  • Water treatment system with carbon regeneration circuit
    Patent number: 9096447
    Abstract: A water treatment system (50) utilizing granular activated carbon (GAC) for the removal of organic contaminants in a process water circuit (52), and including a carbon regeneration circuit (54) in fluid communication with the process water circuit. The carbon regeneration circuit may include a dedicated regeneration vessel (16), or the regeneration process may proceed within a GAC/water contactor (58) of the process water circuit. A process is described wherein spent GAC from the water treatment system is regenerated within the system with an oxidation process that minimizes damage to the carbon granules.
    Type: Grant
