Application of anaerobic membrane bioreactor is strictly limited by the membrane fouling because of the fouling prone nature of the feed. This study evaluates a method to enhance the effectiveness of a bubbling system for fouling control in filtration of anaerobic digestion sludge treating palm oil mill effluent using a tilted panel system. Such system is expected to enhance the role of biogas recirculation as the bubbling fluid for membrane fouling control. Effect of tilting angle, bubbling rate, intermittent bubbling period, and panel switching period was investigated. The energy consumption for applying such system was also estimated. Results show that the tilted panel with bubbling remarkably enhance permeability by more than double of the vertical system to reach a maximum value of 87 Lm⁻²h⁻¹bar⁻¹, the highest value reported so far. The panel switching mechanism helps to enhance the system throughput by allowing two-sided membrane panel with intermittently bubbling, in the expense of mechanical switching energy. The estimation of energy consumption of the system has been estimated at 0.247 kWhm⁻³, corresponding to 0.3 % of total electricity generated from anaerobic treatment of POME, very attractive for full-scale implementation.

厌氧膜生物反应器的应用受到膜结垢的严格限制，因为进料易于结垢。这项研究评估了一种方法，该方法可提高使用倾斜面板系统过滤处理冒泡系统的效率，该方法可用于污垢控制厌氧消化污泥处理棕榈油厂废水的过滤。预期这种系统将增强沼气再循环作为起泡流体以控制膜污染的作用。研究了倾角，起泡率，间歇起泡周期和面板切换周期的影响。还估计了应用这种系统的能耗。结果表明，起泡的倾斜面板显着提高了渗透性，是垂直系统的两倍以上，达到最大值87 Lm ^-2 h ^-1bar ^-1，是迄今为止报告的最大值。面板切换机制通过使双面薄膜面板间歇性鼓泡来帮助提高系统吞吐量，但以机械切换能量为代价。该系统的能耗估计为0.247 kWhm ^-3，相当于POME厌氧处理产生的总电力的0.3％，对于全面实施非常有吸引力。
