Estimating phosphorus removal by steel slag in a flume experiment: effects of phosphorus concentration and subsurface hydrological condition

Excessive phosphorus (P) in water bodies is one of the most concerning water quality issues in the U.S., impacting public health, the environment and the economy. Managing excessive P is essential to reduce the incidence of environmental quality issues, such as eutrophication and harmful algal blooms. One potential strategy that is being developed for this purpose is the use of P sorption materials (PSMs) to sequester P from water systems, which is the objective of this study
