ABSTRACT:
In a carbon contact column for a system for removing certain organic compounds from waste water, carbon supplied to the column flows in counter-current contact with the stream of waste water flowing through the column. Carbon is removed from the bottom of the column by a jet eductor. A source of fluidizing water is connected to the column adjacent to the eductor to prevent the formation of a cavity in the carbon bed in that area adjacent to the jet eductor.
