The application of ozone is divided into four fields: water treatment, chemical oxidation, food processing and medical treatment according to the purpose. The applied research and the development of applicable equipment in each field have reached a very high level.

1. water treatment

  Ozone disinfection equipment has a high rate of killing bacteria, viruses and other microorganisms in water, and the speed is fast, and it can completely remove pollutants such as organic compounds without causing secondary pollution. The industry is a stinky market.

 As water sources are polluted by organic chemical industrial products, chlorinated organic compounds such as chloroform, dichloromethane, and carbon tetrachloride will be produced after chlorine disinfection. These substances are carcinogenic, while oxidation in ozone treatment does not produce secondary pollution compounds.

2. chemical oxidation

 Ozone is used as an oxidizing agent, catalyst and refining agent in the chemical industry, petroleum, papermaking, textile and pharmaceutical, and fragrance industries. The strong oxidizing ability of ozone can easily break the carbon chain bonding bonds of alkenes and alkynes, so that they can be partially oxidized and combined into new compounds. 

 Ozone plays an important role in the purification of biological and chemical polluted gases. The stench of fur, casings and fish processing factories, and the polluted gas of rubber and chemical factories can be deodorized through ozone decomposition. The United Kingdom regards the combination of ozone and ultraviolet rays as the preferred technology for treating chemically polluted gases, and some applications have achieved good results.

 Ozone catalyzes the synthesis of pesticides, and can oxidize and decompose some pesticide residues. The Naval Medical Research Institute has conducted in-depth research on the removal of pesticide residue pollution by ozone, and has affirmed the good effect of ozone.

3. food industry application

 The strong bactericidal ability of ozone and the advantages of no residual pollution make it widely used in the disinfection and deodorization, anti-mold and fresh-keeping aspects of the food industry.
