The presence of toxic organic compounds in water supplies is of great environmental concern in Canada and around the world. The majority of these contaminants can be destroyed completely by photo-initiated oxidation (activation of strong oxidants such as hydrogen peroxide by ultraviolet -UV- radiation to form oxidative hydroxyl radicals) or photocatalytic oxidation (formation of hydroxyl radicals through photocatalytic reactions). Despite considerable research and commercial interests in UV photo-initiated and photocatalytic oxidation processes in the past few years, little is known about the process simulation and optimization of these technologies. As a result, their industrial application to water treatment has been limited and commercial systems, in general, have met with only partial success.

在加拿大和世界各地，供水中有毒有机化合物的存在是一个重大的环境问题。 这些污染物中的大多数可以通过光引发的氧化（通过紫外线-UV-辐射活化强氧化剂如过氧化氢以形成氧化性羟基自由基）或光催化氧化（通过光催化反应形成羟基自由基）完全破坏。尽管在过去的几年中，紫外光引发和光催化氧化过程中的相当大的研究和商业利益，很少有人知道这些技术的过程模拟和优化。 因此，它们在水处理方面的工业应用受到限制，商业系统一般只取得部分成功。
