ABSTRACT
This chapter summarizes the role of phytoremediation in the
remediation of industrial waste water since this waste water has
become a treat to water quality. Several technologies are available to
remediate water that is contaminated by industrial pollutant. However,
many of these technologies are costly (e.g. excavation of contaminated
material and chemical/physical treatment) or do not achieve a longterm
nor aesthetic solution. Phytoremediation can provide a costeffective,
long-lasting and aesthetic solution for remediation of
contaminated sites. In many cases, especially in tropical or subtropical
areas, invasive plants such as the water hyacinth (Eichhornia
crassipes) and water lettuce (P. stratiotes L.) are used in these phytoremediation water
systems. This is because, compared to native plants, these invasive plants show a much
higher nutrient removal efficiency with their high nutrient uptake capacity, fast growth rate,
and big biomass production. In the active growth season, for instance, water hyacinth plants
can double in number and biomass in 6 to 15 days. This study shows the important of
phytoremediation in the phytoremediation of industrial waste.
