Engineering360: "How electro-oxidation is redefining PFAS destruction"

Electro-oxidation (EO) is an advanced water treatment technology that uses electricity to break down persistent pollutants like PFAS (“forever chemicals”) into harmless substances such as CO₂ and fluoride. Unlike traditional methods that only capture contaminants, EO can completely destroy them, making it a more effective and sustainable solution.

PU flooring and Epoxy flooring are not directly involved in PFAS destruction, but they can be used in EO or water treatment facilities:

• Epoxy flooring: Highly chemical-resistant and durable, ideal for heavy-duty industrial environments
• PU flooring: Flexible, anti-slip, and resistant to temperature changes—suitable for wet and hygienic areas

�� So, PU and Epoxy flooring can be easily integrated into EO-based treatment plants to ensure a strong, safe, and long-lasting working surface.

Electro-oxidation: A potential method for destruction of PFAS The electro-oxidation process aims at treating PFAS rather than just transferring the pollution to a different waste stream. This differentiates the process from PFAS treatment by adsorption (e.g., activated carbon or ion-exchange resin) in which the PFAS are captured on the media with the focus being on effectively managing or regenerating the media used.

The electrochemical process involves application of an electrical potential for reaction to occur at an electrode. This can lead to attack of PFAS molecules if the right conditions are set in terms of the water chemistry, electrode material and design and operating conditions (current density, mass transfer rate and competition with other organic and inorganic species), energy input and electrode stability.

In real wastewater, electro-oxidation is therefore usually combined with other steps for concentrates of PFAS (or wastewaters) to show complete mineralization of the PFAS and evaluate reduction of transformation products rather than simply achieving a certain percentage reduction in PFAS.
