Abstract: Apparatus and methods to eliminate PFAS from wastewater biosolids through fluidized bed gasification. The gasifier decomposes the PFAS in the biosolids at temperatures of 900-1800° F. Syngas exits the gasifier which is coupled to a thermal oxidizer and combusts at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat is recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger coupled with the thermal oxidizer. Various methods inject moisture into the gas stream, controlling temperature through evaporative cooling and/or injecting chemicals that react with gas stream components. Cooled flue gas mixes with hydrated lime capturing decomposed PFAS molecules with spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements, eliminating PFAS from wastewater biosolids and controlling emissions in the resulting flue gas.
