Existing water disinfection processes, such as chlorination, have frequently failed to comply with the Safe Drinking Water Standards because of the formation of disinfectant byproducts (DBP). The formation of undesirable DBPs can be prevented by using ultraviolet light (UV), which can inactivate microorganisms by damaging their DNA. The major disadvantages of UV disinfection are: UV intensity decreases sharply with its passage in water and its decrease is even more significant with high water turbidity; microorganisms attached (hidden) to suspended particles may escape UV irradiation reducing the UV treatment efficiency; and, microbial DNA, once damaged by UV, can be repaired via enzyme repair systems (e.g., photlyase and excision repair) resulting in survival of the microorganisms. In this study, a water disinfection process using UV in conjunction with ultrasound (US) was investigated. A series of experiments were carried out to test the following hypotheses: Hypothesis 1 - UV and US interact synergistically to enhance the disinfection efficiency; Hypothesis 2 - the rates of disinfection by UV, US, and their combination (UVUS) follow the first order or pseudo-first- order kinetics. Experiments were performed in a 4-liter batch reactor equipped with UV and US sources. Water containing Escherichia coli (K-12 strains), as surrogate bacteria, was run through the reactor. Using the total viable count data and mathematical model, the inactivation rate constants, kuv, kus, and kuvus for the UV, US, and UVUS treatments, respectively, were determined. The results suggest that the combined effect of UV and US are likely synergistic, and that the rate of inactivation by UV, US, and UVUS can be explained by the first-order kinetics.
