Abstract
Phytoremediation is a novel, efficient, ecofriendly, low priced and an emerging method of biotechnology for environmental pollution management. In this technology, plants are used to improve the status of environment. In this work, an attempt has been made to remove organic and inorganic pollution load of domestic wastewater. A culture of aquatic plant, Lemna minor was grown in the pond water. Water from the same pond was filled in a cement tank and Lemna was grown for a stipulated interval of seven days. The domestic wastewater quality was evaluated before and after the culture by analysing its physicochemical properties in order to know the improvement in quality of water. The results of analysis show that phytoremediation of wastewater occurs more rapidly in tank water as compared to the pond water. The increase in biomass of Lemna minor and the physicochemical analysis have proved that Lemna minor is a suitable aquatic plant for phytoremediation of domestic wastewater, which improved the quality of domestic wastewater by absorbing organic and inorganic pollutants.
