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.

水处理行业使用高达2%的发电量对活性污泥进行曝气，以优化生物活性（分解污水）。自来水公司正面临来自政府和利益相关者的巨大压力，要求其降低成本和相关的碳排放。Bactest旨在开发一种先进的在线仪器Shepherd，具有真实的时间监测和控制能力，可提高废水处理的过程效率。基于BACTEST的Cytomaia技术平台，Shepherd将展示一个技术创新的现场真实的时间监测和反馈系统，该系统测量活性污泥中的生物量，以减少曝气。Shepherd将被设计成可改造成现有的废水处理设施，除了模块化和低成本。水行业目前使用BOD（生化需氧量）作为标准测试范例。然而，由于测试需要五天，因此BOD不是用于活性污泥的真实的时间管理的合适技术。我们的项目创新是开发一个适合管理和优化工厂流程的真实的时间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，这些数据可用于真实的时间，以使工厂按照最佳设计运行，同时确保所做的工艺更改不会对工厂的强制性法规合规性产生负面影响。Shepherd的主要目标是：·使水务公司能够降低成本和碳排放·提供关于现有废水设施中生物量的真实的时间数据·确保生物工艺是最佳的·通过优化生物量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。
