Biological filtration is touted as one of few methods in drinking water treatment that can reduce chemicalrequirements and energy needs in drinking water facilities. In fact, the Water Environment Foundation (2013)further states "In North America, there is a lack of available and robust tools for monitoring and control of BF(biofiltration). Identification, validation, and use of monitoring and control tools are necessary to establish BF(biofiltration) as a process that can be controlled and whose performance can be predicted." It is impossible todetermine how to run a biofilter without having the tools to effectively monitor its performance. The full scaleresearch project will assess a suite of analytical methods to contribute to the overall knowledge base andspecifically to support the Drinking Water Services Group in the City of Ottawa, in identifying methods tomonitor and maintain their biofilters in optimum conditions. At full scale the carbon removal will be assessedin a variety of mechanisms for a 12 month period, and will include the evaluation of monitoring tools whichcould be used to help meet future needs and expectations on how to monitor biofiltration processes. Further, apilot scale comparison of biolfiltration and conventional filtration with different chlorine loads and backwashwash conditions will be examined. This research will provide data on disinfection byproduct control, headlossdevelopment, and turbidity removal under various conditions. Identification and validation will provide ascientific and technical advance for the water industry in operating biofilters. From a commercial perspective,this would provide water treatment equipment suppliers information on what tools they can market and provideto their customers in order to better improve and operate biofilters in their plants. From a social andenvironmental perspective the outcomes are also clear - this project will facilitate drinking water treatmentplant staff will be able to better operate their facilities which can lead to a safer and more sustainable (throughreduced chemical and energy use) water production. Finally, the water industry benefits by advancing the fieldof treatment processes and adding highly qualified personnel (HQP) in the water treatment field.

生物过滤被吹捧为饮用水处理中为数不多的可以减少饮用水设施的化学要求和能源需求的方法之一。事实上，水环境基金会(2013)进一步指出：“在北美，缺乏监测和控制生物过滤(BF)的可用和强大的工具。识别、验证和使用监测和控制工具对于将BF(生物过滤)确立为一个可控制和其性能可预测的过程是必要的。”如果没有有效监控生物滤池性能的工具，就不可能确定如何运行生物滤池。整个规模的研究项目将评估一套分析方法，以促进整个知识库，特别是支持渥太华市饮用水服务小组确定监督和维护其生物滤池处于最佳状态的方法。在12个月的时间里，将在各种机制中对碳去除进行全面评估，并将包括对监测工具的评估，这些工具可用于帮助满足未来对如何监测生物过滤过程的需求和期望。此外，还将考察生物过滤和常规过滤在不同氯负荷和反冲洗条件下的中试规模比较。本研究将为不同条件下的消毒副产物控制、水头损失发展和浊度去除提供数据。鉴定和验证将为水务行业运行生物滤池提供科学和技术上的进步。从商业角度来看，这将为水处理设备供应商提供信息，说明他们可以销售和向客户提供哪些工具，以便更好地改进和运行其工厂中的生物滤池。从社会和环境的角度来看，结果也是明确的--该项目将促进饮用水处理厂的工作人员更好地操作他们的设施，从而(通过减少化学和能源消耗)实现更安全和更可持续的水生产。最后，水务行业受益于推进处理工艺领域，并在水处理领域增加高素质人员(HQP)。
