Abstract

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.
