What process is used to eliminate harmful contaminants from the water system?

The process used to eliminate harmful contaminants from the water system is System Disinfection. This process involves using chemical agents, such as chlorine, or physical methods, such as ultraviolet light, to kill or deactivate pathogenic microorganisms in water. Disinfection is crucial for ensuring that water is safe for human consumption and use, eliminating risks associated with bacteria, viruses, and other harmful pathogens.

While filtration also plays a significant role in removing particulate matter and some types of contaminants from water, it does not necessarily eliminate microorganisms. Water softening primarily addresses the hardness of water, primarily removing calcium and magnesium ions, and system verification involves checking the performance and integrity of water treatment systems, but does not involve the direct elimination of contaminants. Thus, System Disinfection stands out as the specific process designed explicitly for the elimination of harmful contaminants from the water system.
