Abstract

The aquaculture industry is among the fastest growing food production sectors in the world. However, due to the world's rapidly increasing population and industrial development, many water resources have become contaminated, resulting in the continuous discharge of organic and inorganic wastes from human activities into natural water bodies. The aquatic ecology is at risk from excessive levels of chemical substances including N2, C2, NH3, PO4, HCO3-, vitamins and medications, which can disrupt the normal food chain. The majority of developing countries have serious concerns about wastewater treatment. Efficient wastewater treatments through conventional methods are expensive and difficult to get optimum results. In recent years, natural treatment systems have gained a lot of interest as the best treatment solutions for different kinds of wastewater. Currently, Phytoremediation is a cost-effective and efficient way to remove harmful contaminants from aquatic environments. The phytoremediation can be used as a different environmentally friendly green alternative to existing techniques. In this study describes various aquatic plants, such as Eichhornia, Duckweed etc. which have high potential to remove pollution from wastewater.
