Abstract: Plasma/cell concentrator apparatus and methods are described herein for concentrating constituents from a fluid. Generally, a volume of the fluid may be urged from a first reservoir to a second reservoir through a fluid channel and a volume of desiccant for mixing with the fluid may be introduced to create a mixture.

Abstract: A process for PFAS decontamination comprises exposing water comprising PFAS contaminant to gas to accumulate a PFAS concentrate and separating the PFAS concentrate. PFAS separation is enhanced by the addition of a hydrofluorocarbon refrigerant, such as 1,1,1,2 tetraflouroethane, difluoromethane or pentaflouroethane to the gas wherein it is believed that with carbon-fluorine bonds of the hydrofluorocarbon refrigerant aid in attracting the carbon fluorine tail of all types of PFAS compounds to the water-gas interface and especially aids separation of smaller molecular weight PFAS molecules, including beyond what can be achieved using charged or ionised gases alone, thereby allowing a larger spectrum of PFAS molecules to be extracted from soil or water.

Abstract: Various embodiments relate to a filtration system. The filtration system includes a housing having a drain. A filter element is positioned within the housing. The filter element comprises a first endplate and a second endplate. Filter media is positioned between the first endplate and second endplate. A dual lip seal member is coupled to the second endplate. The dual lip seal member includes a first protrusion that extends radially outward around an outer surface of the dual lip seal member. A second protrusion extends radially outward around the outer surface of the dual lip seal member. The dual lip seal member is configured to prevent fluid to be filtered from exiting the housing through the drain when the filter element is in an installed position. The dual lip seal member permits residual fluid to exit the housing through the drain when the filter element is displaced from the installed position.

Abstract: A septic tank filter system includes a tank. The tank includes an inlet and an outlet, wherein the outlet is disposed on the tank below the inlet to enable a flow of wastewater to be gravity fed from the inlet to the outlet. A filter is positioned in the tank. The filter includes a frame. A filter media is disposed on the frame.
