various specialty chemicals like algaecides and clarifiers are indispensable in preventing and controlling algae growth and improving water clarity, respectively. Cyanuric acid serves to stabilize chlorine in outdoor pools, protecting it from degradation due to sunlight exposure. Salt, used in saltwater pools, undergoes electrolysis to generate chlorine, offering a more sustainable disinfection method. Moreover, chemicals like calcium chloride and metal sequestering agents contribute to preventing corrosion and staining of pool surfaces, ensuring the longevity and aesthetic appeal of pool infrastructure. In conclusion, the judicious use of these chemicals in water treatment processes underscores their indispensable role in safeguarding public health and maintaining water quality standards for both drinking water and recreational swimming environments.
