Utilizing the broad electromagnetic spectrum and unique nanoscale properties for chemical-free water treatment
(Elsevier, 2021) Westerhoff, Paul; Alvarez, Pedro J.J.; Kim, Jaehong; Li, Qilin; Alabastri, Alessandro; Halas, Naomi J.; Villagran, Dino; Zimmerman, Julie; Wong, Michael S.; Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment (NEWT)
Clean water is critical for drinking, industrial processes, and aquatic organisms. Existing water treatment and infrastructure are chemically intensive and based on nearly century-old technologies that fail to meet modern large and decentralized communities. The next-generation of water processes can transition from outdated technologies by utilizing nanomaterials to harness energy from across the electromagnetic spectrum, enabling electrified and solar-based technologies. The last decade was marked by tremendous improvements in nanomaterial design, synthesis, characterization, and assessment of material properties. Realizing the benefits of these advances requires placing greater attention on embedding nanomaterials onto and into surfaces within reactors and applying external energy sources. This will allow nanomaterial-based processes to replace Victorian-aged, chemical intensive water treatment technologies.
