Advanced oxidation processes for disinfection treatment of cooling waters

This laboratory study demonstrated the effectiveness of UV-H2O2 on the disinfection of water contaminated with microorganisms and organic matter. It was shown that UV-H2O2 has a higher efficiency than UV or hydrogen peroxide treatments applied alone. Performances were evaluated via microbiological a...

Description
Summary:This laboratory study demonstrated the effectiveness of UV-H2O2 on the disinfection of water contaminated with microorganisms and organic matter. It was shown that UV-H2O2 has a higher efficiency than UV or hydrogen peroxide treatments applied alone. Performances were evaluated via microbiological and chemical parameters analyzed on both, water and biofilms (ATP, culturable and total bacteria, DOC and TOC). The optimization phases of the treatment confirmed a bacterial adaptation to H2O2 when applied alone. This adaptation was not observed in the case of UV-H2O2.
