What is Ozonated Water

What is Ozonated Water?

Ozone is a colorless and odorless gas comprising three oxygen atoms. 
When ozone is dissolved in water, the water becomes ozonated and its antioxidant and antimicrobial properties are thought to have some therapeutic benefits. Its powerful disinfection, deodorization, and antibacterial capabilities are widely used in today's industrial,commercial and residential applications.
 

How it’s made

Making ozonated water involves filling a container with purified water while an ozone gas mixture bubbles through it continuously. This occurs for at least 5 minutes until maximum saturation has taken place. Then, the ozone gas will have fully dissolved into the water.


 
Compare to HOCI Water,Rubber Alcohol
Rubber alcohol HOCI Water ozone water
Sterilization efficiency High★★★ Medium★★ High★★★★
Bacteria type ★★★60-80% concentration inactive against most bacteria and enveloped viruses ★★Inactive against most viruses, molds, fungi and spores. ★★★★All microorganism
Contact time A few seconds From a few minutes to a few hours A few seconds
biodegradable High★★★ Low★★ High★★★★
Storage Yes Unstable, afraid of light and heat, and its bactericidal effect will decrease over time. It will be oxidized and reduced to water after standing for 20 minutes
Corrosive A highly corrosive disinfectant, some metals will be corroded by alcohol. It corrodes tissue cells and forms chloroform, leading to serious cancer problems. Corrosive to iron and stainless steel at high concentration (hundreds of ppm)General ozone water is non-corrosive since low concentration.
Toxicity Industrial alcohol contains methanol, which can cause poisoning. Medical alcohol is ethanol, which can be used for disinfection and sterilization. Corrosive to iron and aluminum materials. Ozone dissolves into water, at normal concentrations, its toxicity is negligible.
Residue on food Not for rinsing food. It may cause skin irritation due to long time use. Food residue cannot exceed 1ppm. It may cause skin irritation due to long time use. No residue on food,suitable for cleaning, sterilizing, and removing pesticide residues.
Influence on skin Not suitable for skin allergic to alcohol Strong oxidant , irritating to skin. less irritating to skin.
Property Medical alcohol is ethanol, which can be used for disinfection and sterilization. Not only does it smell like chlorine ,it also contains carcinogens such as humic acid that produce chloroform. It will decompose into oxygen with no chemical residue, which is the biggest feature.
           Comparison between ozone and other disinfectants
**Efficacy**: Ozone is a more powerful disinfectant compared to chlorine, especially against protozoa, which chlorine cannot deactivate. Detailed data-See Table 1.
Table 1: Ct-values for the deactivation of viruses by various disinfectants
Disinfectant Units Inactivation
  2-log 3-log 4-log
Chlorine(1) mg.min/L 3 4 6
Chloramine(2) mg.min/L 643 1067 1491
Chlorine Dioxide(3) mg.min/L 4.2 12.8 25.1
Ozone mg.min/L 0.5 0.8 1
CT values were obtained from AWWA,1991
(1)Values are based on a temparature of 10℃,pH range of 6 to 9,and a free chlorine residual of 0.2 to 0.5mg/L.
(2)Values are based on a temparature of 10℃ and a pH of 8.
(3)Values are based on a temparature of 10℃ and a pH range of 6 to 9.
**Environmental Impact**: Unlike conventional disinfectants like chlorine or ultraviolet, ozone dissolved in water is more eco-friendly .
**Effectiveness Against Different Microorganisms**: Ozone has shown high effectiveness against bacteria, fungi, and molds, and inactivating viruses on surfaces and in the air.
     More Effectiveness Data
**Long History in Water Treatment**: Ozone has been used in water treatment for over a century,particularly for disinfection and oxidation, and in recent times for micropollutant abatement and potable water reuse.
**Preserving Food Quality**: In the food industry, ozone water has demonstrated effectiveness inmaintaining the visual appearance and controlling browning of fresh-cut fruits and vegetables during storage.
**Ozone Reaction Applications**: The reliable generation and robust reactive properties of ozonemake it a valuable tool in drinking water disinfection and other applications.
**Studies show that Ozone acts 3,000 times faster than chlorine and is 50 times more effective
Compare with other common disinfection products,such as HOCI Water,Rubber Alcohol..etc.,ozonated water has relative product advantages.
  • Broad Spectrum Effectiveness: Ozone is effective against a wide range of pathogens, including protozoan cysts and oocysts, bacteria, viruses, fungi, spores, and molds.
  • Pandemic Response: Ozone has been shown to effectively kill SARS-CoV-2 on various surfaces and in water and aerosols, proving its utility in pandemic situations.
  • Eco-Friendly: Ozone is environmentally friendly, causing no secondary hazards to the environment post-administration.
