Electro/UV/sulfite process efficiently removed (a-c) various organic compounds and (d) E. coli microbe, together with automatic adjustments of (e) dissolved oxygen and (f) solution pH. Conditions: 1 mM sulfite, 10 mM Na2SO4, 200 mA, UV. 5 μM ibuprofen, salicylic acid, and bisphenol A were used as micropollutants; 106 CFU/mL E. coli cell in exponential-phase was used as model pathogen. 5 mM tert-butanol and ethanol were used for (a-c), and 100 mM tert-butanol and thiourea were used for (d). Solution was neutral before sulfite addition, and it turned alkaline (~ pH 8.6) after sulfite addition. Data in panels (a-c) were fitted with pseudo first-order reaction kinetics.
