Abstract: A MBR system for removing PFAS from a flow of wastewater and/or landfill leachate includes an MBR which receives the flow of wastewater and/or landfill leachate having PFAS therein. An impregnation subsystem receives a flow of mixed liquor from the MBR and a predetermined amount PAC to maintain a predetermined ratio of PAC to biomass in the MBR and blends the biomass with the PAC to form PAC-impregnated biological flocs. An outlet coupled to impregnation subsystem outputs a flow of PAC-impregnated biological flocs to the MBR such that the PAC-impregnated biological flocs in the MBR adsorb to and remove a majority of the PFAS from the flow of wastewater and/or landfill leachate and the MBR outputs a flow of treated wastewater and/or landfill leachate having a majority of the PFAS removed.

Abstract: A system for removing carbon dioxide from a flow of gas having carbon dioxide therein is featured. The system includes a first venturi eductor and first reactor which receive the flow of gas having carbon dioxide therein and a flow of a first alkaline solution at a first predetermined pH range. The first venturi eductor and reactor mix and provide reaction time for the flow of gas having carbon dioxide therein and the flow of the first alkaline solution to induce a reaction of the carbon dioxide with the first alkaline solution to form a solution having metal bicarbonate therein. A second venturi eductor and reactor mix the flow of the partially treated gas with the flow of the second alkaline solution and provide reaction time to react a majority of the remaining carbon dioxide with the second alkaline solution to form a solution having metal carbonate therein.

Abstract: A system for removing carbon dioxide from flow of gas having carbon dioxide including a venturi eductor configured to receive the flow of gas having carbon dioxide therein and a flow of an alkaline solution at a predetermined pH range. The venturi eductor is configured to introduce and mix the flow of gas having carbon dioxide therein into the flow of the alkaline solution to induce the transfer of the carbon dioxide into a carbonic acid solution and the subsequent conversion of the carbonic acid solution into a solution having metal carbonate therein. A reactor is coupled to the venturi eductor includes a volume of the alkaline solution and is configured to provide sufficient reaction time to augment the transfer of carbon dioxide into the carbonic acid solution and the subsequent conversion of the carbonic acid solution into a solution having metal carbonate therein and output a flow of treated gas having a majority of the carbon dioxide removed. A pump coupled to the reactor is configured to recycle the flow of alkaline solution from the reactor to the venturi eductor such that the venturi eductor introduces and mixes the flow of gas with the flow of the alkaline solution. An output is coupled to the reactor and is configured to output a flow of a solution having metal carbonate therein to minimize the formation of metal carbonate precipitate in the reactor. A pH adjustment subsystem is configured to maintain the pH of alkaline solution at the predetermined pH range.
