As the different parts of Lotus plant (Nelumbo nucifera) are used for various purposes in pharmaceutical industries, even some of its parts are edible too. Is it suitable to find its potential of removing heavy metals from industrial wastewater.
There is a report showing that Lotus has the potential for phyto-remediation.
Lotus has been evaluated for remediation of trace elements focusing on manganese ( Mn ), organic compounds targeting s- metalachlor and filtering aquaculture wastewater. Lotus was also evaluated for filtering trace elements by establishing a base line for tissue composition and evaluating lotus capacity to grow in solutions with high levels of elements and found no visible signs of toxicity. From these studies Lotus proved to be an effective phyto- remediator. For more details consult Evaluation of Sacred Lotus as an Alternative Crop for Phyto - remediation. etd.auburn.edu

Yes , very much. Lotus is a perennial aquatic plant which has a thick rhizome besides roots. While the plant assist in bioremediation of dissolved contaminants, the flowers has a aesthetic value and and hence marketed .
Dear Piyush,
Generally its not better if you use the edible plants for phytoremediation. Even not for cattle feed. Because in such case, the heavy metal remaining in the ecosystem. Its always recommended to use such kind of plants those you can use later for bio-energy production. Maybe some aquatic plants with high biomass could helps in this case. After accumulation of heavy metals, you could use them for energy production in combustion plant and separate the heavy metals from the ashes.
Hello, it is highly recommended because it has rhizomes, which is usually related to the hyperaccumulation of heavy metals. However, you mention that for industrial water, so I recommend you first evaluate the content of heavy metals qualitatively and quantitatively, as well as corroborate that the water contains K, N and P.
Another aspect that makes a plant species relevant for removing heavy metals is that they have had a natural adaptation, for example, in the vicinity of mining industries or polluted rivers. This is because they will surely contain rhizospheric bacteria adapted to heavy metals and will create a synergism in the removal of these.
Greetings and I hope you will benefit from the above mentioned personal experience.
