Disinfection of Phytophthora spp. in Recycling Nursery Irrigation Water by Ozone Treatment

Synergies of UV Disinfection and Ozone in Water Treatment

Two case studies outlining the benefits of using ozone and UV are presented in this paper. They demonstrate the cost effectiveness and robustness that can be observed when the synergies of these two treatment alternatives are utilized. In the first study, ozone and UV disinfection were used at the Weber Basin Water Conservancy District’s Water Treatment Plant No. 3. The ozone system was designe...

Endodontic disinfection – tsunami irrigation

XX There are enormous differences in opinion regarding the potential to three-dimensionally clean a root canal system. Elimination of pulpal tissue, bacteria when present, and their related breakdown products is directly influenced by a series of procedural steps that comprise start-to-finish endodontics. Regrettably, there is no single beacon of light to brightly illuminate the most proven cli...

Reduction of Norwalk virus, poliovirus 1, and bacteriophage MS2 by ozone disinfection of water.

Norwalk virus and other human caliciviruses (noroviruses) are major agents of gastroenteritis, and water is a major route of their transmission. In an effort to control Norwalk virus in drinking water, Norwalk virus reduction by bench-scale ozone disinfection was determined using quantitative reverse transcription (RT)-PCR for virus assays. Two other enteric viruses, poliovirus 1 and coliphage ...

Disinfection of water containing natural organic matter by using ozone-initiated radical reactions.

Ozone is widely used to disinfect drinking water and wastewater due to its strong biocidal oxidizing properties. Recently, it was reported that hydroxyl radicals ((.)OH), resulting from ozone decomposition, play a significant role in microbial inactivation when Bacillus subtilis endospores were used as the test microorganisms in pH controlled distilled water. However, it is not yet known how na...
