A new system using artificial aeration in constructed wetlands was tested to improve nitrogen removal from polluted river water. The system achieved a 64.97% removal of total nitrogen, with different components contributing to the removal process. Additionally, the system also removed about 75% of ammonia, with the artificial aeration unit playing a significant role. The concentrations of ammonia and nitrate in the outflow were reduced, showing the system's effectiveness in removing pollutants from wastewater.
