BACKGROUND INFORMATION:
Granular activated carbon (GAC) treatment systems (Attachment1) are currently utilized at nine well sites to treat and adsorb dibromochloropropane (DBCP), 1,2,3,- trichloropropane (1,2,3-TCP), and other contaminates found in drinking water. Over time, the carbon loses its adsorptive capacity and must be replaced or regenerated. Historically, when replacement has been warranted, the City has chosen to replace with virgin coal GAC. When only treating DBCP, virgin coal GAC can usually run 6 to 10-years without requiring replacement. In 2017, the Maximum Contaminant Level (MCL) for 1,2,3-TCP was set at 0.005 ?g/L or 5 parts per trillion. This MCL is now triggering more frequent GAC change-outs.
In 2023, due to the increased change-out frequency, staff researched alternatives in an effort to reduce cost and ensure product availability, while still procuring a high-quality product. GAC regeneration is an efficient, cost- effective alternative to virgin GAC. GAC regeneration is a thermal reactivation process where adsorbed organics are destroyed by extreme heat and the activated carbon's adsorptive capacity is restored.
On March 25, 2023, Council approved the first GAC regeneration contract with Calgon ...
