Abstract: A method and system for removing non-aqueous phase liquids (NAPL) from geologic media below the surface of the ground, employing a flexible liner disposed down a borehole. A flexible carrier liner has an absorbent outer cover composed of a NAPL-absorbent outer layer and a NAPL-absorbent inner layer, both preferably hydrophobic. The liner with outer cover is placed down the borehole, preferably but not necessarily by eversion. Liner placement presses the absorbent outer layer against the borehole wall. NAPL in the groundwater adjacent the outer layer is absorbed into the outer layer and then wicked into the inner layer. The liner and outer cover can then be extracted from the borehole to remove from the subsurface the NAPL absorbed in the cover's absorbent layers. If portions of the liner are transparent, a down-hole camera may be deployed to monitor the degree of NAPL absorption in the absorbent inner layer.

Abstract: A two-stage treatment process for destroying per- and polyfluoroalkyl substances (PFAS) in an aqueous stream. The two-stage treatment process uses a combination of multifunctional crystalline molecular sieves, such as zeolites and zeotypes, to separate PFAS from the aqueous stream, catalytically decompose and defluorinate any PFAS molecules, and generate non-toxic waste products that are safe for disposal. The first stage includes adsorption of the PFAS within one of a pair of vessels containing porous, hydrophobic, hydrothermally stable molecular sieves, dehydration of the captured PFAS on the sieves, and catalytic ozonation of the captured PFAS molecules on the dried sieves. The second stage involves catalytic decomposition and neutralization of the ozonation results with one of a pair of vessels including a zeolite-supported CaO catalyst, catalytic oxidation of any toxic CO generated by the decomposition, and an acid wash for regeneration of the spent catalyst.

Abstract: A submersible vessel which can act as a reusable bath bomb delivery system is provided. The vessel may include a housing and an opening port. The interior of the housing and ports form a chamber, which can be segmented into multiple sub-chambers. Inlet one-way valve(s) and outlet one-way valve(s) are provided on the vessel. To use, the chamber is partially filled with a mixture including an effervescent material. When water is introduced through the inlet valve, it reacts with the effervescent material, releasing carbon dioxide and dissolving the other ingredients in the mixture, building pressure in the chamber. When the pressure builds to a certain level, the inlet valve(s) are closed, and the outlet valve(s) are opened. The outlet valves may be positioned such that when the fluid and gas is expelled, the force generated may cause the vessel to spin or be propelled in the bath.

Abstract: A method of removing organic carbon and other contaminants from a water stream. The method comprises screening large solids from the stream. Pre-oxidation chemicals may then be added. A coagulant is fed into the stream. An activated carbon, preferably formed from lignite, is added by pumping a highly concentrated activated carbon slurry into the stream. The stream, including the activated carbon and coagulant, next flows into a clarifier, where the coagulant will flocculate and enmesh the activated carbon. The activated carbon adsorbs organic carbon and other contaminants, including bacteria, pharmacological agents, and hydrocarbons, as the stream flows through the clarifier. Eventually, the flocculate will agglomerate and settle out in the clarifier, where it, the enmeshed carbon, and the contaminants they contain may be removed. The stream's organic carbon content exiting the clarifier will be much reduced. Accordingly, less primary oxidizing agent will be needed to treat any remaining organic carbon.
