Can chlorine dioxide be used to disinfect swimming pools?
For swimming pool disinfection the combination of chlorine (Cl2) and chlorine dioxide (ClO2) can be applied. Chlorine dioxide is added to the water. Chlorine is already present in the water as hypochlorous acid (HOCl) and hypochlorite ions (OCl-). Chlorine dioxide breaks down substances, such as phenols. The advantages of chlorine dioxide are that it can be used at low concentrations to disinfect water, that it hardly reacts with organic matter, and that little disinfection byproducts are formed.
How much chlorine dioxide should be dosed?
The amount of disinfectant required needs to be determined first. This amount can be determined by adding disinfectant to the water and measuring the amount that remains after a defined contact time. The amount of chlorine dioxide that is dosed depends upon the contact time, the pH, the temperature and the amount of pollution that is present in the water.
I learned a lot in this search! Thank-you
