Managed aquifer recharge as a barrier for ozone-based advanced oxidation by-products: BrO3- and H2O2

Managed Aquifer Recharge (MAR) is a technology that relies on soil passage - after pond infiltration - for water treatment. MAR is a proven technology for the removal of pathogenic micro-organisms, turbidity and a selection of specific organic micro-pollutions (OMPs). Nevertheless, removal of the wide variety of OMPs found in surface waters requires additional treatment. The application of O3-based advanced oxidation processes (AOPs) before MAR has been proposed as a smart solution, because previous studies have documented complementary and synergetic benefits for the removal of OMPs. However, the effect of the installation of O3-based AOP as a chemical process on the subsequent MAR as a biological process is not known yet. Especially the behaviour and fate of O3-based AOP by-products and residuals on MAR raise many questions. This thesis focused on the behaviour and fate of BrO3 - as an O3-based AOP by-product and
H2O2 as an AOP residual during MAR.
