Contaminants are filtered from a fluid flow stream and the filter is regenerated by a process including steps of:providing a filter material comprising both carbon and potassium iodidepassing a contaminated fluid stream in contact with the filter materialadsorbing contaminants from the fluid stream onto surfaces in the filter materialpassing an electric current through the filter material with adsorbed contaminant thereondisassociating contaminant from the surfaces of the filter material andremoving disassociated contaminant from the filter material by carrying away the disassociated contaminant in a fluid flow mass.Separately, a stable, active iodine solution is also provided for numerous deodorizing and disinfecting applications.
