Abstract

An analysis is presented of nutrient absorption controlled by a simple growth law in an artificial wetland system. The distribution of transit times for fluid particles to pass through the wetland is described by a function determined from experimental dye data, and the model includes a constant diffusion term, which is important at slow flow rates. The nutrient absorption efficiency is determined as a function of the flow rate and size of the system. Conditions for maximum absorption are derived from the model for a fixed rate of nutrient input to the wetland using an assumption of nonoverlapping paths. Diffusion within the wetland tends to decrease the absorption efficiency, but this effect may be negligible, provided that the optimum flow rate lies well above a certain minimum value, which is derived from the analysis.
