Efficient PFAS removal from urban wastewater using a novel two-step approach

该项目旨在通过对标准废水处理厂进行两项简单的修改，提高城市废水中全氟烷基和多氟烷基物质（PFAS）化合物的去除率。磁铁矿纳米颗粒将被添加到处理过程中，吸附PFAS化合物并将其降低到可接受的环境水平。所产生的污泥将在一个简单而新颖的自我维持的阴燃过程中干燥和灰化，这将使捕获的PFAS成为适合于现有销毁技术的小灰、冷凝物和气流。预计该项目将支持供水公司实现可持续的水处理，并为社区带来环境和社会效益。

This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining smoldering process which will render the captured PFAS to small ash, condensate and gaseous streams suitable for established destruction technologies. The project is expected to provide support to water utilities in achieving sustainable water treatment and result in environmental and social benefits to the community.
