A Look at Activated Carbon Thermal Regeneration

Once the activated carbon has reached capacity, it can no longer be effectively used. The now “spent” carbon can either be sent to a landfill or incinerator for disposal, or recycled through regeneration. Typically powdered activated carbon (PAC) is not regenerated, but rather, disposed of, while granular activated carbon (GAC) is regenerated.
