NanoSORB™ Membrane Bioreactor

ECT2’s research and development team have been testing various ways to remove PFAS utilizing existing filtration systems. The NanoSORB™ enmeshment process ensures the additive remains with the biological solids and does not separate or settle out in the activated sludge process. This technology works well with highly contaminated and difficult to treat wastes such as landfill leachate, in municipal and industrial wastewater, and for applications requiring low effluent PFAS, nutrients, chemical oxygen demand (COD), total organic carbon (TOC), and more.


  • Provides removal to a wide range of contaminants to low levels, including PFAS, recalcitrant compounds, and biodegradable organics
  • Faster kinetics which reduces tankage needs and footprint
  • Leverages high surface area and extended contact times, allowing for greater removal of PFAS, TOC, COD, and other contaminants of concern, resulting in more efficient use of media
  • Provides benefit of biological and adsorptive treatment mechanisms in a single process


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.
