W. J. Masschelein.

Ozone is now used since one century in drinking water treatment in
Europe. First for bacterial disinfection, followed by taste and
odor control, removal of iron manganese. An irreversible break-
through came in the sixties when was shown that ozone, if properly
applied inactivates enteroviruses which were a problem at that
time. Later came the use of ozone as a factor able to promote
biodegradability of dissolved organic substance, able to cope with
parasites and alone or with synergic procedures with very
refractory compounds like chlorinated pesticides. Parallel to this
evolution of applications the technologies for generating and
contacting ozone to water were constantly adapted. This
contribution will focus on ozonation of drinking water as a public
