Foam Fractionation

Foam Fractionation is most used in applications with high concentrations of PFAS and co-contaminants. Foam Fractionation Treatment using FOAM-X™ is the technology that ECT2 applies to these highly contaminated waters, such as groundwater remediation, wastewater treatment, and landfill leachate management.


  • Effective on high concentrations of PFAS
  • Works well with co-contaminants
  • Minimizes waste 20-2,000x over membranes
  • Low operating expenses


  • May require chemical addition on low concentrations
  • Limited on short chain and carboxylate removal
  • Requires a large footprint


Case Studies:

FOAM-X™ Pilot Project in Alaska

At the Fairbanks International Airport (FAI), a fire training pit collected PFAS-impacted water from historical firefighting training activities that used AFFF. The water contained elevated levels of PFAS, in which ECT2 partnered with Aquagga for their Surface Active Foam Fractionation destruction technology to achieve waste minimization goals. Read this blog post to learn about our approach to the project and how we collaborated with Aquagga to ensure a project that achieved the client’s goals.


FOAM-X™ System

In this animated video, you can see how our foam fractionation (FOAM-X™) technology is able to remediate PFAS impacted water effectively and economically. This system works well for the removal of both long-and-short chain PFAS compounds, and the foamate is then treated using ECT2’s SuperLoading™ technology or sent offsite for destruction.
