The waste water treatment techniques such as Activated sludge process, Adsorption/bio-oxidation process, Advanced oxidation process, Aerated lagoon, Aerobic granular reactor, Aerobic granular sludge technology and Phytoremediation, are practised in different industries worldwide. In this study Phytoremediation method is applied to study the waste water quality parameters removal efficiency of different plants for treating waste water. The main objective of the study is to find the efficiency of removal of different waste water quality parameters from the synthetic waste water generated in the laboratory by different plants such as Hyacinth, Vetiver, Pharagmites austrilus, and Canna Indica. The waste water quality parameters such as Total hardness, Biological oxygen demand, Dissolved oxygen, Total dissolved solids, Lead, Zinc and Copper are taken in the synthetic waste water samples preparation. After experimental studies using Phytoremediation models, the results arrived are as follows: (1) Hyacinth removal efficiency from Total hardness synthetic solution is 69.28% and from total dissolved solids (TDS) synthetic solution is 3.35% and also it is observed that the Dissolved oxygen(DO) and Biological oxygen demand(BOD) reduction from synthetic solutions prepared . (2) Canna Indica removal efficiency from TDS synthetic solution is 2.63% and also it is observed that the DO and BOD demand reduction from synthetic solutions prepared. (3) Vetiver removal efficiency from TDS synthetic solution is 74.92% and also it is observed that the DO and BOD reduction from synthetic solutions prepared. Vetiver removal efficiency from Zinc, Lead and Copper synthetic solutions are 14.43%, 47.61% and 32.07% respectively. Phragmites austrilus removal efficiency from Zinc, Lead and Copper synthetic solutions are 10.67%, 19.07%, and 23.27% respectively. Since the retention time is less in this study it has come less removal efficiency for different plants. It is observed that the phytoremediation technique is very economical and may be implemented to many industries.
