The quality of drinking water is a concern wherever you go. There is nothing wrong with drinking tap water. Nonetheless, the bottled water industry has been growing continuously. When it comes to health and safety concerns, consumers can be easily swayed by media and advertising. Even if tap water was 100% clean or even safer than bottled water, people have gotten used to drinking from the bottle.
One of the concerns about tap water is the possibility of contamination. This stems from the large open reservoirs used by water utilities. People can believe whatever they want about the water quality, but if they can see that it is a giant pool of water exposed to the elements, then they can think that contamination really is possible.
Filtration is among the processes that water goes through. This traps solids of different sizes and allows only pure water to go through to the next stage. Large volumes of water are drawn into a tank with various porous filters. The last stage is the filter underdrain.
To ensure that the water is safe, chlorine is used to treat it and keep it safe from bacteria. The amount of chlorine is less than that used in swimming pools. At some point in the process, fluorine is also added. The first major step in cleaning water is aeration. It releases the carbon dioxide in water using a surface water agitator, as well as a fountain or a spray-like device. It also involves the introduction of air underwater.
At every step, the water quality is checked for compliance with safety standards. This ensures that the water is clean and safe for household use or human consumption.
