Abstract

The objective of this study was to develop a modified simplest seasonal model that predicts phosphorus removal efficiency for lakes using marsh wetland system using lake waters. The proposed model calculates the wetland removal efficiency and total outflow phosphorus (TP(out)) concentration as a function of the soluble and nonsoluble reactive phosphorus (SRP and NSRP respectively) while considering the accumulation mechanisms. The observed and predicted TP(out) concentrations compared reasonably which suggest that empirical models can be adapted to estimate the phosphorus removal efficiency of the marsh wetlands. The results also indicate that TP(out) concentrations decreased exponentially with time through the wetland and decreasing the surface hydraulic loading rate of the system would increase the removal efficiency of phosphorus. It was observed that about 78% of the total phosphorus and 77% of the soluble phosphorus content within the water column was removed with about 19% of the total phosphorus removed within the first 5 days (13% of the system detention time).
