  • Publication number: 20210322951
    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 ion exchange resin columns. 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.

  • Patent number: 11052351
    Abstract: The present invention is directed to rigid filtration apparatus comprising a filter support and filter membrane. Such filter support is comprised of a central core. Radiating from the central core are a plurality of pleats composed of two angled walls terminating at a contact point. Such longitudinal walls circumscribe a longitudinal channel situated between the walls wherein the longitudinal channel is in communication with the central core. The longitudinal walls are comprised of a plurality of openings along the walls. A filter membrane having biocidal components may be utilized with the filter support to effectively treat contaminated fluid, gas or air. Alternatively, the composition of the rigid central core and the rigid pleats may be composed of different materials to selectively remove chemicals, biological components or pharmaceuticals in a multi-stage treatment process.

  • Patent number: 9511399
    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.
