Development and optimization of advanced Bioelectrochemical technology for sludge treatment and disinfection.

这项由水技术中心(CTE)和Kourant公司参与的研究项目是基于大学和行业的合作。废水处理设施每年会产生大量的污泥。污泥由于其病原体和重金属成分对人类健康构成威胁，因此在分散到环境中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。寻找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，以提高其沼气生产潜力，是污泥管理实践中的独特进步。生物电子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，如双氧硫和铵盐，以产生一个放热反应，离子强度增加。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技术在连续运行模式下脱水和处理城市污泥以及生产挥发性悬浮固体作为厌氧消化前的准备步骤所具有的经济和环境价值。研究项目将按照以下三个步骤进行组织。第一项活动旨在评估和表征生物电反应器在放大论文期间产生原位活性氧物种的能力，以促进生物固体的最大消毒和细胞裂解。第二项活动将包括开发和优化间歇和连续运行模式下对病原体进行脱水和灭活的生物电效率。第三项活动是比较现有工艺和生物电子技术，以确定在处理污泥方面最有效的工艺(就成本效益而言)。该研究项目将受益于CTE研究人员在环境电子技术和已经投入使用的研发基础设施方面的专业知识和技能，这是实现项目目标的两个基本要素。

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
