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.

该项目旨在通过对标准污水处理厂进行两个简单的修改，加强对城市污水中全氟烷基物质和多氟烷基物质(PFAS)的去除。磁铁纳米颗粒将被添加到处理过程中，它将吸附全氟辛烷磺酸化合物，并将它们降低到可接受的环境水平。产生的污泥将在一种简单而新颖的自持阴燃过程中干燥和灰化，这将使捕获的全氟辛烷磺酸变成适合现有销毁技术的小灰烬、冷凝液和气态流。预计该项目将为水务公司实现可持续的水处理提供支持，并为社会带来环境和社会效益。
