ABSTRACT
This study aims to analyze the performance of the Oxic–Anoxic process in a Moving Bed Biofilm Reactor (MBBR) system for reducing Chemical Oxygen Demand (COD), Total Nitrogen (TN), and Ammonia (NH3-N) in slaughterhouse wastewater. The treatment was conducted using a batch system with variations in bioball media filling ratios of 15%, 25%, and 35%, and hydraulic retention times of 2, 3, and 4 hours. The results showed that increasing the media volume and retention time improved pollutant removal efficiency. The highest removal efficiency was achieved at a 35% media filling ratio and 4-hour retention time, with reductions of 71.22% for COD, 87.47% for Total Nitrogen, and 90.71% for Ammonia (NH3-N). The oxic–anoxic process effectively supported the nitrification–denitrification mechanism in decomposing nitrogen compounds and organic matter. The MBBR technology proved to be efficient, easy to operate, and has strong potential for application in slaughterhouse wastewater treatment.
Keywords: Denitrification, Nitrification, Oxic-Anoxic, MBBR.
