Specialized News and How To Tips - Ozone

I had read many report about the Chlorine have cause miss-carriage & other issue like skin cancer or cancer... Therefore, the industry now have shifted to ward using Ozon as a dis-infectants of Water & other products.

Here is the writing I attache for the awareness purpose.

Traditional methods revolve around the use of chemicals such as chlorine in the sanitizing of produce, specifically in rinsing and washing. Chlorine is widely used in these processes but it has a limited effect in killing bacteria on fruit and vegetables surfaces. There is also wide concern with regards to the by-products of chlorine and its effects on health and the environment.

Ozone is becoming a popular alternative solution to traditional sanitizing agents and providing additional benefits. Ozone is an oxidizing agent, 1.5 times more powerful than chlorine and effective over a much wider spectrum of microorganisms. Ozone kills viruses and bacteria such as Escherichia coli and Listeria much faster than chlorine and other chemical agents and is free of chemical residues as it decomposes into simple oxygen.

Disinfection of Process Water

Raw water can contain traces of pesticides and toxic organic compounds which when combined with chlorine can produce harmful chlorinated compounds. Process water may also become contaminated by bacteria in storage tanks or piping. In both cases, poor water quality may have an effect on the overall quality and safety of the final product. Ozone as been proven to be an effective treatment for these contaminants without the formation of by-products. Ozone has also been shown to be effective against chlorine-resistant microorganisms such as Cryptosporidium and Giardia, which have caused several deaths in recent years.

Produce Washing and Rinsing

Spray and fume washing systems using ozonated water can be used to greatly reduce microbial counts on the surface of the produce. Contamination of produce arises in the field as a result of pesticides as well as during storage, transport and packaging. Ozone is particularly effective against E. Coli, the food pathogen of most concern in the food industry.

Process Water Recycling

It is estimated that more than 50 billion gallons of fresh water are used by the produce industry each year in the US. With the increasing difficulty in sourcing large quantities of water as well as wastewater treatment costs, a need exists to decrease the amount of water used. Ozone is very effective in the treatment of water for recycling as it can be used to remove color, odor, and organic load.
