Role of microorganisms in the remediation of wastewater in floating treatment wetlands: a review - Projects
Updated : October 2020
Constructed wetlands are a recent, sustainable solution to textile wastewater treatment. With increasing demands for more eco-friendly, efficient practices, several research activities are being carried out in this area, to enhance the potential of constructed wetlands.
This review article provides details on floating treatment wetlands (FTW), which is a novel technology, based on a floating vegetated system, that has unique abilities to remediate wastewater. It emphasizes the role of microbes in enhancing the potential of FTWs.
It discusses the mechanism of FTWs, key components, and the major species of bacteria that colonize the plant roots to form biofilms for remediating the textile wastewater. Furthermore, the specific role of rhizospheric bacteria, endophytes, and algae in the pollutant removal process in FTWs have also been elaborated.
The study concludes that bacterial biofilm has a crucial role in the removal of organics, inorganics and metals in FTW systems and that further research is need to better understand the specific microbe and plant interactions and their beneficial role in the pollutant removal process in the textile wastewater systems.
