It is a well-known fact that ozone, a very strong oxidant, is used in water treatment disinfection.. It shows an extensive range of applications; drinking water, wastewater, water disinfection, color removal, micropollutants, pulp & paper bleaching, process water, ballast water, cooling towers, beverage and water bottling, aquaculture, aquariums (zoos), cyanide regeneration, food/ produce ...
Ozone MNB gives the same inactivation rate same like conventional ozonation for the target pathogen E.coli, but here in the case of microbubble technology, the ozone dose was lower. [23] As higher mass transfer leads to lower ozone dosage so, this ozone MNB technique is promising and beneficial for the existing water treatment plants. [24]
Ozone has been used in drinking water plants since 1906 where the first industrial ozonation plant was built in Nice, France. The U.S. Food and Drug Administration has accepted ozone as being safe; and it is applied as an anti-microbiological agent for the treatment, storage, and processing of foods.
For water treatment, CWTP utilizes four ozone generators, designed to handle an average capacity of 275 million US gallons (1,040 million litres) per day—although average daily consumption is lower, at approximately 200 million US gallons (760 million litres)—and a peak level of 405 million US gallons (1,530 million litres) per day.

Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
A mixed oxidant solution (MOS) is a type of disinfectant that has many uses including disinfecting, sterilizing, and eliminating pathogenic microorganisms in water. [1] An MOS may have advantages such as a higher disinfecting power, stable residual chlorine in water, elimination of biofilm, and safety. [2]
