Abstract:
There are provided herein methods and systems for increasing efficiency in a multi-stage activated carbon system. The methods and systems provide a cleaned carbon solids fraction and a waste liquor from wet air regeneration, and direct the same to a second stage and a first stage, respectively, of the multi-stage activated carbon system to enhance removal efficiency therein.

Claim (Index 1):
A method for treating wastewater comprising:\n treating an amount of wastewater in a powdered activated carbon treatment (PACT) system comprising a first stage and at least a second stage, each stage comprising an amount of powdered activated carbon therein, wherein the treating removes at least one contaminant from the wastewater and produces a spent carbon material; directing an amount of the spent carbon material to a wet air regeneration system (WAR) for regeneration of the spent carbon material; separating an effluent from the WAR system into a cleaned carbon solids fraction and a waste liquor; directing the cleaned carbon solids fraction to the second stage; and directing the waste liquor to the first stage for use in treating additional wastewater ( 108 ) in the first stage, thereby relieving the second stage from gross pollutant removal and allowing the second stage to serve as a polishing step to remove first stage effluent contaminants.
