The effect of the sequential application of ozone followed by monochloramine on enteric viruses
was investigated using MS2 phage as a surrogate. All experiments were performed in 0.01 M
phosphate buffer solution at pH 7.0¿¿¿¿0.1. The inactivation of MS2 phage exposed to
monochloramine alone at a concentration of about 21 mg/L as Cl<sub>2</sub> was found to follow first-order
Chick-Watson kinetics with rate constant k = 2.24*10<sup>-3</sup> L*mg<sup>-1</sup>min<sup>-1</sup>. The inactivation of phage
that had first been pretreated with ozone and then exposed to 14 mg/L as Cl<sub>2</sub> monochloramine
had a rate constant of 3.91*10<sup>-3</sup> L*mg<sup>-1</sup>min<sup>-1</sup>, about 1.7 times faster than the non-pretreated ones.
However, significant tailing occurred in the sequential experiment, probably as a result of the
presence of viral aggregates. The precise reason for the tailing has not been fully investigated.
Additional research is needed to more fully characterize the observed synergistic effect. Includes 5 references, table, figure.
