Here is an article i found. You may all have seen or heard it, but just a reminder where we are headed. People are taking notice! from: enn.com The honorable side of ozone Say the word ozone in a room full of environmentalists and you are likely to hear groans and laments about this destructive air pollutant. But, while the groaning is stirred up even further with words like the greenhouse effect and global warming, ozone researchers have discovered that when generated artificially and applied under controlled conditions, ozone can solve a number of pressing environmental problems. Over the years, ozone research sponsored by the Electric Power Research Institute has branched into a variety of areas, exploring ozone's effectiveness as a disinfectant for drinking water, as a bleach and detergent substitute in large-scale laundry facilities, and as a way to treat several kinds of industrial wastes. Perhaps one of the most dramatic EPRI-instigated achievements on the ozone front is an expert panel's recent affirmation of "generally recognized as safe" status for ozone as a sanitizer or disinfectant for foods. This affirmation was delivered to the FDA in April and clears the way for ozone's use in the $430 billion food processing industry. Ozone can be used as a gas to disinfect a room for food storage or added to water to wash food. A current study is investigating the potential for using ozone to control insect infestation during food storage. This would provide an environmentally benign alternative to fumigants now being phased out. Ozone's health and environmental benefits are working to secure it a place in a wide variety of other markets. Today more than 200 U.S. drinking water plants use ozonation and the number is expected to climb. EPRI has researched claims that ozone is far more effective than conventional disinfectants against the microbial contaminants -- including Escherichia coli, Salmonella, Giardia, and chlorine-resistant Cryptosporidium -- that have invaded food and water supplies and claimed numerous lives in recent years. Ozone isn't always used as a disinfectant in water treatment. It can also be used as an oxidant. In fact, the city of Orlando, Fla., is building five full-scale plants to oxidize hydrogen sulfide, which causes "rotten egg" taste and odor problems in the local water. As EPRI's Myron Jones notes, there are scores of other possible applications of ozone still left to explore. "Basically, any application that calls for purification or oxidation can potentially benefit from ozone," says Jones. "The possibilities are endless."
