The two technologies for nutrient removal from municipal wastewater that have been gaining research and development attention over the last decade are aerobic granular sludge (AGS) and partial nitritation-anammox (PNA). The AGS process employs biomass that is much denser in structure than conventional biomass used so far in Canadian plants and allows achievement of a plant footprint that is 30% of that for conventional systems, with significantly lower aeration energy demand. The PNA process allows for removal of ammonia nitrogen (a toxic compound) without the use of expensive external carbon source and allows for 60% less aeration requirements than conventional treatment, reducing costs by30%. In order to bring these technologies to full-scale in Canada, pilot demonstrations must be performed. This project will examine the operational requirements of a continuous AGS process for total nutrient removal, as well as PNA process to address total nitrogen removal from high-strength sludge dewatering liquors (SDL), as well as from low-strength mainstream sewage. Pilot studies will be conducted at Winnipeg's North End Water Pollution Control Center (NEWPCC) to obtain parameters for full-scale design, allowing for consulting firms to become more comfortable with proposing the processes in future bids. The two processes have never been used in Canada and the research will test the development of conditions that fit Canadian climate. The NEWPCC is well suited as it has Canada's first dedicated SDL treatment facility and will immediately benefit from the results of this research. The developed knowledge base will benefit both the City of Winnipeg and University of Manitoba. Other universities will benefit from the opening of large research and development opportunities to tailor local wastewater treatment facilities to the requirements of the new process and thus develop new knowledge and provide HQP training opportunities. Municipalities across Canada will gain access to directions on how to upgrade to higher efficiency and lower costs process.

好氧颗粒污泥(AGS)和部分亚硝化-厌氧氨氧化(PNA)是近十年来研究和开发的两种去除城市污水中营养物质的技术。AGS工艺使用的生物质在结构上比加拿大工厂迄今使用的传统生物质密度高得多，并且实现了工厂占地面积是传统系统的30%，同时显著降低了曝气能量需求。PNA工艺可以在不使用昂贵的外部碳源的情况下去除氨氮(一种有毒化合物)，并允许比传统处理方法减少60%的曝气要求，降低30%的成本。为了使这些技术在加拿大全面推广，必须进行试点示范。本项目将研究用于去除总营养物质的连续AGS工艺的运行要求，以及用于解决从高浓度污泥脱水液(SDL)以及低浓度主流污水中去除总氮的PNA工艺的运行要求。将在温尼伯北端水污染控制中心(NEWPCC)进行试点研究，以获得全尺寸设计的参数，使咨询公司能够更放心地在未来的投标中提出流程。这两个过程从未在加拿大使用过，这项研究将测试适合加拿大气候的条件的发展。NEWPCC非常适合，因为它拥有加拿大第一个专门的SDL处理设施，并将立即从这项研究的结果中受益。开发的知识库将使温尼伯市和马尼托巴大学受益。其他大学将从大量研究和开发机会的开放中受益，以使当地废水处理设施适应新工艺的要求，从而发展新知识并提供HQP培训机会。加拿大各地的市政当局将获得关于如何升级到更高效率和更低成本的流程的指导。
