Ozone killing of key pathogens
Dissolved ozone at only 0.6 ug/L – inactivates E. coli (4 logs in 1 minute) – similar for Staphyloccus sp. and Pseudomonas fluorescens inactivation. Streptococcus faecalis requires 2 mins contact time at the same dissolved ozone conc.
- More effective than chlorine, chloramines, and chlorine dioxide for inactivation of viruses, Cryptosporidium, and Giardia.
- Controls colour, taste, and odours.
- Very short contact time.
- Upon decomposition, the only residual is dissolved oxygen.
- Biocidal activity is not influenced by pH.

2 minutes treatment showed reduction from 5200 to 300 CFU/ml after first application, then 0 CFU/ml at the second & subsequent uses.The treatment of DUWL with ozone gave rise to a substantial reduction in many of the microbial catabolites.
