METHOD OF ELIMINATION OF POLY- AND PERFLUOROALKYL SUBSTANCES (PFAS) IN A WASTEWATER BIOSOLIDS GASIFICATION PROCESS USING A THERMAL OXIDIZER AND HYDRATED LIME INJECTION
An 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. Synthesis gas (syngas) exits the gasifier which is coupled to a thermal oxidizer and is combusted at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat can be recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger that is coupled with the thermal oxidizer. Cooled flue gas is mixed with hydrated lime, enhancing PFAS decomposition, with the spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements. The apparatus and methods thereby eliminate PFAS from wastewater biosolids and control emissions in the resulting flue gas.
BIOPOWERPLANT: THIRD GENERATION BIOREFINERY WITH IMPROVED CAPACITY TO USE DOMESTIC WASTEWATER, LANDFILL LEACHATE AND SEA SALT WATER AS AN INPUT TO GENERATE GREEN ENERGY, WATER FOR REUSE, BIOFUEL, ORGANIC FERTILIZERS AND CAPTURE ATMOSPHERIC CO2
The Biopowerplant is a system that integrates the generation of carbon-neutral energy through the cultivation and conversion of microalgal biomass, with sewage sanitation and environmental carbon recovery, with the additional and secondary production of biofertilizer, biofuel, water for reuse. This system integrates a suboptimal anaerobic digestion subsystem focused on the generation of biogas, the processing of the resulting digestate through a microalgal consortium culture subsystem with biofilm induction and smooth decreasing gradient of light radiation, and the transformation of the generated microalgal biomass into syngas through a subsystem of evaporation, torrefaction, pyrolysis, gasification, and combustion in separate chambers. The syngas and methane from the biogas are subsequently used as fuel in an electric power generator capable of operating with mixed gases. The biogas generation process is enriched through the recirculation of the microalgal biomass supernatant, the residual heat from the syngas generation subsystem, and the heat transferred from the combustion gases of the electric generator. The residual sludge from the biogas generation subsystem is recirculated towards a longitudinal biopile subsystem, where it acts as an anaerobic medium compared to the aerobic medium that constitutes the concentrated microalgal biomass, and both streams are mixed to be transformed into the syngas generation subsystem. Input inflows for system operation are mainly sewage, and optionally seawater and/or leachate. The inflows must be bioaugmented with a microalgal consortium dosed automatically by a Compact in situ bioaugmentation system, preferably more than 3 kilometers before the inflow enters the system.
