Bibliometric Analysis of Constructed Wetlands with Ornamental Flowering Plants: The Importance of Green Technology

The use of constructed wetlands (CWs) for wastewater treatment has earned high interest around the world. However, innovations to improve its removal efficiency and adoption have been suggested in last decades. For instance, ornamental flowering plants (OFP), which make wetland systems more aesthetic is an option production commercial flowers while water cleansed. objectives this study were identify through a bibliometric analysis (2000–2022) main OFP that used CWs their functionality as phytoremediators (removal effects), well authors, collaborations, investigations, countries where such investigations carried out. To respect, 10,254 studies on identified. United States China leading eco-technology. Subsequently, regarding OFP, revealed 92 matter Mexico three researchers who lead (almost 40% publications with OFP), species studied include Canna hybrids, Zantedeschia aethiopica, Strelitzia reginae, Iris species, Spathiphyllum sp., Anturium sp. These may remove between 30–90% pollutants organic compounds, 30–70% heavy metals drugs, about 99.9% pathogens. Thus, help new design, know future research directionsand collaboration approaches area using multipurpose alternatives like those OFP. More can still be out temperate climates, evaluating influence different substrates flow growth these plants.
