BIOFILTRATION OF HEAVY METALS
Technology: This is an advanced technology developed by Prof. B.D. Tripathi (2007) and used for removal of heavy metals from the wastewater.
Principle: Aquatic plants such as Eichhornia crassipes, Pistia stratiotes, Lemna minor, Azolla pinnata, and Spirodela polyrhiza are used in different combinations to remove the heavy metals.
Removal: >95% removals of the Cr, Cd, Cu, Zn, Fe and Ni have been demonstrated.
Recognition of the Technology: Technology is commonly used for removal of heavy metals. Technology was published in the year 2007 in an International Journal “Ecological Engineering 30(1)9 – 15 (2007)”.
