Abstract
The aim of this study was to investigate the effect of flowing the industrial wastewater effluents into the K lake which is located in the A city on the eutrophication. The lake was modelled as a continuous stirred-tank reactor. Phosphorus and Chl-a concentration in the lake were calculated to $0.29\;/m^3$$4.0\;g/m^3$ at steady state, respectively. Those simulated concentrations were very close to the monitored mean concentration of the lake, indicating that the simulation could be used a tool for characterizing the lake. The non-steady state concentrations of the phosphorus and Chl-a were proposed as a function of time as well. Phosphorus loading ($L_p$) and depth to retention time ratio ($H/{\tau}w$) was calculated in order to analyze the current state of eutrophication. We proposed a strategy to change the lake from eutrophic to permissible oligotrophic state using a graph consisting of two variables, $L_p$ and $H/{\tau}w$.
