Ultraviolet (UV) irradiation has emerged in the past few years as one of the best water purification alternatives. The ultraviolet light emitting diode (UV-LED) is a new technology that has recently experienced rapid improvements and new possible applications. These advances create the opportunity for the development of novel LED-based water purifiers. In fact, UV-LEDs could potentially revolutionize water treatment systems by replacing traditional UV mercury lamps.***In the proposed research program, we plan to discover how certain unique features of UV-LEDs can be utilized to significantly improve water purification. We will study the fundamentals of UV-LEDs for water treatment and their application in the development of novel UV-LED reactors. We will further investigate the impact of several unique characteristics of UV-LEDs, which are likely to result in much more efficient methods of water purification. Furthermore, we will simulate, optimize, and design original UV-LED reactors that offer the precise control of both the fluidic and optical environments to achieve superior reactor performance. Finally, we will fabricate and operate UV-LED reactor prototypes to identify the capabilities and limitations of this emerging technology for water purification as well as its potential for applications where UV reactors have never before been used.***The principal investigator has over fifteen years of experience in the development of UV reactors for water treatment in both the industry and in academia. He has initiated and established a strong research program at UBC that focuses on the development of UV reactors for water purification in collaboration with industrial partners.***We expect this research to result in the development of the next generation of UV reactors with high efficiency and special features that are currently unavailable in UV-lamp reactors and other incumbent technologies. The students trained during this program will be highly qualified to lead world-class research and development activities in the Canadian water and environmental industries. Canada is a world leader in the development of UV water purification reactors, and Canadian companies play a significant role in marketing UV-based water treatment systems. As a result, we are in an excellent position to exploit and benefit from this technology and from the training of highly qualified researchers in this field.***This research program applies an emerging technological opportunity to an important social issue. Growing concern over the waterborne diseases in numerous remote and small communities has driven demand for new water treatment systems to meet their special needs. The proposed research program plans to address this demand by advancing the field of UV-based water purification through the development of efficient and compact UV-LED reactors, which will operate at low power and are practically maintenance-free.**

紫外线（UV）照射在过去几年中已成为最好的水净化替代品之一。紫外发光二极管（UV-LED）是一种新技术，最近经历了快速的改进和新的可能的应用。这些进步为新型LED净水器的开发创造了机会。事实上，UV-LED可能通过取代传统的紫外线汞灯来彻底改变水处理系统。在拟议的研究计划中，我们计划发现如何利用UV-LED的某些独特功能来显着改善水净化。我们将研究用于水处理的UV-LED的基本原理及其在新型UV-LED反应器开发中的应用。我们将进一步研究UV-LED的几个独特特性的影响，这些特性可能会导致更有效的水净化方法。此外，我们将模拟，优化和设计原始的UV-LED反应器，提供流体和光学环境的精确控制，以实现上级反应器性能。最后，我们将制造和操作UV-LED反应器原型，以确定这种新兴技术用于水净化的能力和局限性，以及其在紫外线反应器从未使用过的应用中的潜力。首席研究员在工业和学术界开发用于水处理的UV反应器方面拥有超过15年的经验。他在UBC发起并建立了一个强大的研究计划，专注于与工业合作伙伴合作开发用于水净化的UV反应器。我们希望这项研究能够开发出下一代具有高效率和特殊功能的紫外线反应器，这些功能目前在紫外线灯反应器和其他现有技术中无法使用。在该项目期间接受培训的学生将完全有资格领导加拿大水和环境行业的世界级研发活动。加拿大在紫外线水净化反应器的开发方面处于世界领先地位，加拿大公司在销售紫外线水处理系统方面发挥着重要作用。因此，我们处于一个非常有利的位置，可以利用这项技术并从中受益，并从该领域高素质研究人员的培训中受益。该研究计划将新兴技术应用于一个重要的社会问题。对许多偏远和小型社区水传播疾病的日益关注推动了对新水处理系统的需求，以满足他们的特殊需求。拟议的研究计划计划通过开发高效紧凑的UV-LED反应器来推进基于紫外线的水净化领域，以满足这一需求，该反应器将在低功率下运行，几乎无需维护。
