Development of ultraviolet light emitting diode (UV-LED) reactors for water purification

近年来，紫外线(UV)辐照已成为最好的净水替代品之一，加拿大、美国和欧洲的许多主要城市都采用紫外线作为其主要的消毒工艺。鉴于近年来紫外光发光二极管(UV-LED)性能的提高和成本的降低，紫外光发光二极管(UV-LED)有望取代紫外光汞灯，从而使水处理系统发生革命性的变化。我们将致力于一项全面的研究，以探索UV-LED灭活各种病原体的基础。我们将开发集成的计算模型来模拟性能，并将该模型应用于UV-LED反应器的设计。最后，我们将制造、操作和评估用于净水的UV-LED光反应器。我们的团队在净水用UV反应器的开发和应用方面拥有超过25年的工业界和学术界经验。我们与三家加拿大UV公司建立了强有力的支持和合作伙伴关系，贡献了行业专业知识，并为该技术的商业化提供了一条潜在的途径。我们预计该项目将导致下一代紫外光反应堆的开发，该反应堆有望在项目完成后的短短几年内投放市场。经济利益，可能达到数百万美元，将可能被在全球销售的加拿大紫外线反应堆制造商所利用。

Ultraviolet (UV) irradiation has emerged in the past years as one of the best water purification alternatives, with manymajor cities in Canada, USA, and Europe adopting UV as their primarydisinfection process. Ultraviolet light emitting diodes (UV-LEDs) could potentiallyrevolutionize water treatment systems by replacing UV mercurylamps, given the trend observed in LEDs recent performance enhancement and cost reduction.The proposed strategic project aims to develop the new generation of UV reactors operating with UV-LEDs. We will direct our efforts towards a comprehensive studyto investigate the fundamentals of inactivation of various pathogens byUV-LED. We will develop integrated computational models to simulate the performance and applythe model to UV-LED reactor design. Finally, we will fabricate, operate, and assess UV-LED photoreactors for water purification.Our team collectivelyhas over 25 years of experience in industryand academia on the development and application of UV reactors for water purification. We have strong support and partnership with three Canadian UV companies, contributing industrial expertise and providing a potential pathwayto commercialization of the technology.We expect this project to result in the development of the next generation of UV photoreactors, which could potentiallybe marketed within a short few years of the completion of the project. The financial benefits, potentiallyamounting to millions of dollars, will likelybe capitalized upon byCanadian manufacturers of UV reactors with worldwide sales.
