Summary:
The presented innovation introduces a “drop-in” treatment apparatus and system designed to efficiently remove per- and polyfluoroalkyl substances (PFAS) from contaminated liquids. This system leverages cost-effective and readily available materials, making it a practical solution for addressing widespread PFAS contamination in wastewater. The apparatus consists of modular cartridges containing mesh containers filled with sorbent or resin materials. These cartridges are connected to a submersible pump via tethers and powered by an external power source, enabling flexible deployment in various contaminated water environments. The sorbents used in the system include pyrogenic carbon, granular activated carbon, biochar, zeolite, aluminosilicates, and their combinations. These materials are selected for their high adsorption capacity and availability. The system's design emphasizes simplicity and adaptability. Its "drop-in" configuration enables rapid installation without extensive infrastructure modifications, making it suitable for both quick response scenarios and long-term remediation efforts. By integrating proven adsorption technologies with an accessible deployment model, this apparatus offers an effective and economical approach to mitigating PFAS contamination in diverse settings. This breakthrough aligns with global efforts to address PFAS pollution, which poses significant environmental and public health risks due to the persistence and toxicity of these compounds. By utilizing inexpensive materials and an easy-to-use design, the innovation provides a scalable solution that can be widely adopted to protect water resources and public health.
