This research aims to investigate landfill leachate treatment using a submerged-type membrane bioreactor (MBR) with varying intermittent aeration times of 120-120 and 150-150 minutes. The objective is to assess the removal efficiencies of chemical oxygen demand (COD), color, total Kjeldahl nitrogen (TKN), and total phosphorus (Total P). A series of experimental runs were conducted to evaluate the performance of a BPAC-MBR system, which integrates activated carbon to enhance treatment efficiency. The results indicated that the BPAC-MBR with an intermittent aeration time of 150-150 minutes achieved the highest removal efficiencies of 83% for COD, 85% for color, 97% for TKN, and 68% for Total P. This method demonstrated improved substrate removal compared to single MBR systems. The extended duration of intermittent aeration allowed microorganisms to effectively treat readily biodegradable influent COD while reducing soluble inert COD through sequential aerobic and anaerobic periods. Overall, the study highlights the significance of aeration time in optimizing leachate treatment processes and suggests that longer durations can enhance efficiency in removing harmful substances from landfill leachate.
