This research project involving Center of Water Technology (CTE) and Kourant Inc is based on acollege-industry collaboration. Large amounts of sludge are produced annually from wastewater treatmentfacilities. Sludge poses a threat on human health due to its pathogen and heavy metal constituents andtherefore, requires appropriate treatment before dispersion into the environment. Kourant Company is looking for applications of electrochemical technology in the domain of sludge management. Finding out an advanced Bioelectrochemical technology (BioElectro) that can achieve simultaneously sludge disinfection and sludge cell lysis to increase its potential for biogas production is a unique advancement in sludge managementpractices. The BioElectro technology is a new process to treat biosolids and achieve Class A quality. Thereactor uses a low voltage gradient in conjunction with enhancers such as BioxyS and ammonium salts in orderto produce an exothermic reaction with increased ionic strength. The system achieves a high level of sludge dewatering and disinfection. This R&D project aims to demonstrate the economic and environmental interest of the innovant BioElectro technology to dewater and treat municipal sludge in continuous operation mode as well as to produce volatile suspended solids as a preparation step before anaerobic digestion. The researchproject will be structure according to the following three steps. The first activity aims to evaluate andcharacterize the Bioelectro reactor in terms of its ability to produce in situ reactive oxygen species to promote maximum disinfection and cell lysis of biosolids during scale-up essays. The second activity will consist todevelop and to optimize the BioElectro efficiency to dewater and inactivate pathogens under batch andcontinuous operation mode. The third activity was carried out to compare existing process and BioElectrotechnology to determine the most effective process (in term of cost-effective) in treating sludge. This research project will benefit from the expertise and skills of CTE researchers in environmental electro-technology and an already operational R&D infrastructure; two essential ingredients for achieving the project objectives

该研究项目涉及水技术中心（CTE）和Kourant Inc，基于Acollege-Industry合作。每年通过废水处理能力生产大量污泥。由于其病原体和重金属成分，污泥对人类健康构成威胁，因此需要在分散到环境之前进行适当的治疗。库兰特公司（Kourant Company）正在寻找电化学技术在污泥管理领域的应用。找出可以同时实现污泥消毒和污泥细胞裂解以提高其生产沼气生产的潜力的先进生物电化学技术（生物电解），这是污泥管理式实践的独特进步。生物电力技术是治疗生物固体并达到A类质量的新过程。 ThereActor与诸如生物氧和铵盐等增强剂结合使用低电压梯度，以产生离子强度增加的放热反应。该系统可实现高水平的污泥脱水和消毒。该研发项目旨在证明创新的生物电子技术的经济和环境利益，以脱水和处理连续操作模式下的市政污泥，并在厌氧消化之前产生挥发性悬浮的固体作为准备步骤。研究项目将根据以下三个步骤进行结构。第一种活性旨在根据其产生原位活性氧物质的能力来评估并表达生物电反应器，以促进缩放论文期间生物固体的最大消毒和细胞裂解。第二个活动将构成大型开发，并在批处理和连续操作模式下优化对脱水和灭活病原体的生物效率。进行了第三项活动以比较现有过程和生物电子技术，以确定治疗污泥中最有效的过程（具有成本效益）。该研究项目将受益于CTE研究人员在环境电学技术和已经运营的研发基础设施方面的专业知识和技能；实现项目目标的两种基本要素
