“…There was no significant difference in inactivation of C. perfringens NCTC 8798 spores between pH 4.5 and 6.5 C102 treatment. Studying vegetative cells of bacteria, Ridenour and Ingols (1947) reported constant bactericidal activity in the pH range 6-10. Benarde et al (1965) reported no change in the absorption spectra of C102 at pH 4.0, 6.45, and 8.42 indicating dissociation of C102 in that pH range did not occur.…”

Bacillus cereus T and F48 1 O/72, B. stearorhermophilus ATCC 15 18, and Clostridium perfringens NCTC 8798 spore inactivation by 20, 50, and 80 mg chlorine dioxide (ClOz)/L at three pH values (4.5, 6.5, 8.5) were evaluated. C102 concentration, species and sporulation medium significantly (p < 0.001) affect spore sensitivity. B. cereus T sporulated in Modified G medium and B. srearothermophilus ATCC 15 18 are similarly C102 sensitive, and each is significantly more sensitive than Fortified Nutrient Agar-sporulated B. cereus T and F4810/ 72. The Bacillus spore populations are more C102 sensitive than C. perfringens spore populations. Treatment pH affects C. petfringens but not Bacillus inactivation. Spores lacking intact coats are significantly more CIOz sensitive than the strains with coats intact.

“…Chlorine dioxide was broad biocidal effectiveness. Cl02 has been reported to inactivate effectively bacteria (Ridenour and Ingols, 1947;Benarde et al, 1965), viruses (Cronier et al, 1977), bacterial spores , and algae (White, 1972). Information on the sporicidal activity of chlorine dioxide is limited.…”

“…for either gas, it was considered acceptable and stored, usually overnight, for testing purposes. Chlorine demand control checks were also run on this same dilution water at frequent 537 S O ME of the bactericidal properties of chlorine dioxide have been given in a previous report (1), in which the effect of the gas on Escherichia coli was investigated in artificial and natural waters and sewages. Other organisms in natural river pollution were also studied.…”

“…The data obtained in the studies to be described indicate that chlorine dioxide: [1] is bactericidal to the C0111mon water pathogens; [2] requires approximately the same practical residuals as chlorine to secure disinfection; [3] increases in efficiency with in- intervals during the bacteriological testing. These checks consisted of comparing chlorine residuals on the dilution water to the weights of chlorine applied.…”

“…Research on the use of chlorine dioxide for the disinfection of drinking water began in the 1940s with the pioneering work of Ridenour and Ingols (1947) and Ridenour and Armbruster (1949). Over the decades, it has been shown that chlorine dioxide has characteristics that made it a promising alternative to free chlorine.…”

The role of water quality (pH, temperature, turbidity, and natural organic matter (NOM)) on the efficacy of chlorine dioxide to inactivate Bacillus subtilis spores and MS2 phages was investigated in synthetic waters. Modelling the curves describing tailing inactivation with a parallel Chick-Watson model proved to be a valid approach. The formation of aggregates was exacerbated when using chlorine dioxide as opposed to free chlorine. The origin of these aggregates lies in the interactions of chlorine dioxide with the water matrix and the microorganisms. Higher temperature and higher turbidity were dominant factors in predicting spores tailing, while decreasing the pH from 8.5 to 6.5 was responsible for increasing the fraction of MS2 aggregates from 0.06% to 9.0% (138-fold). The resistance of aggregates were, on average, 18-21 times higher than for single organisms. The addition of dissolved organic carbon significantly (p < 0.01) improved inactivation with chlorine dioxide. Turbidity (5 NTU) did not significantly hinder MS2 inactivation, but it increased the concentration-time (Ct) 1-log of B. subtilis spores from 386 to 600 mg·min·L −1 .Résumé : Le rôle de la qualité de l'eau (pH, température, turbidité et matière organique naturelle) dans l'efficacité du dioxyde de chlore à inactiver les spores de B. subtilis et les coliphages MS2 a été étudié en utilisant des eaux synthétiques. La modélisation des courbes décrivant l'inactivation de la zone de traînée (« tailing inactivation ») par un modèle parallèle de Chick-Watson s'est avérée une approche valide. La formation d'agrégats a été exacerbée lors de l'utilisation du dioxyde de chlore par rapport au chlore libre. Ces agrégats émanent des interactions du dioxyde de chlore avec la matrice aqueuse et les microorganismes. Une température et une turbidité plus élevées étaient les facteurs dominants dans la prédiction de la zone de traînée des spores (« spores tailing »), alors que la diminution du pH de 8,5 à 6,5 a causé l'augmentation de la fraction d'agrégats de MS2 de 0,06 % à 9,0 % (138 fois). La résistance des agrégats étaient en moyenne de 18 à 21 fois plus élevée que celle des organismes solitaires. L'ajout de carbone organique dissous a grandement amélioré (p < 0,01) l'inactivation par le dioxyde de chlore. La turbidité (5 NTU) n'a pas vraiment nuit à l'inactivation des MS2, mais elle a augmenté le log Ct-1 des spores de B. subtilis de 386 à 600 mg·min·L −1 .
