Of the treatments available for PFCs removal from water, adsorption is extensively used given its simplicity, relatively lower cost and high selectivity. Studied adsorbents range from activated carbon (AC), minerals, magnetic nanoparticles, polymers, resins, functionalized cellulose and metal-organic frameworks (MOFs). However, except for MOFs, most adsorbents only exhibit between low and moderate PFOA uptake compared to the industrial standard of AC (>90% removal, 3M Company, USA). MOFs refer to a novel class of porous materials made from organic bridging linkers and metal atoms. Distinguishing MOF features include their high surface areas, ready structure tunability and reusability via simple washing procedures which means that these materials are seen as a promising future substitute for AC. Further to that, in commercial water purification processes, adsorbents are generally deployed into a packed bed for continuous filtration. Fluids flowing through some packed beds may at times result in high pressure drops. This directly increases the energy requirement to pump the fluid through the bed and decreases the operational lifetime of the pumps, impacting on the economics of the process. Although various factors are involved in optimal bed design, lowering the pressure drop can be easily achieved by increasing the adsorbent particle size. Larger particles also facilitate easier recovery in between the washing cycles.
