Introduction

Polytetrafluoroethylene (PTFE) is a widely used fluoropolymer belonging to the PFAS (per- and polyfluoroalkyl substances) family. Celebrated for its chemical stability, heat resistance, and non-stick properties, PTFE is found in countless industrial applications, from coatings and membranes to cables and medical devices. However, this same chemical resilience makes PTFE microplastics a significant environmental challenge, as they are extremely difficult to remove once released into water systems [1].

The Challenge of PTFE in Water

Due to PTFE’s unique molecular structure, it is highly resistant to degradation. When PTFE particles enter water sources, whether through industrial effluents, membrane degradation, or product wear, they persist in the environment. Over time, physical and chemical degradation can break these microplastics into even smaller nanoparticles, which are more difficult to detect and remove with conventional filtration methods. This growing presence of PTFE microplastics poses risks to aquatic ecosystems and potentially human health, necessitating advanced solutions for effective separation and removal [2,3].

Conventional Water Treatment Can’t Catch PTFE

Recent studies highlight the complexity of PTFE microplastics in water treatment. Research indicates that standard wastewater treatment processes often fail to capture these persistent particles due to their size and chemical inertness. Degradation processes can even worsen the problem by transforming microplastics into nanoparticles that bypass conventional filters [4].

SGen-I: A Disruptive, Chemical-Free Solution

Our patented SGen-I technology presents a breakthrough, chemical-free method for removing persistent micropollutants from water. Harnessing magnetic force without the use of additives, SGen-I effectively captures PTFE microplastics, PFAS polymers, biopolymers, and other hard-to-treat contaminants. In a recent R&D project, SGen-I achieved a remarkable 99.997% separation efficiency specifically for PTFE,  a major milestone in tackling one of the most resistant forms of microplastic pollution. By stopping the recirculation of these pollutants in industrial water systems, SGen-I extends membrane and filter lifespans, enhances operational efficiency, and supports compliance with tightening PFAS regulations.

Beyond PTFE: A Versatile Water Treatment Technology

While PTFE microplastics exemplify the challenging pollutants SGen-I can target, the technology’s potential extends across various industries, including hydrogen production, semiconductor manufacturing, pharmaceuticals, agriculture, and more. Its chemical-free operation and compact design enable seamless integration into existing water management systems, promoting sustainability and circular water use.

Conclusion

As PTFE and other micropollutants increasingly threaten water quality and industrial processes, innovative technologies like SGen-I are essential for sustainable water management. Our solution not only addresses today’s environmental challenges but also future-proofs water systems for safer, cleaner operations.
