Definition - What does Treated Water mean?
Treated water is any type of hydrogen dioxide H2O) that undergoes processing to serve a specific end use. The water treatment process involves either the subtraction of components from the water, the addition of components to the water, or both. There is more than one way to produce treated water. There are also multiple types of treated water. Among other applications, water treatment is used for drinking water.
Corrosionpedia explains Treated Water
Water treatment is necessary for many different applications. Perhaps the most frequently thought of application is drinking water. Treated water for this purpose goes through processes to make it safe for consumption by humans or other animals. Examples of water treatment processes for drinking include desalination, coagulation, sedimentation, filtration and disinfection. Most often, a combination of the processes is used to produce treated drinking water.
Another application where treated water is produced is wastewater recycling. Wastewater is often produced as a byproduct of other industrial processes. Sometimes the wastewater is too hazardous to return back to nature. The wastewater must be treated to that it does not damage the environment.
Water treatment is also performed for industrial wastewater applications to prevent corrosion. As water works its way through some industrial processes it can pick up bacteria and chemicals that will cause corrosion to occur in the water vessel. The water must be treated so that this corrosion does not occur.
