3. INTRODUCTION
• Phytoremediation takes the advantage of the unique and selective uptake
capabilities of plant root systems, together with the translocation,
bioaccumulation, and contaminant degradation abilities of the entire plant
body for the remediation process.
• Using green plants to reduce environmental problems without the need to
dig off the contaminant material and dispose of elsewhere.
• It is an effective remediation method at a variety of sites and on number of
contaminants.
• This technology is environmental friendly and potentially cost effective.

5. OBJECTIVE
• To reduce BOD & COD of wastewater.

The characteristics of influent wastewater observed were as
follows-

8. Selection of plant
Plant species are selected for use based on factors such as:
• Ability to extract or degrade the contaminants of concern
• Availability of plants
• Adaptation to local climates
• High biomass
• Deep root structure
• Compatibility with water
• Growth rate
• Ease of planting and maintenance
Based on above criteria Duckweed and Water Hyacinth
were selected

14. Testing of treated Wastewater
Following tests were carried out on the wastewater after 1 day, 2 day, 5 day and
8 day-
• Chemical Oxygen Demand (COD)
• Biochemical Oxygen Demand (BOD)
• Chloride Content
• Total Dissolved Solids

21. Conclusion
• From the results, it can be seen that if 2 plant density is used for 6 liters of
diluted wastewater sample, then after 2 days unusual results are observed
• In between plant density 4 & 5, not much variation is observed, both having
almost same efficiency in treating wastewater
• If 8 plants density is used for 6 liters of diluted wastewater sample, there is
no appreciable change in results as compared to plants 4 & 5
• Hence it can be concluded that 2 numbers of plant density can be used to
treat wastewater effectively with optimum HRT of 2 days.
21

22. Future Scope
• Further studies on plant can help to improve this technology, so as to become
emerging technology to replace conventional methods.
• The technology can be used in rural areas to treat wastewater without construction of
treatment plant.
• If the effluent discharge of particular Industrial Sewage producing less concentrated
waste, they can easily treat using phytoremediation without constructing Effluent
Treatment Plant (ETP).
