Interpretive Summary: This brief article presents a summary of the history of P removal structures, where the technology currently stands, summarizes the studies in the special issue of Water dedicated to P removal structures, and the future of P removal structures. A future research direction is given.

Technical Abstract: The purpose of this special issue is to explore current challenges and develop a better understanding of the processes that control dissolved phosphorus (P) removal among P removal structures. By exploring limitations and grasping the details of P removal processes by P sorption materials (PSMs) at a large scale we can begin to develop solutions and create more feasible, effective, and economical P removal structures. The most difficult challenges at the field scale are issues associated with flow rate; specifically, premature clogging, the need to operate at flow rates high enough to treat large flow events that deliver the majority of the dissolved P, and achieving such flow rates while also ensuring proper retention time (RT) for dissolved P removal.
