Biological filtration is touted as one of few methods in drinking water treatment that can reduce chemical**requirements 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 to**determine how to run a biofilter without having the tools to effectively monitor its performance. The full scale**research project will assess a suite of analytical methods to contribute to the overall knowledge base and**specifically to support the Drinking Water Services Group in the City of Ottawa, in identifying methods to**monitor and maintain their biofilters in optimum conditions. At full scale the carbon removal will be assessed**in a variety of mechanisms for a 12 month period, and will include the evaluation of monitoring tools which**could be used to help meet future needs and expectations on how to monitor biofiltration processes. Further, a**pilot scale comparison of biolfiltration and conventional filtration with different chlorine loads and backwash**wash conditions will be examined. This research will provide data on disinfection byproduct control, headloss**development, and turbidity removal under various conditions. Identification and validation will provide a**scientific 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 provide**to their customers in order to better improve and operate biofilters in their plants. From a social and**environmental perspective the outcomes are also clear - this project will facilitate drinking water treatment**plant staff will be able to better operate their facilities which can lead to a safer and more sustainable (through**reduced chemical and energy use) water production. Finally, the water industry benefits by advancing the field**of treatment processes and adding highly qualified personnel (HQP) in the water treatment field.

生物过滤被认为是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，缺乏可用且强大的工具来监测和控制 BF**（生物过滤）。监测和控制工具的识别、验证和使用对于将 BF**（生物过滤）建立为可控制且性能可预测的过程是必要的。”如果没有有效监控其性能的工具，就不可能确定如何运行生物过滤器。全面的**研究项目将评估一套分析方法，以促进整体知识库的发展，并**特别支持渥太华市的饮用水服务小组确定**监测和维持其生物过滤器处于最佳状态的方法。将在 12 个月的时间内通过各种机制全面评估碳去除量，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，还将对生物过滤和传统过滤在不同氯负荷和反洗**清洗条件下的中试规模进行比较。这项研究将提供各种条件下消毒副产物控制、水头损失**发展和浊度去除的数据。鉴定和验证将为水工业运行生物过滤器提供科学和技术进步。从商业角度来看，**这将为水处理设备供应商提供有关他们可以向客户推销和提供哪些工具**的信息，以便更好地改进和操作其工厂中的生物过滤器。从社会和**环境角度来看，结果也很明确 - 该项目将促进饮用水处理**工厂工作人员将能够更好地运营其设施，从而实现更安全、更可持续（通过**减少化学品和能源使用）的水生产。最后，水行业受益于处理工艺领域的进步和水处理领域高素质人才（HQP）的增加。
