Wastewater has a high content of nutrients, such as phosphorus, nitrogen, and organic matter can cause environmental problems in water bodies, if not treated efficiently. The use of Constructed Wetlands (CW’s) as a wastewater treatment method has been expanding, given the need to reduce operating costs and use more sustainable treatment methods. CW’s in addition to wastewater treatment also promote other functions, such as the conservation of biodiversity and its habitats, the regulation of the climate, the hydrological cycle and public use. Hybrid beds were born out of the need to improve treatment efficiency and consist in the conjugation of several individual treatment types into one system. CW’s reduce the impact of human activity on wastewater. This paper presents a review of the diversity of existing wetted beds.
