While reduction of particulate forms of phosphorus (P) from point and non-point sources can be achieved with minimal cost and technology, removing dissolved P remains a challenge. Countless studies spanning over two decades have identified many P sorption materials (PSMs), including several by-products, that are effective at removing dissolved P from solution. Several materials have shown promise in the laboratory, yet scaling up to flowing conditions in the field remains a challenge when considering feasibility and economics. The aim of this Special Issue is to present recent advances and challenges in removing dissolved P at the field-scale with P removal structures. Field studies are preferred, but laboratory experiments are welcome if they specifically address challenges related to field implementation of P removal structures. Experiments solely focused on characterizing PSMs and P sorption isotherms, however, will not be considered for inclusion in this Special Issue. Regarding flow-through experiments conducted at any scale, changes in P loads rather than P concentrations alone must be presented. Studies must also provide information regarding the economics of P removal structure implementation at the field-scale; assessments that only evaluate PSM cost at the field- scale will not be considered. Current challenges in scaling up to field-scale P removal structures include (but are not limited to): 1) achieving a high flow rate while maintaining sufficient P removal; 2) efficiently removing dissolved P from sources with relatively low dissolved P concentrations (i.e. < 0.2 mg/L); 3) re-generating PSMs in-situ; 4) constructing structures on sites with little to no hydraulic head; 5) clogging of media; 6) lack of trained professionals in design and construction of P removal structures; and 7) maintaining low costs in construction and maintenance.

Abstract: The reduction of dissolved phosphorus (P) transport to water systems remains of critical importance for water quality. P sorption materials (PSMs), active media with high affinity for dissolved P, are the core components of P removal structures, a novel technology able to intercept dissolved P in surface and subsurface flows, before they reach water systems. While the P removal ability of PSMs has been extensively studied, lesser is known about the capacity to regenerate and recover P from P-saturated PSMs. This article evaluates a methodology to recover the P removal ability of P-saturated PSMs. A KOH treatment is being suggested to regenerate aluminum- and iron-rich PSMs, aiming to increase their lifetime in P removal structures. A series of flow-through experiments was conducted alternating between P sorption (0.5 and 50 mg L−1 P) and desorption with KOH (5 or 20 pore volumes), varying residence times (0.5 min and 10 min) and number of recirculations (0, 6 and 24). Across two cycles of sorption-desorption, Alcan, Biomax and PhosRedeem showed an average P recovery of 81%, 79% and 7%, respectively. The comparative investigation of the tested treatments revealed that the most effective regeneration treatment is characterized by a larger KOH volume (20 pore volumes) and no recirculation, with up to 100% reported P recovery. Although the smaller KOH volume (5 pore volumes) was less effective, the use of recirculation did increase P recovery. From this study, we conclude that the use of Biomax and Alcan in P removal structures can be extended through the demonstrated regeneration techniques in both high and low P concentration scenarios.
