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公司是基于一个大学-行业合作。每年从废水处理设施中产生大量的污泥。污泥中含有病原体和重金属成分，对人类健康构成威胁，因此，污泥在排入环境之前需要进行适当的处理。Kourant公司正在寻找电化学技术在污泥管理领域的应用。找到一种先进的生物电化学技术（BioElectro），可以同时实现污泥消毒和污泥细胞裂解，以增加其产生沼气的潜力，是污泥管理实践中的一个独特进步。BioElectro技术是一种处理生物固体并达到A级质量的新工艺。该反应器使用低电压梯度与增强剂，如BioxyS和铵盐，以产生放热反应，增加离子强度。该系统实现了高水平的污泥脱水和消毒。该研发项目旨在展示创新的BioElectro技术的经济和环境利益，以连续运行模式对城市污泥进行消化和处理，并在厌氧消化前的准备步骤中产生挥发性悬浮固体。本研究计画将依下列三个步骤来架构。第一项活动的目的是评估和表征生物电反应器的能力，在原位产生活性氧，以促进最大限度的消毒和细胞裂解的生物固体在放大论文。第二项活动将包括开发和优化BioElectro在批量和连续操作模式下对病原体进行灭菌和灭菌的效率。第三项活动是对现有工艺和生物电技术进行比较，以确定处理污泥的最有效工艺（就成本效益而言）。这个研究项目将受益于CTE研究人员在环境电子技术方面的专业知识和技能以及已经运作的研发基础设施;这是实现项目目标的两个基本要素
