Abstract: In one embodiment, a system of PFAS (Per-Poly-fluorinated alkyl substances) effluent liquid treatment includes: a pump to pump a liquid received via an intake; a sediment filter to filter sediment from the liquid; a granular activated carbon (GAC) device, disposed downstream of the sediment filter, to remove organic contaminants from the liquid; one (preferably two) or more ion exchange resin columns, disposed downstream of the GAC device, to remove PFAS constituents from the liquid; and a plurality of control valves being controlled to direct the liquid to flow along one or more liquid flow paths through the ion exchange resin columns so as to adjust a rate of processing the liquid by the one or more ion exchange resin columns. The system is disposed in a shipping container to be transported to a destination and is set up in the container onsite at the destination.

Abstract: A composition of five parts by mass of chitosan and one part graphene oxide is suspended in water. The composition may be used to form filtration layers of any size or shape and may be reinforced by additional layers. The composition may be used to construct a large filtration apparatus of any size or shape and may be used to form highly resilient, antimicrobial structures and surfaces for a variety of applications.

Directing the flow takes into consideration factors including any minimum rate of processing, any maximum amount of waste generation, and any target remaining PFAS contamination in the liquid after processing.

Abstract: The present invention includes methods and a system for treating a mass of contaminated media using ammonia. The methods include determining the amount of ammonia required for treatment using various calculation methods and combining the ammonia with air or another carrier gas to create a gas mixture. The methods and system utilize at least one injection well inserted into the contaminated media to deliver the gas mixture over a period ranging from approximately 1 week to approximately 8 weeks.

Abstract: Modifications to the extracellular polymeric substance, predominantly extracellular polysaccharide, of a biopolymer produced by Rhizobium tropici ATCC 49672 yield a stable dry salt transported more easily than a fluid or gel and more stable than either. The salt may be re-constituted with water on-site. Embodiments may be employed as a soil amendment for soil strengthening, reducing hydraulic conductivity, erosion control and dust control as well as a metal chelator for contaminant remediation. Based on comparison with dextran standards, an embodiment demonstrated a molecular weight over 511,000 D. Embodiments include a day salt that is precipitated from solution and in use is re-hydrated back to original form. When added to a sandy soil at 0.1% by dry weight, an embodiment decreased the hydraulic conductivity by three orders of magnitude.
