The main contaminants in swimming pool are released by human including sweat,saliva,scurf,cosmetics and germ etc. For disinfecting pool water, the core task is to eliminate body contaminants. However, out of the less-advanced water treatment facility and technology, coagulant which is mainly aluminium salt in line with algicide which is mainly copper sulfate will be used during the disinfection process. At last, the body contaminants will be successfully removed with chemicals left that will risk people's health.
Why the chemicals left? Too reasons as i researched: Firstly, body contaminants can be merged by coagulant then big-size merged parts will be filtered but some tiny materials still dissolved in water. As time passed by, aluminium salt continuously dissolved that will be absorbed by body skin. Secondly, despite body contaminants, the sourced water needs to be improved by copper sulfate. After all, the copper ion is virulent to people's kidney eventually threatening the whole body health.

The mostly used chemicals recently for swimming pool water disinfection is chlorine. Whereas, chlorine will react with organic matter in water to be trichloromethane and chloroform which are cancerogenic substance public known . These substances will also be absorbed by body skin then stimulate eyes and skin causing serious pinkeye and roseola.
Well, what is the best way for sterilizing swimming pool water? Using ozone technology. Ozone is internationally recognized as environmental green disinfection substance. Secondary pollution will never be generated by ozone. Ozone keeps strong oxidation capacity that can oxidize iron and manganese efficiently and decompose both of the corrosion and tiny substance. The pool water clarity will be greatly improved and the water will be natural blue without copper salt added.
In another blog Why Use Ozone Generator for Pool Water Disinfection ,the detailed ozone application advantages have been described.
