The Past, Present and Future of Phosphorus Removal Structures

This resource explores the current challenges of Phosphorus Removal Structures and develops 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.
