The performance of two types of local floating aquatic plants i.e. water hyacinth (Eichhomia crassipes) and water convulvulus (Ipomea aquatica) in treating domestic wastewater were studied in a small laboratory-scale experiment with a detention time of 5 days. Although both plants showed the ability to remove organic and inorganic pollutants, the average percent removal of water hyacinth was greater than that of water convolvulus for all parameters (BOD5, COD, Fe, Mg, Cu). This difference in removal performance may be due to the difference in the length of the plant roots.
