REM
Using Flash Joule Heating to destroy PFAS
ECT has acquired an innovative Rapid Electrothermal Mineralisation (REM) process, a subset of Flash Joule Heating (FJH) developed at Rice University, to destroy PFAS and remove heavy metals within the environment.
The REM Process
Laboratory results have demonstrated over 96% defluorination efficiency and 99.98% removal of perfluorooctanoic acid (PFOA), one of the most common PFAS pollutants.
The REM technology is being developed in response to the absence of scalable, in-situ solutions capable of permanently destroying PFAS.
Advantages of REM Technology
REM aims to provide a fast, energy-efficient, and scalable solution to environmental PFAS contamination issues.
REM and Remediation of PFAS Contamination in Soil
Development of high-frequency / high-power system for direct electrical heating (no use of solvents or reagents to lower costs), both in-situ and ex-situ
Establish commercial partnerships to develop a pilot “remediation tractor” using current farming technology
Scale production of “remediation tractors” by utilizing autonomous driving to remediate contaminated land and reduce personnel costs and remediation time
REM and Remediation of PFAS Contamination in GAC
- The same core technology enables PFAS remediation in both soil and spent Granular Activated Carbon (GAC), creating a seamless, cross-application solution for land and water treatment
- GAC is widely used to adsorb PFAS, primarily in water treatment applications
- Global PFAS water contamination is driving urgent market demand for scalable, verifiable PFAS destruction technologies
- The ability to destroy PFAS-laden GAC on site has the potential to reduce reliance on transport and incineration pathways while minimising secondary waste streams
- In addition to PFAS destruction, the process can transform spent carbon media into higher-value carbon products, including graphene, graphite and other advanced carbon materials
