Aquaculture wastewater with moderate concentrations of organic pollutants is very suitable for treatment with aquatic plants. The study was conducted with 3 experiments, in which, enydra fluctuans lour and ipomoea aquatica selected for wastewater treatment has an average height of 10 cm, grown in a model (styrofoam box) with a density of 100 trees/m2. The research results showed that ipomoea aquatica and enydra fluctuans lour could adapt and grow well in the eel farming wastewater, which was characterized by an increase in biomass parameters. The ability of ipomoea aquatica to treat organic pollutants is higher than that of enydra fluctuans lour. The results were reached via experiment as follows: The average density and biomass of ipomoea aquatica were increased by 1.32 times and 4.9 times, while the average density and biomass of enydra fluctuans lour were increased by 1.69 times and 4 times, after 20 days of experiment. The pH of wastewater after treatment was ranged from 7 to 8. Total suspended solids (TSS) of wastewater after treatment was reduced by about 78%. COD concentration in the experiment of enydra fluctuans lour was decreased by about 70%, while COD concentration in the experiment of ipomoea aquatica was decreased by about 83%.
