This comparative study of domestic wastewater treatment using natural systems like artificial wetlands shows organic matter (BOD5) removal rates between 70% and 86% using water hyacinth and of 58% using common duckweed. The artificial wetland system behaves hydraulically as a piston-flow model regardless of the aquatic plant used. During the experiment, it was observed that common duckweed contributes characteristic elements to water that increase the effluent's pH (> 11), whereas water hyacinth elevates the pH value in the range of 6-8, thus favoring the stabilization of the organic matter within the biological system.
