The process of increasing the concentration of hypochlorous acid and hypochlorite ions in swimming pool water, typically measured in parts per million (ppm), is essential for sanitation. An example is adding chlorine tablets or liquid chlorine to achieve the recommended free chlorine level, usually between 1-3 ppm, to effectively eliminate bacteria and algae.
Maintaining appropriate sanitization levels is crucial for bather safety and preventing the spread of waterborne illnesses. Historically, various methods, including copper and silver ionization, were used for disinfection, but chlorination has become the dominant method due to its effectiveness, affordability, and ease of management. Adequate sanitization also extends the lifespan of pool equipment by preventing algae buildup and corrosion.
