PFAS Filtration Systems for Industrial & Municipal Water Treatment
Emerging Contaminants (PFAS, Chromium 6, 1,2,3 TCP & more.)
Yardney Free Flow Water & Waste Water Filtration Systems
Ideal for remediation applications requiring reliable and effective mitigation in drinking water, waste water and ground water treatment applications.
Yardney Granular Activated Carbon (GAC), IX resin and specialty media filtration systems are engineered for highefficiency removal of PFAS, Iron, Manganese, Arsenic, other emerging contaminates and suspended solids. These advanced media filtration systems combine the adsorption capabilities of Granular Activated Carbon (GAC) with the selective removal performance of Ion Exchange (IX) resin and specialty medias can be customer tailored site specifically with unlimited flow rate capability. The filtration systems are designed to target a broad spectrum of PFAS compounds, including both short-chain and long-chain variants, emerging contaminants and suspended solids. The systems can be utilized as GAC, IX resin or a dual media design (One vessel GAC, One vessel IX resin), allowing for optimized performance based on site-specific water quality parameters and water treatment

CFD (Computational Fluid Dynamics) Models
Simulation of the flow of water through a media bed-specifically, modeling laminar flow through a Granular Activated Carbon (GAC) or Ion-Exchange (IX) Resin Bed. A less turbulent model, shown in blue is indicative of a higher effective flow rate through a vessel preventing channeling, improving effectiveness of the filtration media and reducing pressure differential across the vessel.
