The primary objective was to evaluate the efficacy of pineapple peel biosorbents in reducing Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), and turbidity in the lagoon's effluent, thereby aligning with the discharge standards set by the National Environment Management Authority (NEMA). The methodology encompassed the preparation of the biosorbents through chemical activation using sodium hydroxide to enhance their adsorptive properties. Subsequent experimental treatments involved the application of these biosorbents to the lagoon effluent at various dosages, followed by rigorous physico-chemical analysis to quantify reductions in BOD, TSS, and turbidity. The study systematically determined the optimal dosage of biosorbents necessary to achieve compliance with environmental discharge standards. Findings from the research demonstrated significant reductions in all targeted effluent parameters, with the optimal biosorbent dosage identified at 250 mg/L. This dosage effectively reduced BOD, TSS, and turbidity levels to within NEMA's regulatory limits, showcasing the pineapple peel biosorbents' potential as a viable alternative to conventional wastewater treatment methods. The study further highlights the dual benefits of this approach: mitigating environmental pollution and repurposing agricultural waste, thus contributing to the circular economy. The implications of this research are far-reaching, offering a scalable, environmentally friendly solution to wastewater management challenges in Uganda and similar contexts worldwide. It bridges the gap between agricultural waste management and environmental engineering, providing a template for future innovations in sustainable wastewater treatment.en-USProject report
