What is Ozone?

Ozone, the first allotrope of a chemical element to be recognized by science, was proposed as a distinct chemical compound by Christian Friedrich Schönbein in 1840.

Ozone (O3) is an activated form of oxygen. It is a highly reactive gas composed of three oxygen atoms in one molecule. This additional atom makes ozone a very strong disinfectant, a powerful deodorizer and a potent oxidizer. It is a powerful oxidizing agent. Any pathogen or contaminant that can be disinfected altered or removed via an oxidation process will be affected by ozone. It is the strongest of all molecules available for disinfection.

  • 1840 Discovered by Schönbein
  • 1893 Used as a disinfectant in drinking water
  • 1909 Used as a food preservative for cold storage of meats
  • 1939 Research to Prevent the growth of yeast & mold
  • 1982-95 Ozone Used in bottled water Application

Safety
Ozone is attractive as an alternative to chemical processes like chlorine, which present significant safety challenges.
The USDA and FDA have approved ozone for use with food meant for human consumption.

  • OSHA requires that ozone levels around workers remain below 0.1 ppm
  • The USDA and FDA regulate how ozone may be used in food.
Ozone levels in Air should never exceed the following average: 0.10 ppm (parts per million) for 8 hours per day exposure.

Ozone is an unstable molecule which quickly changes back to oxygen. The time for half of the ozone in air to decompose (half-life) is in minutes depending on the temperature and humidity of the ambient air.

The half-life in clean water is about the same.
Note: the temperature, pH, and water quality will affect half-life.

Ozone cannot be stored or transported and has to be Produced On Site

Ozone gas has been widely accepted as one of the form of treatment for drinking water and due to the easily availability of these small output ozone generators, today Ozone water treatment plants are very much in demand for Drinking water for Societies, Complexes, Buildings, Offices, Factories, Hotels, Bottled Water Plants Mineral Water Plants, Water treatment plants and also independent Ozone Water treatment plant along with a filteration are also sold

Increase in Human Consumption of water which exceeds the demand for fresh water results in Contamination of water by different Pathogens

Ozone treatment is quite efficient and effective in achieving pollution removal allowing people more flexibility to use water that exists where they are.

Because of its excellent disinfection and oxidation qualities, Ozone gas is widely used for drinking water which can be added at several points throughout the treatment system, such as during pre-oxidation, intermediate oxidation or final disinfection.

Ozone for drinking water has to be used as an Oxidant for Organic compounds, Odor and color removal in water Dosage varies depending upon various factors

Ozone gas can be Validated in dissolve Water and Ambient Air Using Ozone Sensors from Some applications and Ozone gas can be destructed using UV or Thermal or Catalyst Devices.
