Water purification is achieved through processes that involve following steps to reach the maximum possible sanitation. Through different methods, it is sought to eliminate the greatest number of microorganisms and contaminated waste, as well as other substances harmful to human health.

According to WHO, there are nine safe water purification processes, but not all are effective for all hybrid sources. That is, depending on the type of water will know which process is the safest.
In addition to the chlorination, the different types of filtration and boiling, there are water purification methods that are also being used in our country and in other parts of the world, such as reverse osmosis and ultraviolet light.

Reverse osmosis is a purification process that consists of separating, through a semipermeable membrane, the water of the total solids it contains. This process of water purification is not new. It was proposed for the first time in 1953 and since 1980 it is used as an economic and safe process to purify brackish water, that is, sea water; They are not recommended for fresh water.
Another purification process that has been promoted lately is that of ultraviolet light. With a certain wavelength, the purification of water with ultraviolet radiation makes it possible to sterilize bacteria, as well as to decompose other microorganisms harmful to human health. However, this method is not effective in waters containing sediments, and in Venezuela the water that comes through the faucets is not free of them.

In conclusion, it is best to use the well-known purification processes at home. Some specialists recommend purifying the water by filtering it and then boiling it for a minute. Specialized tablets are a reliable option, but due to its scarcity it is best to appeal to filtering and subsequent boiling. In case the water is very contaminated, it is also recommended to add three drops of chlorine for each liter of boiled water.
