powder activated carbon regeneration

Regeneration of spent activated carbon (Technical Report

The addition of powdered activated carbon (PAC) to activated-sludge systems is a proven method of waste water treatment. Of eleven POTWs in the U.S. that were designed for PAC use, ten included wet-air regeneration (WAR) for the destruction of secondary-sludge solids and recovery of spent PAC.

MICROWAVE REGENERATION OF SPENT POWDER ACTIVATED CARBON

Abstract Experiments were conducted to demonstrate that spent powder activated carbon can be regenerated for reuse by microwave radiation. The spent powder activated carbon tested was prepared from the aqueous solutions of ethanol and acetone. The changes in the temperature and weight of spent activated carbon under microwave radiation were monitored.
