Abstract

The invention relates to a process for the treatment of atmospheric cooling waters circulating in a semi-open circuit recirculation loop comprising an atmospheric cooling device (2) equipped with means for the natural or forced convection of atmospheric air, a bleeding device (D) and a make-up water feed, (E), characterized in that carbon dioxide is introduced at at least one point in the said recirculation loop or in the said make-up water feed or in a bypass circuit provided on the said loop or the said feed for the purpose of the said introduction.
