Molecular Fluorine-Carbon Bonds in PFAS have been successfully broken in our lab making Fluorite and Calcium Fluoride and Carbonate solid by-products in our two stage process. Electrically Charged Vibrating Graphite Disc Electrodes generate the required 140 kcal / mol. of energy at points of contact with waterborne PFAS particles needed to break Fluorine-Carbon molecular bonds. ( USPTO provisional filing date granted )

Under development is our scalable 100 Gal / Hr. pilot system comprising our Electrolysis Reactor Modules and our subsequent Calcium Hydroxide Neutralizer / Fuel Cell stage where we reclaim electrical power and the solids by-products.

All Inquiries are welcome. Complete Engineering shop drawings and specs will be available for manufacture with license.

Stage 1; PFAS & Carbon Electrode Fluorine Interface

Piezo-Electric applied vibration to Carbon Electrodes brings the applied surface energy to the PFAS particles to a minimum of 140 kcal / mol on contact with the carbon negative electrode.

It was found that vibratory energy was needed to generate a response in the production of hydrogen fluoride which is the chemical marker that carbon fluorine cleavage has occurred in the Teflon tape ( PFAS ) test sample surface.

Sensorex HF-10 Sensor response to Hydrogen Fluoride from Teflon tape (PFAS) wound around graphite disc electrode perimeter..

First successful test making hydrogen fluoride from Teflon tape, indicating C-F bond cleavage between carbon and fluorine.
One will notice the voltage on the meter “bumping up” in increments of millivolts, where 4 mV = 1 ppm of hydrogen fluoride.

A prior version (right) used graphite rod electrodes and higher voltages with negative results. It was found greater surface area and acoustic vibration significantly improved reactivity with the water. The Hydrogen Fluoride response from the Teflon tape (PFAS) was observed up to 10 ppm with the graphite discs acoustically driven by piezo-electric elements.

It makes little sense streaming away the H + OH radicals taking energy to make from the water electrolysis in order to neutralize a few ppm of PFAS in the subject water.

The system will be economically viable energy wise configured as shown here with recovery of electrical energy expended in the water electrolysis..

In conjunction with neutralizing the HF acid and Carbonic acid generated in the first stage reaction with the carbon electrodes, the concentration of hydroxide electrolyte is adequate to allow a fuel cell function.

Our hydroxide based fuel cell recovers the electrical energy spent in making OH + H radicals from the water electrolysis and stores that energy in conventional lead acid auto batteries.
