New Tech Filters PFAS 100x Faster
23 Jan
Summary
- New filtration technology absorbs PFAS 100 times faster than current systems.
- Researchers developed a method to destroy PFAS without high temperatures.
- The new material can be repeatedly used and integrated into existing infrastructure.
A significant advancement in combating PFAS contamination has emerged from Rice University, where researchers have engineered a novel material capable of absorbing these persistent "forever chemicals" up to 100 times faster than conventional systems. This innovative layered double hydroxide (LDH) material, enhanced with copper and aluminum, offers a promising solution for accelerating water pollution control and remediation processes.
Beyond rapid absorption, the research also details a groundbreaking method for the destruction of PFAS without resorting to high temperatures. This non-thermal process concentrates the chemicals within the LDH material, allowing for their breakdown at relatively low temperatures of 400-500°C. The byproduct, calcium-fluoride, is stable and safe for landfill disposal, addressing a critical challenge in the complete elimination of these harmful compounds.
Experts note that while industrial-scale deployment remains a challenge, the material's efficiency, reusability, and compatibility with existing filtration infrastructure significantly reduce cost barriers. This development could mark a turning point in the global effort to mitigate the widespread environmental and health risks associated with PFAS exposure.
