Chlorine is the most common chemical used to treat and sterilize swimming pool water. When chlorine (in the chemical form of calcium hypochlorite) is added to a swimming pool it destroys pathogens and oxidizes materials such as chloramines. When chlorine is added to water a week acid called hypochlorous acid (HOCL) and chloride ions (CL-) are produced. The hypochlorous acid is what gives water the ability to oxidize and sterilize and disinfect the water. CL2 + 2H2O <----> HOCl + CL- + H2O -Equation One The hypochlorous acid then splits into hypochlorite ion (OCL-) and hydrogen ions 2H2O + HOCL <----> H3O+ + OCL- -Equation Two OCL- and HOCL both act on pathogens in the swimming pool water, though HOCL is approximately eight times more effective as the negative charge on OCL- slows down its ability to attack the organism’s cell walls. Hypochlorous acid (HOCL) isn’t stable and it degrades when it is exposed to ultraviolet light, (sunlight) therefore ineffective when it comes to sterilizing pool water. With ultraviolet light, HOCL has a photochemical reaction (photolysis). 2HOC...

    HOCl is a much stronger disinfectant than hypochlorite but their relative distribution depends upon pH. At pH > 4 dissociation of Cl2 is almost complete whereas at pH values greater than 5, HOCl starts dissociating and there is an increase in concentration of OCl-. The effect of pH on chlorination is shown in fig 1.1(a).

    “Recreational water illnesses (RWIs) are caused by germs spread by swallowing, breathing in mists or aerosols of, or having contact with contaminated water in swimming pools, hot tubs, water parks, water play areas, interactive fountains, lakes, rivers, or oceans. RWIs can also be caused by chemicals in the water or chemicals that evaporate from the water and cause indoor air quality problems. RWIs may include a wide variety of infections, including gastrointestinal, skin, ear, respiratory, eye, neurologic and wound infections. Many RWIs (skin, ear, eye, respiratory, neurologic, wound, and other infections) are caused by germs that live naturally in the environment (for example, in water and soil)” (Centers for Disease Control and Prevention).

This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers."

Such wastewater has a bad color and high (or low) pH value, and it needs a strong treatment method.
