Abstract
An activated carbon filter is regenerated while it remains positioned in a filter vessel by first draining both unfiltered and filtered water out of the vessel and then applying an electric current through the activated carbon body of the filter to drive off contaminants. An inert gas is directed through the filter in a direction opposite to that of the liquid flow and then contaminants are moved from the filter vessel to a multi-stage catalytic converter where they are completely oxidized.
