Description: MDFRC item.
Description: The short term capacity for phosphorus in plan led artificial wetlands, and the equilibrium orthophosphate concentration in their effluent are determined by the sorptive potential of the gravel. The long term capacity is determined by the plants, which can have seasonal fluctuations in uptake. The speed of uptake to gravel is diffusion controlled. The major orthophosphate sorption sites are iron, associated with the biofilm. In reducing conditions when Fe (1111) is reduced to Fe (111) the equilibrium orthophosphate concentrations rise greatly. Suggestions for managing constructed wetlands so as 10 sustain maximal phosphorus removal are discussed in a separate confidential report.
