To ensure environmental protection, wastewater must be treated before being released into the environment. This study focuses on enhancing the quality of industrial effluent using natural zeolites. Samples were obtained from the Biyinzika poultry slaughterhouse and subjected to testing. Initial tests revealed significantly high levels of Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), turbidity, Total Nitrogen (TN), and Total Phosphorus (TP) compared to national standards, indicating the need for secondary treatment in addition to the existing wastewater treatment system due to the high organic content of the effluent.
The primary goal and design of this research were achieved, which involved implementing a secondary treatment system with zeolites following the initial treatment processes to ensure the effluent meets required standards before discharge. The use of natural zeolites improved treatment efficiency, resulting in substantial reductions in turbidity, BOD, COD, TN, and TP by 75.7%, 81.3%, 90.8%, 64.2%, and 89%, respectively. These reductions ensured that all parameters met the required discharge standards, confirming the successful completion of the research objectives.
