The wastewater treatments with ﬂoating macrophytes have proven eﬀective in the remediation of waters with nutrient content, organic matter and toxic substances such as arsenic, zinc, cadmium, copper, lead, chromium, and mercury. Its importance lies in its ability to be used in rural communities due to their low consumption of conventional energy and practicality in the assembly and operation of treatment systems. Still, it has not been clariﬁed thoroughly the processes taking place in the puriﬁcation of wastewater with ﬂoating macrophytes. This article attempts to review the existing literature on ﬂoating macrophytes, thus identifying the general aspects, advantages and disadvantages of using these plants for treating wastewater. Similarly, identify the most important background since the beginning of this application. There will be described models and design criteria mostly employed, rigorously reviewing removal eﬃciencies of diﬀerent species of ﬂoating macrophytes. Finally it will be addressed as discussed current perspectives and future challenges for the development of this technique.
