The disinfection of municipal drinking-water supplies and treatment of waste-water by exposure to high-power ultraviolet (UV) light is now a practical alternative to chlorination. UV light can kill or sterilize the micro-organisms that pose a health hazard through highly selective photo-biological reactions that disrupt the microbial DNA. The aim of this project is to research and develop new 'germicidal' UV light sources based on Barrier Discharge lamps, operating in novel excitation regimes, to yield high UV efficiency. Successful demonstration of the technology will provide solutions to the growing economic and environmental challenges relating to water conservation within Australia.

城市饮用水供应的消毒和高功率紫外线（UV）照射处理废水现在是氯化的一种实际替代方法。紫外线可以通过高度选择性的光生物反应，破坏微生物的DNA，杀死或消灭对健康造成危害的微生物。该项目的目的是研究和开发基于阻隔放电灯的新型“杀菌”紫外线光源，在新的激发机制下运行，以产生高紫外线效率。该技术的成功演示将为澳大利亚日益增长的与水资源保护有关的经济和环境挑战提供解决方案。
