| Abstract | The challenges of climate change, increased greenhouse gas emissions, water pollution,and environmental quality degradation have intensified the necessities for ecologicalsustainability, lower operating expenses, and nature-based solutions. The aquatic plant; Azollais highly suggested to apply in bioremediation process as an ecological treatment method.The present study aimed to investigate the potential of Azolla microphylla in intergrading thephytoremediation of domestic wastewater treatment, biomass growth for biological carboncapturing, and its nutrient content for generating valuable by-products. The experiment wasconducted by using a completely randomized design with four treatments. After the experimentalperiod, the highest reduction of biological oxygen demand (BOD) 75.9% and chemical oxygendemand (COD) 72.9% were observed in domestic wastewater (DW). The highest nutrientremoval of nitrate nitrogen (NO3-) 46.5% and orthophosphate (PO43-) 62.5% was observed inDW. The reduction in the concentration of treatments were significant compared to controlsat a significance level of p < 0.05. The maximum carbon sequestration rate of 1.36 g CO2 perg of dry weight for Azolla was observed in DW. This study was conducted to optimize thepotential of A. microphylla in promoting the Bio-Circular-Green economy model, that aims toutilize renewable biological resources and transform into valuable by-products, to contributein water pollution management, to eliminate atmospheric carbon dioxide, to keep a balanceamong the economy, society, and environment. |
