Zusammenfassung:The effectiveness of water hyacinth (EichhorniaCrassipes) in the remediation of municipal wastewater and production of bioethanol was compared with water lettuce (Pistia Stratiotes) and water spinach (Ipomoea Aquatica). Preliminary test using hydroponic system was conducted in order to measure the parameters required at the laboratory scale continuous experimental rig configuration (hydraulic retention time and flowrate). The experiment using the experimental rig was conducted for 18 d for each of the aquatic plant. Water lettuce showed a better removal performance compared with water hyacinth and water spinach. Water lettuce was able to remove 92% of nitrogen and 87% of phosphorus. The production of biofuel was estimated based on known theories. Due to the low concentration of sugar, water spinach managed to produce only 0.10 [+ or -] 0.02 g/g bioethanol. Water lettuce showed better performance in comparison with water hyacinth in the remediation of wastewater and subsequent production of biofuel.
