Abstract
Artificial wetlands are relevant for wastewater treatment and are effective in removing nutrients such as nitrogen through the activity of bacteria, protozoa and fungi. In this research, an experimental horizontal subsurface flow wetland located at the Universidad Michoacana de San Nicolás de Hidalgo (UMSNH) was used, built with compact gravel and using Typha domingensis as vegetation, which receives wastewater from the Centro de Información, Arte y Cultura (CIAC). It was observed that the plants remove 77.28% of the total nitrogen in the initial stage, 69.78% in the intermediate stage and 77.37% in the adult stage, indicating an effective capacity for the removal of this organic pollutant, which allows us to conclude that the implementation of this system in wastewater treatment is viable.
