Investigation and analysis at full and pilot scale on operational procedures of biofiltration unit**processes in drinking water treatment

生物过滤被吹捧为饮用水处理中为数不多的方法之一，可以减少饮用水设施中的化学物质需求和能源需求。事实上，水环境基金会（2013年）** 进一步指出，“在北美，缺乏监测和控制BF**（生物过滤）的可用和可靠的工具。识别，验证和使用监测和控制工具是必要的，以建立BF**（生物过滤）作为一个过程，可以控制，其性能可以预测。“如果没有有效监测其性能的工具，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，以促进整体知识基础，** 特别是支持渥太华市的饮用水服务集团，确定方法，以 ** 监测和保持其生物过滤器在最佳条件下。将在12个月的时间内通过各种机制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，还将对生物过滤和传统过滤在不同氯负荷和反冲洗条件下的中试规模比较进行检查。这项研究将提供数据的消毒副产物控制，水头损失 ** 的发展，和浊度去除在各种条件下。鉴定和验证将为水处理行业运行生物过滤器提供一个科学和技术的进步。从商业角度来看，** 这将为水处理设备供应商提供信息，说明他们可以向客户销售和提供什么工具，以便更好地改进和操作其工厂中的生物过滤器。从社会和 ** 环境的角度来看，结果也是明确的-该项目将促进饮用水处理 ** 工厂工作人员将能够更好地操作他们的设施，从而导致更安全和更可持续的（通过 ** 减少化学品和能源的使用）水生产。最后，水处理行业通过推进处理工艺领域和在水处理领域增加高素质人员（HQP）而受益。

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.
