The global problem of eutrophication, the enrich-ment of water bodies by nutrients, has in recent years resulted in an increased interest in non-conventional ways to reduce the amount of nutri-ents discharged into the environment. One com-monly proposed and used solution is to append constructed wetlands as a final step in the treat-ment of wastewater. However, both the construc-tion of the wetlands and the maintenance thereof are time and resource consuming. Due to the high production and maintenance costs, tools for mod-eling and simulation are often valuable assets in the development of constructed wetlands. In this paper, two ecological models of nitrogen processes in treatment wetlands have been evalu-ated and compared. These models were imple-mented, simulated, and visualized in the Modelica language . The differences and similarities be-tween the MathModelica Model Editor and three ecological modeling tools have also been evalu-ated.
