Disposal of waste products and residuals into the natural water bodies can have
fatal consequences for aquatic ecosystems, posing severe threats to natural
habitats and human health. Natural treatment systems are the most suitable
treatment technologies for various types of wastewaters, which has attracted much
attention in recent years. Phytoremediation is a plant-based technique used to
eliminate or recover surplus nutrients in contaminated environments. The use of
aquatic plants in wastewater phytoremediation is very efficient due to they have a
very significant ability for assimilating and degrading contaminants (e.g., nitrates,
phosphates, and heavy metals). Phytoremediation is a relatively new technology
that is considered as an operational, efficient, new, and environmentally friendly
technology that is still in the early stages of development and optimization. Its
application on a large scale is still limited. It should also be noted that a clear vision
of this innovation should be taken into account and, accurate data should be made
available to the public as it will enhance its efficiency as a manageable solution in
the worldwide. Additionally, phytoremediation has been evaluated as a separate
low-tech and environmentally friendly green option compared to the existing
technologies. The present study attempts to review the recently published literature
to explain phytoremediation technology and its advantages in purifying water and
