Hydroxyl Radical Demand Monitor

点击翻译按钮获取中文摘要

This Engage project will lead to the development of the design for a prototype of a hydroxyl radical demand monitor. This instrument will benefit water treatment utilities who are using advanced oxidation processes to treat various recalcitrant chemical contaminants, in particular in the potable reuse market. The online monitor will allow the utilities to adjust the dose of their advanced oxidation system in real time to account for changes to the characteristics of the water. At present, utilities typically apply maximum doses continuously due to a lack of such a monitor, leading to unnecessarily high operating costs and energy use. The University of Toronto applicants hold a patent that has demonstrated the ability of such a monitor to work. In this Engage project, the researchers are teaming with personnel from Real Tech to conduct the necessary studies to take the conceptual design of the patent, and refine it in order to produce an optimized and practical design for a prototype.Real Tech is a leader in the design, development, and production of water quality analysers that work with disinfection and oxidation systems. They will provide a strong contribution in terms of their expertise in instrumentation and their commercial experience in the market.
