In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment. Membrane filtration processes play important roles in the treatment of reclaimed municipal wastewater. However, there is very limited knowledge regarding the reliability of such processes in removing trace contaminants from recycled water, which may result in unintended health consequences. This research will lead to a comprehensive understanding of the removal process of such contaminants by membrane filtration. Consequently, the likely avenue of risk can be eliminated and the treatment process can be optimised to achieve economic savings and environmental protection.

在澳大利亚，水循环被认为是管理目前持续缺水和更好地保护环境的主要措施。膜过滤技术在城市污水再生处理中占有重要地位。然而，关于这种工艺在从再循环水中去除痕量污染物方面的可靠性的知识非常有限，这可能导致意想不到的健康后果。该研究将有助于对膜过滤去除此类污染物的过程有一个全面的了解。因此，可以消除可能的风险途径，并优化处理过程，以实现经济节约和环境保护。
