The reactivation process recycles spent carbons into new activated carbon materials that continue to provide excellent performance in many treatment applications. Reactivation can be applied to carbons used in both liquid phase and vapor phase applications. Spent carbons can be segregated from other spent carbons and returned to the same customer for reuse, or pooled with other spent carbons and sold into other applications as a cost-effective alternative to virgin carbon. Evoqua has extensive experience with all of these types of reactivation services.
With three spent carbon reactivation facilities (Darlington, PA, Parker, AZ and Red Bluff, CA), Evoqua Water Technologies is a leader in spent carbon reactivation. The Darlington and Parker facilities are both permitted to process RCRA hazardous spent carbon, making Evoqua the only supplier with permitted capacity serving both the East and West Coasts. The Red Bluff facility is the largest non-hazardous carbon reactivation facility in the western United States. Both the Darlington and Red Bluff facilities are capable of supplying custom reactivated carbon for potable applications that meet ANSI / NSF Standard 61.
Our reactivation facilities can process RCRA hazardous and non-hazardous liquid and vapor phase spent carbons. After inspection and acceptance, the spent carbon is heated to 1600° F to ensure proper reactivation. The cooled reactivated carbon is identified by lot numbers, sampled and analyzed in accordance with our QA/QC program. This process assures the highest quality reactivated carbon.
The entire state-of-the-art process is computer controlled and monitored, ensuring that the facilities meet or exceed federal and state regulatory requirements for air and water discharges. A “Certificate of Reactivation” can be issued for each shipment of recycled carbon. This certifies that the spent carbon has been recycled in a manner that meets or exceeds all applicable RCRA and Benzene NESHAP and Subpart CC regulations.
