Amongst the 11 best water purification methods, the simplest method to purify water is to boil it for a good amount of time. High temperatures cause the bacteria and virus to dissipate, removing all impurities from the water. In doing so, chemical additions cease to exist in the water as well. However, the dead micro-organisms and impurities settle at the bottom of the water, and boiling does not help eliminate all the impurities, see here. You must strain the water through a microporous sieve to completely get rid of the impurities. Hence why boiling water is not an effective water purification method.
An alternative to the UV filtration is solar water purification which involves treating water with the ultraviolet radiation of the sun. The process involves filling a transparent container with water, shaking it to activate the oxygen, and leaving it horizontally in the sunlight. This effectively kills bacteria and viruses present in the water, making it safe for consumption. However, these impurities remain in the water making this a poor alternative to a water filter.
Clay Vessel Filtration
Way before people had access to a reverse osmosis water system or UV Purifier, they used clay pots which filtered muddy water, by blocking out the mud and allowing pure, potable water to pass through. This method is still used in some rural regions.
Water is exposed to UV Light that kills microorganisms, thereby preventing them from breeding further. But if not coupled with an RO Filter, UV Radiation alone cannot remove impurities and heavy metals. Therefore, a water filter or water purifier is necessary.
This method is used when water with a certain level of salinity needs to be filtered. This process is helpful for eliminating salt content, but it also removes essential minerals. Desalination is not considered to be as effective as modern water purification methods.
Iodine is a red chemical that is easily available as a tablet or a liquid. It is extremely powerful as it kills bacteria and viruses. However, it adds an unpleasant taste and can be fatal if taken in high doses. Therefore, it should only be used if you don’t have access to a better method of purification like an electric water purifier.
Distillation is a water purification process that involves collecting the condensed water after evaporation, which ensures that water is free of contaminants. However, this isn’t as effective as an RO filter because it is time-consuming and eliminates minerals as well.
This is an older technique used usually during an emergency, wherein a mild bleach with approximately 5% chlorine is added to the water. This mixture works as an oxidant and quickly kills microorganisms, making water ‘safe’ for consumption. However, water companies add this chemical to the water supply in large quantities. A chemical that is a proven carcinogen.
An RO Purifier is the best of the 11 best water purification methods. Reverse Osmosis forces water through a semipermeable membrane and removes 99% of contaminants, making it the purest drinking water. Renewell Water are specialists when it comes to water purification. See one of our systems here.
An electric water purifier is one of the 11 best water purification methods. It is the most trusted form of water purification that can be found in most houses today. A water purifier uses a multi-stage process that involves UV and UF filtration, carbon block, and modern water filtration technology that eliminates a majority of the chemicals and impurities.
Grab a few stones, wash them, and throw them in the coals of a hot fire.
Once the rocks are hot enough, they can be removed with wooden tongs and placed into your water container. If your water doesn’t begin to boil within seconds after dropping the rocks in, then you will have to continue adding hot rocks until it does or start over again.
The best vessels for this strategy are larger, hollowed-out rocks that are capable of holding water.
