The objectives of this study was to investigate the H2O2 (10 mg/L in the influent) breakthrough profile with UV/H2O2-GAC system(ultraviolet light coupled with hydrogen peroxide-granular activated carbon) under different operating conditions (in the presence or absence of H2O2 during the ageing process for empty bed contact time (EBCT; Empty Bed Contact Time), two types of GAC) and bed volumes of water containing natural organic matter (NOM) treated) at lab-scale column test(RSSCT; Rapid Small Scale Column Test).
RSSCT studies suggested that both H2O2 exposure and exposure to natural organic matter were important factors in GAC ageing, with exposure to oxygen also suspected of being important. A continuously operated RSSCT was showed H2O2 breakthrough in a GAC column. RSSCT studies showed that carbon ageing significantly reduced the performance of H2O2 quenching by the GAC.
