is well described and can be used on both large and small scale. Chlorine dioxide and
ozone have not been detected in finished water treated with the MIOX mixed-oxidant
solutions, using classical analytical methods. This is likely due to rapid transformation of
the generated oxidant constituents to other forms of oxidants. However, the resulting
solution has greater disinfectant ability than a simple solution of sodium hypochlorite and
has even been demonstrated to inactivate Cryptosporidium, suggesting that chlorine
dioxide is among the chemical generated.{Venczel, 1997 #302} Additional testing is
available on the Miox website.
