Research equipment requested is going to be used in analysis of nutrients - nitrogen and phosphorus in water and wastewater.  Currently nutrient removal is the biggest issue on the environmental agenda in Manitoba.  The Applicant chairs the International Water Association's specialist group on Nutrient Removal and Recovery and has seen the nutrient problem (over-fertilization of lakes and streams also called eutrophication) becoming number one priority around the world.  The Applicants have been engaged in biological nutrient removal for the last two decades using a 30 years old colorimetric auto-analyzer, which although continuously refurbished and upgraded, has reached the limit of its functional life and cannot provide quality required nor process the numbers of samples that are analyzed in the environmental engineering laboratories.   The Civil Engineering and Biosystems Engineering students share the laboratories (the environmental laboratories are contiguous) and all need the new equipment to conduct research for example on: nitrification (ammonia oxidation) in cold temperatures (Mr Hwang) and after anoxic stress (Ms Wong); total nitrogen removal after ozone treatment of the biomass (Ms Dytczak); nitrogen removal in biofilm reactors (Ms Celmer); autotrophic denitrification (Ms Celmer, Mr Hwang, Dr Rezania); use of industrial waste or generation of carbon for denitrification (Mr Chen); macrophyte harvesting to prevent nutrient recycle in the Red River delta (Mr Grosshank); nutrient removal in granular activated sludge reactors (Ms Zhou); anaerobic ammonia removal (Mr Jaroszynski); manure treatment in membrane bioreactors (Mr Yang).   Our work has economic benefits.  Winnipeg alone is facing over $1 B potential expenditures on wastewater infrastructure and upgrades to its three plants.  Any improvements in the nutrient removal process and associated solids management will be translated to lower burden to the Canadian taxpayer.

所要求的研究设备将用于分析水和废水中的营养物质-氮和磷。目前，营养物质去除是马尼托巴省环境议程上最大的问题。申请者是国际水协会营养物质去除和恢复专家小组的主席，并已看到营养问题(湖泊和溪流的过度施肥也称为富营养化)成为世界上的头等大事。在过去的20年里，申请者一直在使用已有30年历史的比色自动分析仪进行生物营养去除，尽管不断翻新和升级，已经达到其使用寿命的极限，无法提供所需的质量，也无法处理在环境工程实验室分析的样本数量。土木工程和生物系统工程专业的学生共享实验室(环境实验室是相连的)，都需要新设备进行研究，例如：低温下的硝化(氨氧化)(黄先生)和缺氧应激后的硝化(黄女士)；生物质臭氧处理后的总氮去除(Dytczak女士)；生物膜反应器中的氮去除(Ms Celmer)；自养反硝化(Celmer女士、Hwang先生、Rezania博士)；使用工业废物或产生碳进行反硝化(Chen先生)；在红河三角洲收获大型植物以防止营养循环(Grosshank先生)；颗粒活性污泥反应器中的养分去除(周女士)；厌氧氨的去除(Jaroszynski先生)；膜生物反应器中的粪便处理(杨先生)。他说，我们的工作具有经济效益。仅温尼伯一家就面临着超过10亿美元的潜在支出，用于废水基础设施和三个工厂的升级。此外，养分去除过程和相关固体管理方面的任何改进都将转化为减轻加拿大纳税人的负担。
