The study is carried out for removal of nutrients from soil with the help of hydrophytes. Hydrophytes are one of the cheaper and best options for regenerating eutrophic lake. Model eutrophic aquatic ecosystems was designed for bioremediation purpose, for use of hydrophytes, a freshwater static model ecosystem was established. Glass aquarium measuring 180 x 45x 45 cm was used as an ecosystem chamber. Fifteen kg of black soil from Wadali Lake was added to make a 4 cm bed in the aquarium. Different hydrophytic plants like ecchornia, pistia, chara, vallisneria, hydrilla, naja were introduced in the aquarium. Then it was filled with 200 L of water. Afterwards certain species of zooplankton and phytoplankton, snails, Chironomous larvae, Rasbora fishes were introduced in the aquarium. Soil sample was analyzed for one month at five days interval. In a simulated experimental eutrophic model aquatic ecosystem, the nutrients like phosphates, sulphates and nitrates were reduced significantly.
