Ensuring access to clean water for everyone is one of United Nations' Sustainable Development Goals. Despite progress, billions of people around the world do not have secure access to this resource. It is predicted that half of the world population will be living in water-stressed conditions by 2050. While Canada has abundant freshwater, our water resources are facing increasing pressures due to climate change and pollution.Recycling wastewater, such as greywater- wastewater without any contributions from toilet water- could provide a path to reduce our reliance on fresh water. Greywater represents a significant portion of household wastewater with daily production of up to several hundred liters per person. Recycling greywater not only reduces the amount of freshwater needed but also significantly lowers the burden on municipal water treatment infrastructure.In this project, we propose to develop greywater recycling systems for individual residence application. We will develop greywater recycling systems in which pollutants are removed through an advanced electrochemical oxidation process. Our approach involves an in-situ formation of strong oxidant, hydroxyl radical, that is capable of decomposing organic pollutants in greywater. We believe that this approach could be applied for the treatment of other wastewater sources. The commercialization of the greywater treatment system developed in this project is expected to create new job opportunities, including manufacturing specialists and installation/service technicians in Ontario and Canada.

确保每个人都能获得清洁水是联合国的可持续发展目标之一。尽管取得了进展，世界各地仍有数十亿人无法安全地使用这一资源。据预测，到2050年，世界人口的一半将生活在缺水条件下。虽然加拿大拥有丰富的淡水资源，但由于气候变化和污染，我们的水资源正面临越来越大的压力。回收废水，如灰水--没有任何厕所水的废水--可以提供一条途径，减少我们对淡水的依赖。灰水占家庭废水的很大一部分，每人每天产生高达数百升的废水。回收灰水不仅减少了所需的淡水量，而且显著减轻了市政水处理基础设施的负担。在这个项目中，我们建议开发适用于个人住宅的灰水回收系统。我们将开发废水回收系统，通过先进的电化学氧化工艺去除污染物。我们的方法包括原位形成能够分解灰水中有机污染物的强氧化剂--羟基自由基。我们相信，这种方法也可以应用于其他污染源的处理。该项目开发的灰水处理系统的商业化预计将创造新的就业机会，包括安大略省和加拿大的制造专家和安装/服务技术人员。
