The objective of the project is to demonstrate that Biological Aerated Filtration (BAF) treatment systems that operate as immersed biofilters are capable of significant nitrification at cold temperatures representative of Canadian climates. The research addresses a critical need to improve our ability to treat wastewaters that contain the toxic contaminant ammonia under extreme environmental conditions such as those experienced in Canada. We propose to conduct a series of carefully planned and executed laboratory experiments using bench-top BAF systems followed by a set of pilot-scale experiments conducted at a Quebec treatment facility. The proposed research involves the use of several state-of-the-art techniques for the characterization of biofilm in the reactor systems (e.g., confocal laser scanning microscopy, fluorescence in-situ hybridization, scanning electron microscopy). Determining the potential of the BAF system for nitrification of contaminated wastewaters at low temperatures will be of significant value to the partner organization, John Meunier Inc. The technical information obtained as a result of this research will provide JMI with the means to evaluate the potential to increase their target market for their technology. Our results will also contribute to the general body of knowledge in the areas of (i) nitrifying biofilms, (ii) wastewater treatment and (iii) nitrification at cold temperatures.

该项目的目的是证明生物曝气过滤（BAF）处理系统作为浸入式生物过滤器，能够在代表加拿大气候的寒冷温度下进行显著的硝化作用。这项研究解决了一个迫切需要，即提高我们在极端环境条件下处理含有有毒污染物氨的废水的能力，比如在加拿大经历的那些环境条件。我们建议使用台式BAF系统进行一系列精心规划和执行的实验室实验，然后在魁北克处理设施进行一系列中试规模的实验。拟议的研究涉及使用几种最先进的技术来表征反应器系统中的生物膜（例如，共聚焦激光扫描显微镜，荧光原位杂交，扫描电子显微镜）。确定BAF系统在低温下硝化污染废水的潜力对合作组织John Meunier Inc.具有重要价值。这项研究所获得的技术资料将为JMI提供手段，以评估增加其技术目标市场的潜力。我们的研究结果也将有助于(i)硝化生物膜，（ii）废水处理和（iii）低温硝化领域的一般知识体系。
