The study investigates the utilization of cow dung-based bioreactors for the degradation of organic pollutants in wastewater, a pressing environmental concern. Given the persistent nature of these pollutants and their harmful impacts on aquatic ecosystems and human health, innovative and sustainable treatment methods are urgently needed. This research focused on evaluating the effectiveness, environmental sustainability, and economic viability of cow dung-based bioreactors, comparing their performance against conventional wastewater treatment methods and control samples without cow dung. Through a series of experiments involving the measurement of pollutant concentrations before and after treatment, the study demonstrated that cow dung-based bioreactors significantly enhance the degradation of organic pollutants. The findings reveal not only improved efficiency in pollutant reduction but also highlight the potential environmental benefits, including a lower chemical footprint and enhanced sustainability, and economic advantages of using cow dung as a treatment agent. Despite the promising results, the study also identifies scalability as a potential challenge, suggesting avenues for future research. The implications of this research extend to the fields of environmental engineering and sustainable wastewater management, offering a cost-effective and environmentally friendly alternative to traditional treatment methods.
