Abstract: A continuous reactor and method for destroying contaminants, such as perfluoroalkyl and/or polyfluoroalkyl substances in various feedstocks. Liquid byproducts are continuously hydrolyzed in an aqueous alkaline solution to achieve greater than 99.99% destruction of the contaminants. Continuous hydrolysis achieves a greater conversion efficiency as compared to batch reactions and has a wide application of contaminated feedstocks.

Abstract: Apparatus and methods for determining a concentration of one or more halogen-containing ions in a sample, including but not limited to: soils, aquifers, groundwater, drinking water, soil, tissue, blood, sewage sludge, compost, and landfill leachate, Particularly, the apparatus and processes are used for the destruction of per- and polyfluoroalkyl substances (PFAS), per- and polyfluorocarbons (PFCs), pesticides, munitions, 1,4-dioxane, pharmaceuticals, microplastics, and others. High destruction efficiencies of these substances is desirable for determination of compliance with government regulations. Apparatus include batch- and continuous-type reactor systems. Processes include supercritical water oxidation (SCWO) and hydrothermal alkaline treatments (HALT).

Abstract: Disclosed herein are embodiments of a hydrothermal reactor, such as a downflow hydrothermal reactor and methods of using the same. Also disclosed herein are system embodiments comprising the hydrothermal reactor. Method embodiments disclosed herein facilitate determining operation parameters for the hydrothermal reactor that give rise to efficient feedstock conversion to products while maintaining integrity of the reactor (e.g., avoiding corrosion) and providing safe operating conditions. The disclosed reactor and system embodiments facilitate situations where small scale and/or remote destruction of feedstocks (e.g., chemical warfare agents and/or environmental toxins) is needed.
