Chlorine dioxide
Until recently, chlorine dioxide could be used only in large-scale water treatment
applications, because it is a volatile gas that must be generated onsite. Several new
chemical methods for generating chlorine dioxide onsite can now be applied in the field
for small quantity water treatment. Advantages of chlorine dioxide are greater
effectiveness than chlorine at equivalent doses and the ability to inactivate
Cryptosporidium oocysts with reasonable doses and contact times.
