Algae concentration prediction models under controlled initial conditions in microcosm environment

To achieve more accurate algae concentration prediction models for satisfying with the needs of water bodies with different nutrients' characteristics, the algae prediction models were modified by introducing related correction factors under controlled initial conditions in the microcosm environment. Results showed that the prediction model was more precise by introducing total nitrogen(TN) as the correction factor when the ratio of nitrogen to phosphorus was 5:1, while the model was more accurate by introducing total phosphorus(TP) when the ratio of nitrogen to phosphorus was 15:1 and 25:1. The algae concentration prediction models under controlled initial conditions in the microcosm environment were helpful to predict algae concentration accurately for water plants.
