Description
The effect of the sequential application of ozone followed by monochloramine on enteric viruseswas investigated using MS2 phage as a surrogate. All experiments were performed in 0.01 Mphosphate buffer solution at pH 7.0¿¿¿¿0.1. The inactivation of MS2 phage exposed tomonochloramine alone at a concentration of about 21 mg/L as Cl<sub>2</sub> was found to follow first-orderChick-Watson kinetics with rate constant k = 2.24*10<sup>-3</sup> L*mg<sup>-1</sup>min<sup>-1</sup>. The inactivation of phagethat had first been pretreated with ozone and then exposed to 14 mg/L as Cl<sub>2</sub> monochloraminehad 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 thepresence 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.
