Abstract

Slaughterhouse wastewater contains a high load of organic and inorganic pollutants, particularly Chemical Oxygen Demand (COD) and Ammonia (NH₃-N), which can cause severe environmental pollution if discharged untreated. A promising biological treatment technology is the Moving Bed Biofilm Reactor (MBBR) with an intermittent aeration system, utilizing pumice stone as a biofilm carrier for microbial growth.This study aims to evaluate the effectiveness of the Moving Bed Biofilm Reactor (MBBR) operated under an intermittent aeration system using pumice stone media in reducing Chemical Oxygen Demand (COD) and Ammonia (NH₃-N) in slaughterhouse wastewater. The variations tested included media filling ratios (25%, 35%, and 45%) and hydraulic retention times (4, 6, and 8 hours) with a balanced oxic-anoxic cycle. The results indicated that increasing the media ratio and retention time significantly improved pollutant removal efficiency. The best performance was achieved at a 45% media ratio with an 8-hour retention time, resulting in COD removal of up to 87% and ammonia removal of up to 82.8%. These findings suggest that pumice stone provides an optimal biofilm surface area to support nitrification–denitrification processes and enhance organic degradation. Therefore, the intermittent MBBR system with pumice stone media offers an effective, economical, and environmentally friendly alternative for slaughterhouse wastewater treatment.
