A Laboratory Filtration System Kills 100 Percent Of Dangerous Microbes In Water

Fenton reaction - a process wherein metal catalysts cause hydrogen peroxide to produce large numbers of free radicals.

Free radicals are atoms or molecules that have an extra electron in dire need of a partner (they obtain the partner by stripping it from a nearby atom, damaging the "victim" in the process). In large quantities, the radicals can destroy toxic chemicals and even bombard bacteria to death or irreparably damage a microorganism's cell membrane.

Applying their technique to water from the Industrial and 17th Street canals in New Orleans, the researchers were able to destroy all of the bacteria within 15 minutes. In tests with laboratory water samples containing even higher bacterial concentrations, the exact same process killed at least 99 percent of the bacteria in 90 minutes.
