Chlorine dioxide has been used for water treatment in public sewage treatment plants around the world since 1944.<\/strong> Due to its selective oxidising properties,<\/strong> its use is an alternative that should be considered if the organoleptic quality of the water is to be improved in addition to disinfection.<\/p>In addition, iron and manganese<\/strong> as well as other colouring and flavouring compounds can be removed(1)<\/em>. <\/p>Studies show that it is more effective<\/strong> than chlorine<\/strong> as a disinfectant against waterborne pathogens such as viruses<\/strong>, bacteria and protozoa under all circumstances (2).<\/em><\/p>On the other hand, unlike other products, chlorine dioxide is effective in a very wide<\/strong> pH<\/strong> range<\/strong> (4-10)(3)(5).<\/em> Its oxidising power is better than that of chlorine, chloramine and iodine, and it is much better than ozone in already polluted water due to its effectiveness at low concentrations. In addition, due to its high solubility<\/strong> in water, it can act over a longer period of time, which is a great advantage over ozone, which evaporates immediately and requires constant application over a longer period of time (4).<\/em><\/p>One of the main advantages of using chlorine dioxide is that it reduces the formation of organic by-products<\/strong> harmful to people and the environment, such as trihalomethanes (THMs) and chloramines (4).<\/em><\/p>Chlorine dioxide in sufficient quantities is capable of oxidising phenolic compounds.<\/strong> (7): BPA (bisphenol-A) contamination from plastics causes damage to the body. The only functional group in BPA is two alcohols, which, if oxidised, could render BPA non-toxic. The mechanism of action of BPA has not yet been elucidated, therefore, its effect cannot be attributed to functional groups.<\/em><\/p>In addition, ClO2 does not react with ammonia or primary and secondary amines, which avoids increasing chlorine demand in distribution systems.
