Macromolecular Fouling in Membrane Bioreactors

随着澳大利亚和海外对生活和工业用水需求的增加，膜生物反应器（MBR）提供了一种与传统工艺相比产生更高出水质量废水的替代方案。然而，用于去除污垢沉积物（这会降低操作性能）的曝气成本需要进一步最小化。该提案旨在通过使用多糖、蛋白质和微生物细胞的模型系统，并将其与实际MBR系统进行比较，研究涉及污染物组分沉积的基本机制。鼓泡不同气体成分（空气/H2S比）的影响，本研究将研究一种防止或去除MBR系统中污染物的新方法。

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.
