As the demands for domestic and industrial water increasing in Australia and overseas, membrane bioreactors (MBR) offer an alternative for producing higher effluent quality wastewater compared to conventional processes. However, aeration costs used to remove fouling deposits (which reduce the operating performance) need to be further minimised. The proposal aims to study fundamental mechanisms involve in the deposition of foulant components by using model systems of polysaccharides, proteins and microbial cells and comparing these with real MBR systems. The effect of bubbling varied gas compositions (air/H2S ratios) a novel approach in this study will be investigated to prevent or remove foulants in MBR systems.

随着澳大利亚和海外对生活和工业用水需求的增加，与传统工艺相比，膜生物反应器（MBR）提供了一种生产更高出水质量废水的替代方案。然而，用于去除污垢沉积物（其降低操作性能）的曝气成本需要进一步最小化。该提案的目的是通过使用多糖，蛋白质和微生物细胞的模型系统，并与真实的MBR系统进行比较，研究涉及污垢成分的沉积的基本机制。鼓泡不同的气体成分（空气/H2S的比例）的影响，在这项研究中的一种新的方法将被调查，以防止或去除膜生物反应器系统的污垢。
