By the time you finish reading this, you’ll know more about the water purification process. It may contain numerous steps that seem very complex and difficult to understand. But, the easiest way to explain it is to break it down into four major steps. Those four steps are the removal of living organisms, the removal of chemicals and heavy metals, balancing the mineral content, and balancing the pH level.
Living organisms may include protozoa, such as giardia and cryptosporidium, bacteria, such as E. coli, viruses, such as the corona viruses, algae and other plant life. The water cleanup process that covers this step is called “disinfection.” In most cases, several different chemicals and UV lights are used at the facility level to complete this process.
In order to fully explain how water is purified, it is important to note that except for algae, the living organisms mentioned above cause a group of diseases called “waterborne illnesses.” Chemical disinfection through the use of chlorine began in the 1900s to prevent outbreaks of these diseases, which include cholera and typhus.
Today, most cases of waterborne illness are caused by either giardia or cryptosporidium. The first usually occurs when drinking from a mountain stream or other source that has not gone through a water filtration process.
The second usually occurs from cyst contamination that cannot be dealt with through chemical contamination. Their removal requires a special purification process for the “point of use” or in simpler terms, the kitchen tap. 88% of all public sources are contaminated with cysts.
The next step in this attempt to explain purification of water is the removal of chemicals and heavy metals. Lead, for example, is a toxic heavy metal. It is naturally present in some groundwater, so the public water treatment process includes steps, such as reverse osmosis, to remove it.
That, however, does not remove chemical contaminants, so carbon beds and sometimes other chemicals are used to trap them. No public water treatment can guarantee the removal of 100% of all chemicals. Lead can only be removed from the source and has recently been found in homes because of aging lead pipes and solder joints Tratamiento de gases.
It is important to mention that point of use purification is necessary to insure that all chemicals, both those used by the facilities and those that they cannot remove, and heavy metals are removed before drinking. In other words, you need a kitchen unit in order to be safe.
Facilities attempt to balance mineral content and pH levels, but their processes are only so effective. Remember water has to run through miles and miles of pipes before it reaches your home. So the mineral content can change and the water can become more acidic or more alkaline along the way. An ion exchange step in a household water purification process is the best choice for this purpose.
