Water Research Volume 160, 1 September 2019, Ozone disinfection of chlorine-resistant bacteria in drinking water. Highlights Chlorine-resistant bacteria were easier to inactivate by ozone than spores.
Bacillus cereus spore inactivation rate reached 99.9% after ozone treatment. O3 disinfection inactivated spores by damaging cell surfaces and genetic material. Abstract The wide application of chlorine disinfectant for drinking water treatment has led to the appearance of chlorine-resistant bacteria, which pose a severe threat to public health. Keywords. Ultrasonics Sonochemistry Volume 40, Part B, January 2018, Ultrasound-assisted advanced oxidation processes for water decontamination. Dedicated to my Ph.D. students in the past and the present.
Highlights Azo dyes can easily be bleached by sonication, but complete destruction requires advanced oxidation (AO) or catalytic processes, preferably assisted by ultrasound. Endocrine disrupting compounds are “emerging” water contaminants; elimination by ultrasound is sensitive to structural and operational parameters. Degradation of a-PhACs in water by ultrasound is limited, unless integrated with advanced and catalytic oxidation processes. Decoration of TiO2 surface with noble metals improves the activity of the semiconductor and the modified catalyst is reusable. Abstract. FOOD MANUFACTURING 16/09/09 Drive For Food Safety Increasing Use Of Ozonated Water Systems.
With food safety as a growing business imperative, an increasing number of food processors, restaurants and supermarkets are turning to ozonated water systems for improving disinfection.
Researchers have verified that ozonated water can replace traditional sanitizing agents like chlorine and detergents (if grease must be removed, ozone cannot replace detergents) and reduce the incidence of food-borne illness due to food pathogens. And the use of ozonated water can drive profitability by increasing the freshness and shelf-life of produce, meats, fish and poultry, while reducing the need for and cost of chemical cleaning agents and hot water (energy).
Chlorine is commonly used in food processing to control pathogens, yet there are limitations in its ability to provide a consistently safe food supply. The disinfectant potential for ozone is evidenced by its use by water treatment facilities in the U.S. and Europe. ROI in 4 Months Food looks fresher, fish odor is eliminated.

WATER QUALITY PRODUCTS - Ozone Regulations. Ozone, O3, a triatomic gaseous form of oxygen, is an unstable molecule that is naturally occurring in nature.
It is known as the world’s most powerful commercially available disinfectant and is used in a variety of industries, from drinking water to industrial water treatment to food processing. Reactions Disinfection. Ozone destroys viruses and parasites such as Giardia and Cryptosporidium. A U.S. Chemical oxidation. Decomposition. History While ozone was considered a “chemical curiosity” after its 18th century discovery, its value was quickly engaged by the scientific community.
Ozone technology gained momentum in the 1970s with increasing scrutiny regarding pollution and with the advent of contamination problems in the bottled water industry. Regulations—A Hierarchy of Acronyms Ozone is applied in a diverse array of industries, including drinking water, food processing, agriculture/aquaculture, cooling towers, semiconductors, laundry and air treatment, and many more.

Le Monde.fr | • Mis à jour le | Par Pierre Le Hir Un polluant – l’ozone – peut se transformer en très efficace agent de dépollution. C’est la voie explorée par l’Institut polytechnique LaSalle-Beauvais (Oise) et l’Agence de l’environnement et de la maîtrise de l’énergie (Ademe). Elle pourrait déboucher sur un procédé innovant de décontamination de nappes phréatiques et de sols. Le pouvoir désinfectant de l’ozone est connu et exploité de longue date, notamment dans le traitement des eaux usées. Mené pendant trois ans par les deux partenaires, qui en ont financé à égalité le coût (600 000 euros), le programme de recherche OPOPOP (optimisations des paramètres d’ozonation en phase liquide pour des polluants multiples de sites pollués) s’achèvera mi-septembre.
