Granular Activated Carbon Regeneration Technology
A New Method for
an Old Problem
Battelle has pioneered a method of reactivating GAC on-site–eliminating the need to ship it back to the vendor. This innovative approach to GAC regeneration reduces operating costs and lengthens the life of the system. This is environmental science that saves time, money, and energy.
Exclusive Technology Services. Total PFAS Destruction.
Battelle is dedicated to applied research and development and technology optimization in environmental investigation and remediation. We are launching Revive Environmental to deploy PFAS Annihilator™ and GAC Renew™ at scale for maximum impact.
How It Works
Battelle’s solvent-based technology for on-site GAC regeneration includes at least two tanks of GAC. One tank is taken offline while the second tank allows GAC treatment to continue uninhibited during regeneration. The regenerant solution is stored on site and is cycled through the tank for the number of bed volumes (determined during laboratory column studies) that best regenerate the GAC. The spent regenerant solution is distilled for recycling. After the solution has regenerated the spent GAC, potable water is passed through that tank to rinse the GAC before putting it back online.
Features of Our GAC RENEW™ Technology
- Can effectively reactivate GAC using solvent-based technology
- Better PFAS removal is obtained from the solvent-regenerated GAC than virgin GAC, even after four solvent-regeneration cycles
- Spent regeneration solution can be distilled for recycling and the concentrated distillate treated on site with Battelle’s PFAS ANNIHILATOR™ Destruction Technology
