Appropriate Water Treatment Technology for Remote and Northern Communities

2002年12月颁布了《安大略省安全饮用水法》，以回应安大略省沃克顿市不安全饮用水导致数千人患病、导致7人死亡后提出的建议。2008年，1,700多个加拿大社区受到开水建议的影响，或由于水处理技术不足而面临水传播疾病的高风险。拟议的项目将解决包括原住民在内的加拿大小而偏远社区缺乏安全饮用水的问题。虽然有许多有效的方法来提供安全的饮用水，但许多小社区面临着空间、成本和系统复杂性等实际限制。MS Filter Systems Inc.(MSF，行业合作伙伴)拥有一套成熟的系统，适用于小型社区，包括臭氧、粗糙的生物过滤器和缓慢的砂子过滤；限制包括所需的大面积(占地面积)以及对化学品和专业知识的需求。无国界医生希望将他们的前处理工艺与超滤膜技术相结合，以减少占地面积和运营负担。这些实验将在渥太华的水处理厂进行，为期24个月。这项新技术将评估不同的臭氧水平，以及在冷水温度延长的情况下光疗的作用。将对水样进行测试，并与使用化学凝聚的现行标准进行比较。这项建议建立在目前一项研究的基础上，该研究建立了一种方法，将臭氧和膜系统的过滤结合起来，以去除溶解的有机碳、消毒副产品和微生物参数(例如：大肠杆菌)。好处：Humber和Carleton将加强他们的应用研究议程和合作伙伴关系，促进学生学习，并培养未来专业人员的技能。MS Filter Inc.将在北部小型和偏远社区扩大客户基础，并在未来10年协助在安大略省创造多达50个新工作岗位。北方小而偏远的社区将有一个更有效的选择来获得安全、清洁的饮用水。最后，水务行业通过推进处理工艺领域并在水处理领域增加高素质的人员(HQP)而受益。

The Ontario Safe Drinking Water Act was enacted in December 2002, in response to recommendations made after unsafe drinking water in Walkerton, Ontario sickened thousands of people, resulting in seven deaths. In 2008, more than 1,700 Canadian communities were affected by boil water advisories or at high risk of waterborne disease due to inadequate water treatment technologies. The proposed project will address the lack of safe drinking water in small and remote Canadian communities, including First Nations. Though there are many effective ways to provide safe drinking water, many small communities face practical restrictions such as space, costs and system complexity. MS Filter Systems Inc (MSF, the industry partner) has a proven system for small communities consisting of ozone, roughing biofilter and slow sand filtration; limitations include the large area (footprint) required and need for chemicals and expertise. MSF wants to integrate their pre-treatment process with ultrafiltration membrane technology to decrease the footprint and operational burden. The experiments will be set up at the Ottawa water treatment plant over 24 months. The new technology will evaluate different ozone levels and the role of phototherapy under prolonged cold water temperatures. Water samples will be tested and compared to the current standard, which uses chemical coagulation. This proposal builds upon a current study establishing a method to combine ozone and filtration for a membrane system to remove dissolved organic carbon, disinfection byproducts and microbial parameters (eg: E. coli). Benefits: Humber and Carleton will strengthen their applied research agendas and collaborative partnership, enhance student learning and build the skills of future professionals. MS Filter Inc will expand their client base in small and remote Northern communities and assist with the creation of up to 50 new jobs in Ontario over the next 10 years. Small and remote Northern communities will have a more efficient option to access safe, clean drinking water. Finally, the water industry benefits by advancing the field of treatment processes and adding highly qualified personnel (HQP) in the water treatment field.
