The increasing challenge of municipal sewage water management necessitates innovative and sustainable solutions. This study investigates the potential of aquatic weeds in treating sewage water from Vellalore, a municipality facing significant water pollution issues. Aquatic weeds, known for their rapid growth and high bioaccumulation capabilities, offer an eco-friendly alternative to conventional sewage treatment methods. In this study, various species of aquatic weeds were utilized to treat sewage water through a series of controlled experiments. Parameters such as chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS), and heavy metal concentrations were measured before and after treatment to evaluate the efficacy of the aquatic weeds. The results demonstrated a substantial reduction in COD, BOD, and TSS, indicating the effectiveness of aquatic weeds in purifying sewage water. Furthermore, significant removal of heavy metals was observed, showcasing the phytoremediation potential of these plants. The study also explored the optimal conditions for maximizing the treatment efficiency, including plant species selection, density, and treatment duration.
