Efficient wastewater treatment can be achieved in
several ways, physical, chemical and biological.
Phytoremediation is one of the biological wastewater
treatment methods which is simple, environmentally
friendly and consumes less energy. Suitable plant species
used for phytoremediation should have high uptake of
both organic and inorganic pollutants, grow well in
polluted water and be easily controlled in quantitatively
propagated dispersion. Vetiver grass (Vetiveria
zizanioidesrecently reclassified as Chrysopogon
zizanioides) belongs to the gramineae family and was
first used for soil and water conservation purposes.
Due to its unique morphological and physiological
characteristics, and tolerance to high levels of heavy
metal and adverse conditions, vetiver has also been
successfully used in the field of environmental
