In killing HA V and Coliform the best temperature is 10°C
HOW OZONE KILLS MICROORGANISMS
●
Ozone can combine with amino acid and breaks the protein in these bodies
●
Ozone destroys viruses by diffusing through the protein coat into the nucleic acid core,
resulting in damage of the viral RN. At higher concentrations, oxone destroys the
capsid or exterior protein shell by oxidation.
●
In Gram negative organisms, fatty acid alkyl chains and helical lipoproteins are present
●
Ozone may also penetrate the cellular envelope, directly affecting cytoplasmic integrity,
disrupting any one of the numerous levels of its metabolic complexities
APPLICATIONS
Water Treatment
●
Ozone can effectively kill bacteria and virus, can remove the organic impurities in the
water.
●
It can remove odour and be used as a bleaching agent too.
●
Chlorine is widely used in water treatment practice; it generates harmful substances
such as chloroform in the process of treating water. Ozone will not generate
Chloroform. Ozone is more germicidal than chlorine. It has been widely used in water
plants in the USA and EU.
●
Chemical Ozone can break the bonds of organic compounds to combine from new
compounds. It is widely used as an oxidant in the chemical, petrol, papermaking and
pharmaceutical industries.
Food Industry
●
Because ozone is a safe, powerful disinfectant, it can be used to control biological
growth of
●
unwanted organisms in products and equipment used in the food processing industries.
●
Ozone is particularly suited to the food industry because of its ability to disinfect
microorganisms without adding chemical by-products to the food being treated or to the
food processing water or atmosphere in which food is stored.
●
In aqueous solutions, ozone can be used to disinfect equipment, process water and
some food items and neutralise pesticides
●
In gaseous form, ozone can act as a preservative for certain food products and can
also sanitize food packaging materials.
●
Some products currently being preserved with ozone include eggs during cold storage,
fresh fruits and vegetables and fresh seafood.
Medical
●
Ozone has been used in hospitals and clinics as a disinfectant in China, Germany and
other developed and developing countries.
●
Ozone is more germicidal than formalin, acidum peroxyacetic and potassium
permanganate.
