The purpose of this study was to find out whether adding dissolved oxygen to the reaction medium in a continuous stream of pure oxygen or air with different H<sub>2</sub>O<sub>2</sub> dosage strategies could improve the Dorfman mechanism, generating secondary oxidation species that could boost mineralization, and consequently, diminish H<sub>2</sub>O<sub>2</sub> consumption. Experiments confirmed less efficient COD elimination. Additional DO slightly increased H<sub>2</sub>O<sub>2</sub> consumption, as it initiated a series of reactions generating hydroxyl radical scavengers and H<sub>2</sub>O<sub>2</sub> self-decomposition slowing down the reaction. At the same time, the study highlighted that automatic H<sub>2</sub>O<sub>2</sub> dosing based on DO setpoints would be a highly attractive control option, however, more detailed studies on the initial amount of hydrogen peroxide and dosing rates must be undertaken.</p> </div> <p> </p> </p></abstract><publication_date><month>07</month><day>25</day><year>2014</year></publication_date><pages><first_page>553</first_page><last_page>560</last_page></pages><publisher_item><identifier id_type="pii">gnest_01332</identifier></publisher_item><doi_data><doi>10.30955/gnj.001332</doi><timestamp>1714940276</timestamp><resource>https://journal.gnest.org/publication/gnest_01332</resource></doi_data></journal_article></journal></body></doi_batch> </div>
