PFAS removal from water

Clean the carbon. Keep the carbon.

Fluorinse™ regenerates PFAS-loaded granular activated carbon (GAC) on site. The carbon goes back into service; the PFAS leaves as a small, concentrated waste.

Greater than 50% cost savings

>50% cost savings for a stationary or central regeneration system compared with conventional GAC replacement system for a 2.4 MGD (379 m³/h) system, based on a cost model developed with a utility partner.

For a mobile system, savings are potentially greater than 70%.

Where Fluorinse™ fits among PFAS treatments

Destroy it, capture it with better adsorbents, separate it into a concentrate, or make the GAC utilities already run much cheaper. Fluorinse™ takes the fourth path. Compare the options

Today, the carbon leaves the site every time

When PFAS breaks through, tonnes of spent carbon are hauled away, reactivated or landfilled, and replaced. Each disposal route risks releasing PFAS again. See today's GAC cycle

How it works

Fluorinse™ regeneration in five stepsAdsorb, desorb, flush, agglomerate, remove. 1 Adsorb 2 Desorb 3 Flush 4 Agglomerate 5 Remove
  1. PFAS collect on the GAC, as in any GAC system.
  2. A Fluorinse™ fluid draws the PFAS off the carbon.
  3. The PFAS are flushed out of the bed.
  4. Outside the bed, the PFAS form clusters.
  5. Filters capture the clusters before the fluid is reused.

Why it matters

Cost

Greater than 50% cost savings for a stationary or central system vs conventional GAC.

Waste volume

PFAS leaves in filters. The volume to destroy is orders of magnitude smaller.

Carbon footprint

An estimated 90–99% lower footprint.

Mobile system concept

A mobile unit regenerates the carbon at the customer's site, and the same carbon goes back into service. The rendering below is a concept, not yet a commercial service.

Concept illustration of the mobile system.
Mobile system conceptA truck brings an empty tank to the site. Spent carbon moves from the customer's GAC vessel into the tank as a slurry, is regenerated on site and returns to the vessel. Filters holding concentrated PFAS are the only waste that leaves. Mobile tankarrives empty Customer GAC vessel GAC bed spent GAC out as slurry regenerated GAC back in Filters concentrated PFAS leaves in filters,for disposal or destruction no new media delivered;site water used and reused
~2 barrelsTotal waste, nearly all to landfill, minimal incineration
Orders of magnitudeLess PFAS concentrate to destroy than the spent media volume
~50, not 1,000 kgTo destroy, vs carbon that is not reactivated: 95% less

Fluorinse™ complements, rather than competes with, emerging PFAS destruction technologies: it gives them far less to destroy.

  • Less than 8 hours on site overall.
  • Only the filters leave All PFAS is caught in filters, cleaned or destroyed on site, on a trailer or at a central plant.
  • Site water only reused step to step and, in many cases, discharged locally.
  • Low media loss from slurry loading and a fluidized-bed process.
  • Familiar service much like a change-out today.
