Abstract
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 iodide; passing a contaminated fluid stream in contact with the filter material; adsorbing contaminants from the fluid stream onto surfaces in the filter material; passing an electric current through the filter material with adsorbed contaminant thereon; disassociating contaminant from the surfaces of the filter material; and removing disassociated contaminant from the filter material by carrying away the disassociated contaminant in a fluid flow mass.
Claims14
An apparatus for removing contamination from a fluid stream comprising:
- a) a housing containing a filter material having two opposed surfaces, the filter material comprising carbon and an activating agent selected from the group consisting of an alkali metal halogen and an alkaline halogen, the filter attracting a contaminant;
- b) a fluid inlet port to the housing;
- c) a fluid outlet port from the housing with a fluid flow path between the fluid inlet port and the fluid outlet port and over the filter material;
- d) a source of contaminated fluid containing said contaminant available to the fluid inlet port and then to the fluid flow path;
- e) the fluid flow path positioned i) for moving the contaminated fluid through the inlet port and through the filter material and over the filter material to adsorb the contaminant onto one opposed surface of the filter material and ii) then move later dissociated contaminant in a flowing fluid mass to the outlet port;
- f) a source of direct current passing through the filter material comprising two electrodes, each of the two electrodes facing the opposed surfaces of the filter, the source of direct current supporting voltages between 0.5 and 30V between the two opposed surfaces to generate the later dissociated contaminant by the direct current overcoming forces binding adsorbed material to one of the two opposed surface of the filter material and into the flowing fluid mass.
