Optimized carbon performance on repeat

GAC reactivation is the most cost-effective, sustainable path forward for municipalities managing long-term carbon supply.

Your spent carbon is a strategic asset, and GAC reactivation is your key defense against rising costs and long-term environmental liability. While others simply dispose of spent media, Calgon Carbon closes the loop, transforming your spent carbon into a high-performance solution that outlasts and outperforms the status quo.

Why municipalities choose reactivation:

Reduce liability, don't move it

Thermal reactivation destroys PFAS to near non-detect levels, avoiding the landfill.

Lower costs for utilities

Shield your budget from virgin carbon price volatility with a circular supply chain.

Scale without compromise

Access North America’s largest RCRA-permitted reactivation network.

Minimize your carbon footprint

Cut CO2 impact by 80% and meet sustainability goals with a recycled solution.

Water utilities value predictability. So do we.

By switching to a closed-loop GAC reactivation strategy with Filtrasorb Rx, you replace operational anxiety with a concrete pillar of technical certainty. Move toward a more resilient infrastructure and, above all, say goodbye to:

Generic custom municipal reactivation solutions add uncertainty at every stage of ownership.

Filtrasorb Rx delivers the tailored performance others can’t.

“We built Filtrasorb Rx because utilities deserve a reactivation solution held to the same rigorous standards as their treatment process. Now they have one.”

Frequently Asked Questions:

Why did Calgon Carbon move away from the name “CMR”?

CMR describes a process, not a product.

Filtrasorb Rx places reactivated carbon under the trusted Filtrasorb master brand, creating a name that everyone can recognize, specify, and defend in budgets.

Calgon Carbon’s peer-reviewed reactivation process is only one aspect to realizing the reactivated product performance. The starting feedstock is another critical part to performance.

How does Filtrasorb Rx differ from generic reactivated carbon?

Filtrasorb Rx is:

Your carbon returned to you, not pooled or swapped
Based on Filtrasorb virgin grades

Backed by peer‑reviewed, full‑scale reactivation studies

- Our process is proven to remove organics like PFAS from the spent carbon to non-detect levels

- Our process is proven to destroy PFAS to >99.9% Destruction Removal Efficiency

Supported by Calgon Carbon’s technical, logistics, and field service teams
The only reactivated media to use Filtrasorb virgin carbon for make-up supply post reactivation.

Other reactivated carbons may not offer the same level of consistency, transparency, or accountability.
