In situ monitoring and management of Activated Sludge for reduced energy usage and carbon emissions

为了优化生物活性（分解污水），水务行业将高达2%的发电用于给活性污泥充气。水务公司承受着来自政府和利益相关者的巨大压力，要求他们减少这一成本和相关的碳排放。Bactest旨在开发Shepherd，一种先进的在线仪器，具有实时监测和控制能力，用于提高废水处理的过程效率。基于BACTEST的CYTOMAIA技术平台，Shepherd将展示一种技术创新的现场实时监测和反馈系统，该系统可以测量活性污泥中的生物量，目标是减少曝气。水务行业以抗拒变革而闻名。除了模块化和低成本外，Shepherd还将被设计用于改造现有的废水处理设施。水工业目前使用BOD（生化需氧量）作为标准测试范例。然而，BOD并不是实时管理活性污泥的合适技术，因为该试验需要5天时间。我们的项目创新是开发一个适合管理和优化工厂流程的实时BOD代理。水务行业面临着削减运营成本和碳排放的巨大压力。Shepherd将使水务公司能够通过生成决策支持数据来减少碳排放，这些数据可以实时使用，以使工厂达到最佳设计，同时确保所做的工艺更改不会对工厂的强制性法规遵从产生负面影响。Shepherd的主要目标是：•使水务公司能够降低成本和碳排放•提供现有废水设施中生物质的实时数据•保证生物过程是最佳的•使曝气系统得到更有效的利用•通过优化生物质来减少生物对空气的需求我们估计全球市场有20,000个站点，价值7.5亿英镑。

The Water Industry uses up to 2% of all electricity generated to aerate activated sludge in order to optimise biological activity (to break down sewage). Water companies are under huge pressure from Government and stakeholders to reduce this cost and associated carbon emissions.Bactest aims to develop Shepherd, an advanced, on-line instrument with real time monitoring and control capability for improved process efficiency in wastewater treatment. Based on BACTEST’s CYTOMAIA technology platform, Shepherd will demonstrate a technologically innovative, in-situ real time monitoring and feedback system that measures biomass in activated sludge with the goal of reducing aeration.The water industry is legendary for resisting change. Shepherd will be designed to beretrofitted into existing waste water treatment facilities, in addition to being modular and low cost.The Water Industry currently uses BOD (Biochemical Oxygen Demand) as a standard testing paradigm. However BOD is not a suitable technique for real time management of activated sludge as the test takes five days. Our project innovation is to develop a real time BOD proxy suitable to manage and optimise plant processes.The Water Industry is under considerable pressure to cut both operating costs and carbon emissions. Shepherd will enable water companies to cut carbon emissions by generating decision support data that can be used in real time to operate plants to their optimal design whilst assuring that process changes made do not negatively impact the plant’s mandatory regulatory compliance.The key goals of Shepherd are to:• Enable water companies to cut cost and carbon emissions• Provide real time data on biomass in existing waste water facilities• Deliver assurance that the biological process is optimal• Enable aeration systems to be more effectively used• Reduce the biological demand for air by optimising biomassWe estimate a global market of 20,000 sites with a value of £750m.
