Light-assisted treatment is one of the most attractive methods for wastewater reclamation - a major issue for Australia with limited fresh water resources. However, commercial exploitation is hindered by inability to harness sunlight and poor photoreactor design. This proposal deals with the development of Co-titania photocatalyst activatable by visible light to effect organic degradation and bacterial sterilization simultaneously at room temperature. The new reactor permits in-situ separation of the solid catalyst from treated liquid thus ensuring continuous production of recyclable water. The huge economic returns of solar-operated mobile or stationary wastewater unit from local and international markets are obvious.

光辅助处理是最有吸引力的废水回收方法之一，这是淡水资源有限的澳大利亚面临的一个主要问题。然而，由于无法利用阳光和光反应器设计不佳，商业开发受到阻碍。本研究旨在开发一种可在室温下以可见光活化的钴-二氧化钛光催化剂，以同时实现有机物的降解和细菌的杀灭。新的反应器允许从处理过的液体中原位分离固体催化剂，从而确保可循环水的连续生产。太阳能操作的移动的或固定的废水处理装置在当地和国际市场上的巨大经济回报是显而易见的。
