The presence of heavy metal in river water due to the disposal of industrial waste in that water, this causes the environmental effects and leads to the health issues. Various modern equipment and natural methods are available to remove the heavy metals in polluted water, the methods available to remove heavy metals are such as chemical precipitation, ion exchange, reverse osmosis, membrane filtration, bio absorption and phytoremediation. The objective of the study is to evaluate the phytoremediation capability of water hyacinth (Eichhornia Crassipes). The people from the study area faces water shortage due to poor water quality issues for their daily needs. Therefore, attempts were made to treat the water present in the Amaravati River near by dye industry, Under the 7 days of operation period, water hyacinth showed the maximum removal efficiency in the pH, BOD, COD, TDS, Chromium and Lead. The novelty of the present study is to use water hyacinth (Eichhornia Crassipes) for treating the industrial effluent (heavy metals accumulated) with the variation in combination of phytoremediation such as 10% and 20% were used for treatment and found that optimum percentage is 20% of water hyacinth. The research findings reveal that the use of Eichhornia Crassipes technique in treatment of Dye waste water is an economical way.
