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

紫外线（UV）照射在过去几年已经成为最好的水净化替代方法之一，加拿大、美国和欧洲的许多主要城市都采用紫外线作为主要的消毒过程。紫外发光二极管（UV- led）可能会通过取代紫外汞灯来彻底改变水处理系统，鉴于led最近的性能增强和成本降低的趋势。拟议的战略项目旨在开发使用UV- led的新一代UV反应器。我们将致力于一项全面的研究，以调查yuv - led灭活各种病原体的基本原理。我们将开发集成计算模型来模拟性能，并将该模型应用于UV-LED反应器设计。最后，我们将制造、操作和评估用于水净化的UV-LED光反应器。我们的团队在水净化UV反应器的开发和应用方面拥有超过25年的工业和学术界经验。我们与三家加拿大UV公司有强有力的支持和合作伙伴关系，提供工业专业知识，并为该技术的商业化提供潜在途径。我们期望这个项目能促进下一代紫外光反应器的发展，在项目完成后的短短几年内就有可能推向市场。经济效益，潜在达数百万美元，可能会被加拿大紫外线反应器制造商在全球销售资本化。

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.
