Table 5. Electrical Energy per Order (EEO) for the Degradation of Perfluorooctanoic Acid (PFOA) for Different UV-ARP.
technology | EEO (kWh/m3)a | ref |
---|---|---|
UV/sulfite, pH 12.0, 18 W, 600 mL, kobs = 4.4 h–1 (bench) | 15.8 | (79) |
UV/sulfite, pH 11.2, 1320 W, 568 L, kobs = 1.5 h–1 (pilot) | 3.7 | (32) |
UV/indoleacetic acid/micelle, 500 W lamp, 10 mL treated, kobs = 1.7 h–1 (bench) | 67 600 | (28) |
EEO calculated as EEO = 2.303/kobs × power/volume, where kobs (h–1) is the first-order rate constant, power is the lamp power in kW, and volume is the treated volume in m3.
