Hybrid Closed-Loop Infrastructure Architecture for PFAS Capture, Concentration, Reduction, and Destruction The regulatory and economic framework surrounding PFAS remediation is increasingly misaligned with the scale and urgency of global groundwater and industrial contamination. Existing remediation systems remain dependent on high-cost media replacement, landfill sequestration, long-distance hazardous transport, and high-temperature thermal destruction. This proposal outlines a hybrid closed-loop PFAS remediation infrastructure platform designed to: • Intercept contaminant plumes before watershed expansion • Concentrate dilute PFAS streams into economically manageable treatment volumes • Reduce PFAS mass burden through advanced biological and bioelectrochemical pathways incorporating 2025-2026 synthetic consortia demonstrating >93% PFOS reduction improved destruction confidence • Minimize dependence on thermal destruction • Reduce long-term remediation costs and energy intensity • Support scalable deployment across municipal, military, and industrial environments The system combines: 1. Subsurface plume interception via permeable reactive barriers (PRBs) 2. Selective PFAS concentration systems (foam fractionation + advanced adsorbents) 3. Sealed ex-situ treatment modules with hybrid bioelectrochemical reduction 4. Adaptive biological reduction using Acidimicrobium sp. A6 + high-performance synthetic consortia (GENIA framework and synergistic strains) 5. Electrochemical polishing with BDD, Magnéli-phase Ti4 O7, and integrated BES for synergistic mineralization 6. Continuous telemetry, metagenomic verification, and AI-driven optimization Rather than positioning remediation as a one-time technology sale, the platform operates as distributed environmental infrastructure under a Water-as-a-Service (WaaS) operating model. Enhanced 2026 version integrates latest bioagent discoveries and hybrid BES technology for superior kinetics, lower OpEx, and higher destruction certainty.
