The addition of powdered activated carbon (PAC) to activated sludge systems is a proven method of wastewater 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. The eleventh plant was designed for PAC use on a single pass basis as have essentially all of the industrial facilities using this technology. As part of this evaluation, all 11 POTWs were contacted to obtain basic design, O and M and performance data. Site visits were made to eight facilities to obtain more detailed information. The technology factors that were evaluated included effluent quantity, ash buildup, carbon losses, carbon analytical methodology, wet air regeneration, recycle loadings, operational/design modifications and costs. The results of the evaluations are presented.
