Reference number : GC-2017-Q3-00628, amendment number : , agreement type : G, recipient legal name : de Lannoy, Charles-François (McMaster University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Water is the most important resource for humanity. Yet, abundant and safe drinking water is not available to_x000D_
over 60% of the world's population. The availability of potable water is under threat with growing global_x000D_
populations, over-tapped ground water supplies, the continued contamination of fresh water sources, and the_x000D_
drought-inducing impacts of climate change. Potable reuse is the process of treating wastewater to the level at_x000D_
which it can be safely consumed as drinking water. This process is critical to address global drinking water_x000D_
shortages, specifically in large municipal centers and/or drought-prone regions of the world. Treatment of_x000D_
wastewater to produce drinking water must be done safely. In order to do this a combination of membrane_x000D_
treatment and UV disinfection has been proposed. Membrane treatment using a process train of microfiltration_x000D_
(MF) and reverse osmosis (RO) membranes removes all the contaminants in wastewater. UV disinfection is the_x000D_
final process and it inactivates all bacteria and viruses that may remain in the post-membrane treated water._x000D_
During the membrane filtration steps the membranes can become fouled by the constituents of wastewater. To_x000D_
prevent RO membrane fouling during operation anti-scalants and anti-foulants, such as chloramine, are_x000D_
periodically added to the feed water. These anti-scalants and anti-foulants, however, pass through the_x000D_
membrane and enter the final UV disinfection step. These anti-scalants and anti-foulants scavenge UV light_x000D_
reducing UV transmittance. The UV disinfection has a decreased effectiveness when the UV transmittance is_x000D_
reduced, thereby necessitating a larger UV AOP system size to account for the potential UV scavenging. The_x000D_
proposed project investigates new membranes that can reduce the amount of anti-foulants and anti-scalants_x000D_
required, which will maximize the effectiveness of the UV disinfection process. Reducing anti-foulant and_x000D_
anti-scalant use will reduce the overall cost of treating wastewater for potable reuse., program purpose french : Water is the most important resource for humanity. Yet, abundant and safe drinking water is not available to_x000D_
