cotton, one can allow the water to pass through leaving behind the sediment and dust. Water that is brown from excessive concentrations of particulates can be purified by repeatedly running it through cloth filters until the water becomes clear and is deemed safe enough for drinking.
Microbial and biological contamination. Water is an excellent vector for certain diseases such as diarrhea because certain microbial contaminants that carry these diseases are particularly attracted to water. When dealing with water in open sources, it is always best to assume that a certain degree of microbial and biological contamination renders the water unfit for drinking.
Removing water pollutants of this nature can be achieved using a variety of methods. The most common is done by heating the water to its boiling point. Most microbial and biological contaminants are killed off by heat. The use of disinfectants like iodine or chlorine tablets is also helpful. One can purchase iodine and chlorine tablets from stores specializing in survival equipment. You can simply add a chlorine or iodine tablet to a liter of water and allow it to stand for about half an hour before drinking it. In the absence of iodine and chlorine tablets, common household bleach can be used in the same manner as long as the concentration is kept low enough to not cause any adverse effects to the drinker.
Chemical contamination. Chemical contamination is one of the hardest forms of contamination to treat. Removing water pollutants of the chemical nature is best achieved by combining the methods already discussed. First, filter the water to remove the larger contaminants, and then boil off the water. Then, use an assembly that catches the vapor and then use cooling media to condense the vapor back into liquid form. This is the only way you can be sure that your effort of removing water pollutants in chemical form from the drinking water is successful.
You can never know what types of situations or disasters you will find yourself in that warrants removing water pollutants from readily available sources of water in order to make it potable. By getting yourself acquainted with the various types of water contaminants, you can then use the appropriate method that is most efficient and effective in purifying the available water into something that is fit for drinking and other purposes.
