ELECTROCHEMICAL DESTRUCTION OF PERFLUORO COMPOUNDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240043292 titled 'ELECTROCHEMICAL DESTRUCTION OF PERFLUORO COMPOUNDS

Simplified Explanation

The abstract describes an assembly, system, and method for electrochemical destruction of perfluoro compounds, such as PFOS, PFNA, and PFOA, or other oxidizable or reducible compounds. The method involves flowing an aqueous liquid containing a perfluoro compound into a vessel that houses a bipolar electrode assembly. The bipolar electrode assembly consists of a first electrode stack and a second electrode stack, with the first stack having a plurality of electrodes and the second stack having another plurality of electrodes. The electrodes span laterally across at least a portion of the vessel and define the boundaries of a tortuous path through the vessel. The aqueous liquid is then flowed through the vessel via the tortuous path, while a voltage is applied to the bipolar electrode assembly, effectively destroying the perfluoro compound.

  • The invention is an assembly, system, and method for electrochemical destruction of perfluoro compounds or other oxidizable/reducible compounds.
  • The assembly includes a vessel housing a bipolar electrode assembly.
  • The bipolar electrode assembly consists of a first electrode stack and a second electrode stack.
  • The first electrode stack has a plurality of electrodes, and the second electrode stack has another plurality of electrodes.
  • The electrodes span laterally across at least a portion of the vessel, defining a tortuous path through the vessel.
  • The method involves flowing an aqueous liquid containing a perfluoro compound into the vessel.
  • The aqueous liquid is then flowed through the vessel via the tortuous path.
  • A voltage is applied to the bipolar electrode assembly while the aqueous liquid flows through the tortuous path.
  • The applied voltage destroys the perfluoro compound, effectively eliminating it.

Potential Applications

  • Treatment and removal of perfluoro compounds, such as PFOS, PFNA, and PFOA, from aqueous solutions.
  • Remediation of contaminated water sources, such as industrial wastewater or firefighting foam runoff.
  • Environmental cleanup of areas affected by perfluoro compound contamination.
  • Water treatment in industries where perfluoro compounds are used or produced, such as semiconductor manufacturing or textile industries.

Problems Solved

  • Perfluoro compounds are persistent and difficult to degrade, posing environmental and health risks.
  • Conventional treatment methods for perfluoro compounds are often expensive, energy-intensive, or inefficient.
  • The electrochemical destruction method provides a more effective and efficient solution for eliminating perfluoro compounds from aqueous solutions.

Benefits

  • Efficient and effective destruction of perfluoro compounds, reducing their environmental and health impacts.
  • Lower cost and energy requirements compared to conventional treatment methods.
  • Scalable and adaptable for various water treatment applications.
  • Provides a sustainable solution for remediation and cleanup of perfluoro compound-contaminated sites.
