Abstract :

<p>&nbsp;Increasing of urbanization, industrialization and over population are leading causatives of environmental pollution.&nbsp;</p> <div>Small and medium scale industries in Tamil Nadu playing a major role in polluting water bodies and key among&nbsp;</div> <div>pollutants are suspended solids, biological oxygen demand and heavy metals contamination. Conventional methods&nbsp;</div> <div>of treatment such as chemical precipitation does not provide sustainable solutions as the pollutants are merely transferred from the waste&nbsp;</div> <div>water to a sludge residue which is disposed of by land&ndash;filling. The pollutants eventually find their way to contaminating freshwater supplies.&nbsp;</div> <div>Phytoremediation, an eco&ndash;friendly technology which is ecologically sound and economically viable; it is also an attractive alternative to the&nbsp;</div> <div>current cleanup methods that are very expensive. This technology involves efficient use of aquatic plants to remove, detoxify or immobilize heavy&nbsp;</div> <div>metals from waste water.&nbsp;</div>
