Abstract
<title>Abstract</title> <p> Constructed wetlands (CWs) have gained significant attention as a sustainable wastewater treatment solution because of their durability and natural ability to remove pollutants. This established approach offers notable benefits when integrated with microbial fuel cells (MFCs), as it harnesses the metabolic processes of anaerobic microbes in CWs to generate electrical power. This research examined the pollutant removal efficiency of constructed wetland coupled microbial fuel cells (CWMs) using <italic>Canna</italic> , <italic>Typha</italic> , and <italic>Eichhornia</italic> plants. Five lab-scaled CWM systems with vertical flow and identical design parameters were built and then evaluated for their effectiveness in removing physicochemical parameters and heavy metals. The CWM’s systems utilize a graphite rod (cathode) and a carbon fiber sheet (anode) for electrode configuration. The study spanned 24 days, with wastewater samples analysed at regular 3-day intervals to assess variations in physicochemical properties. The CWM with <italic>Typha</italic> plant species achieved reductions of 93.28% in total dissolved Salts, 95.14% in biological oxygen demand, 88.05% in chemical oxygen demand, 96.75% in phosphate, and 82.27% in nitrate. The CW-MFC with <italic>Typha</italic> plant species produced the highest current and voltage, measuring 1.08 mA and 0.157 V, respectively. The findings demonstrated that <italic>Typha</italic> into CWMs can improve electrokinetic processes, offering a scalable solution for effective textile wastewater treatment coupled and bioelectricity generation. </p>
