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. Psis 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. The psis system will substantially reduce or eliminate PFAS into the environment through wastewater effluent. This will prevent further contamination of surface waters, groundwater, soils, and accumulation up the food chain. Wastewater treatment plants will also be able to comply with any regulatory limits on PFAS in effluent that are set in the future. Downstream drinking water sources that currently receive wastewater discharges will be safeguarded from PFAS contamination as the PSI system will remove the chemicals. PFAS treatment and capture will support the circular economy by preventing RE-entry into environmental systems. Psis highly effective treatment could also enable reuse of reclaimed wastewater for nonpotable or indirect potable purposes by reducing concerns over PFAS exposure. Successful completion of phase i is critical to demonstrate a technical pathway for cost-effective commercialization. Once these technical challenges are demonstrated using low-cost materials as proposed by PSI, a technology critical path will be established for straightforward phase 2 manufacturing methods and procedures to produce a new low-cost, high-performance purifier, paving the way as an enabling technology with a large-scale marketing focus to provide a solution that provides: (i) reduced economic losses: (II) environmental protection; and (III) improved human health.
