Figure 5

Comparison of the forecasting values and the measured values for Zn. This figure shows the different prediction results for Zn of the settings of the best model parameters in each model algorithm, indicating the concentration of Zn changes within 2 years’ measurement. The red represents the situation with inputs: Fe, flow, pH, NO3–N, and EC, the green represents the situation with inputs: Fe and NO3–N, and the yellow represents the situation with inputs: Fe.
