Heating
One of the first and most well-known ways of purifying water, or anything else that you’™re going to drink such as milk or juice, is to heat it. There are 2 primary ways to kill bacteria and other impurities in your water so that you can drink it safely.
Distillation
This method uses a ton of fuel but produces extremely pure water. It requires boiling the water in an enclosed container and using a hose or other transportation device to allow the steam to escape, convert back to water, and collect in a clean container. Distillation is highly effective but also one of the more complicated ways of purifying water.
Boiling
This is the surest way to sanitize your water but it may not be realistic if your water but it may not be realistic if your energy sources are limited. If you opt to boil, it takes anywhere from 3-12 minutes depending upon your elevation to kill pathogens and you’™re going to lose part of the water to condensation. For most elevations, 3-5 minutes will suffice but the higher you are, the longer you need to boil it because water boils at a lower temperature at higher elevations. If you choose to boil your water, do so when you’™re cooking or doing other things that require fuel in order to save as much as possible. Again, this is one of the easiest ways of purifying water as long as you have a heating source.
Pasteurizing
Heating your water to 160 degrees for a minimum of 6 minutes will kill pathogens and parasites in water. This uses less fuel than boiling or can even be performed using solar heating devices that you can make at home in a pinch.
Chemical Treatment
Treating your water with chemicals that kill bacteria, viruses, parasites and other impurities is probably the best way to ensure that it’™s safe to drink. The downfall to using chemicals is that you can often taste them in the water. You also need to know how much to use because if you use too little, it won’™t purify the water but if you use too much, it can make you ill. Unless otherwise stated, you should let your water sit for at least 30 minutes in order to give the chemical time to work.
