Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water treatment methods are insufficient in removing per- and polyfluoroalkyl substances (PFAS) from solids, liquids, and gases due to their persistence in the environment and toxicity, leading to environmental and health concerns.
Innovation Solution
Generating structurally altered gas molecules with a higher electron attraction probability, which are infused into matter containing PFAS, breaking the C—F bonds and degrading them into non-harmful substances using a system comprising a chemical reaction chamber, magnetic field generator, and electric field to create hydrated electrons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatment methods (activated carbon filtration, ion exchange, advanced oxidation processes) are used, then treatment capacity is maintained, but removal effectiveness of PFAS is insufficient
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional treatment parameters to a plasma-based process that generates hydrated electrons. This fundamental parameter change enables effective PFAS removal while maintaining treatment capacity, resolving the contradiction between removal effectiveness and productivity
Solution Approach 2:
The patent replaces mechanical filtration systems (activated carbon) and chemical processes (ion exchange, advanced oxidation) with a plasma-based electron generation system. This substitution achieves superior PFAS removal effectiveness without sacrificing treatment throughput
2Reliability
If hydrated electrons are generated through plasma process, then PFAS degradation effectiveness is enhanced, but energy consumption increases
Solution Approach 1:
The patent uses hydrated electrons generated through plasma as a powerful reactive species for accelerating PFAS degradation. This approach enhances degradation effectiveness while the plasma process efficiently manages energy input, addressing the energy-con effectiveness tradeoff
3Productivity
If plasma process is used to generate hydrated electrons, then treatment speed increases, but system complexity increases
Solution Approach 1:
The patent employs a plasma process that can be integrated into existing water treatment infrastructure, using gas-phase reactions to generate hydrated electrons that then treat the liquid stream. This approach increases treatment speed while avoiding overly complex system architecture

AI summary
Methods and systems for degradation of polymeric substances is provided. An example method includes generating structurally altered gas molecules from water, where the structurally altered gas molecules have a higher probability of attraction of electrons into areas adjunct to the structurally altered gas molecules than molecules of the water. The method further includes infusing the structurally altered gas molecules into a matter containing the polymeric substances, where upon being infused, the structurally altered gas molecules cause a decrease in concentration of the polymeric substances in the matter.
