Advancing Water Purification Solutions for a Resilient America

Water reuse is gaining support as a local, resilient solution. Wastewater recycling conserves resources by substituting treated effluent for potable sources in non-potable uses like irrigation and industrial processes. A key obstacle is the potential health risks from chemical contaminants that persist through treatment and pathogens that could evade disinfection. Recent contaminants of concern include pharmaceuticals, personal care product chemicals, and Per- and polyfluoroalkyl substances (PFAS). Conventional water treatment methods have limitations in removing emerging contaminants and can have high operational costs and environmental impacts. While advanced technologies address more contaminants, they are energy-intensive and expensive providing limited options to address the current challenge of increasing accessibility to freshwater supplies. Pure Spun Innovations (PSI) is proposing a new methodology and technology to address the problem of water contamination by PFAS via an efficient and effective phase-change system. PSI’s novel phase-change water/fluid purification technology uses a NASA-validated vapor compression distillation (VCD) unit, uniquely coupled with parallel concentric rotary-boilers/condensers. VCD systems and are scalable from portable hand-carried purifiers up to industrial sized configurations to fulfill a critical unmet need in wastewater PFAS removal.
