To The public and the scientific community are increasingly interested in the environmental and public-health concerns associated with contaminants of emerging interest. Many wastewater treatment plants in Canada are planning to invest in upgrades to treatment infrastructure to respond to more stringent regulations aimed at improving wastewater quality and/or to protect the sources of water that are used to supply drinking water. This proposed project will ensure that investments in advanced treatment technologies have the added benefit of removing contaminants of emerging concerns (CECs); thereby, protecting the environment and providing safe and secure sources of drinking water. The objective of this collaborative R&D project is to improve the potential for using ozonation to disinfect different types of wastewater and to efficiently remove CECs from wastewater before discharge to receiving streams. Another project objective is to provide water treatment practitioners in Canadian municipalities with the information required to make scientifically sound decisions early in the process of installing additional treatment technologies in WWTPs. The collaborative project between the industry, McGill University and Trent University will build upon our collective expertise in ozonation, wastewater treatment, CECs removal and transformation and toxicity testing. This research will provide a) an improved understanding of removal and transformation of CECs in advanced treatment of WWTP effluents; b) advanced ozonation technologies for wastewater treatment; c) recommendations on ways to implement advanced oxidation technologies to mitigate the release and impacts of CECs; d) a new market for ozone gas, and e) training of HQP with a trans-disciplinary background. Our industrial partners will obtain valuable information that will allow them to further develop and test the technology in order to meet targeted disinfection and CECs removal levels. This project will allow them to take a leading position in that area of growing interest. Ensuring safe and secure water systems will benefit Canadian society by subsequent reduction of long term obvious health and environmental issues.

公众和科学界对与新出现的污染物有关的环境和公共卫生问题越来越感兴趣。加拿大的许多废水处理厂正计划投资升级处理基础设施，以应对旨在改善废水质量和/或保护用于供应饮用水的水源的更严格的法规。该拟议项目将确保对先进处理技术的投资具有去除新出现的污染物（CEC）的额外好处;从而保护环境并提供安全可靠的饮用水源。该合作研发项目的目标是提高使用臭氧消毒不同类型废水的潜力，并在排放到接收流之前有效地去除废水中的CEC。另一个项目目标是向加拿大各城市的水处理从业人员提供必要的信息，以便在污水处理厂安装额外处理技术的过程中尽早作出科学合理的决定。该行业，麦吉尔大学和特伦特大学之间的合作项目将建立在我们在臭氧化，废水处理，CEC去除和转化以及毒性测试方面的集体专业知识基础上。本研究将提供a）在污水处理厂出水的深度处理中对CEC的去除和转化的更好理解; B）用于污水处理的先进臭氧化技术; c）关于如何实施高级氧化技术以减轻CEC的释放和影响的建议; d）臭氧气体的新市场;以及e）具有跨学科背景的HQP培训。我们的工业合作伙伴将获得有价值的信息，使他们能够进一步开发和测试该技术，以满足目标消毒和CEC去除水平。该项目将使他们能够在日益感兴趣的领域占据领先地位。确保供水系统的安全和可靠将使加拿大社会受益，从而减少长期明显的健康和环境问题。
