This research project involving Center of Water Technology (CTE) and BioLargo Water Inc is based on a college-industry collaboration. The occurrence and persistence of pharmaceutical products (PPs) in the aquatic ecosystems lead to a negative effect on human life and cause troubles on aquatic systems. BioLargo is developing a novel electrochemical technology for water treatment termed the Electrochemical Advanced Oxidation System (EAOS). The EAOS process having "six chamber" uses flow-through electrodes, with the water flowing sequentially through an expanded graphite anode, a porous separator and an expanded graphite cathode. This R&D project aims to demonstrate the economic and environmental interest of the innovant EAOS technology in the particular case for the PPs treatment. The research project will be structure according to the following four steps. The first activity aims to evaluate and characterize the EAOS reactor having six chamber in terms of its ability to simultaneously produce ROS (H2O2, OHo, etc). The second activity will consist to develop and to optimize the EAOS efficiency to oxidize the PPs. The performance of the EAOS will evaluated under different conditions (current density, electrolysis time, pH, type of electrodes, PPs concentrations, etc). The optimization essays will conducted in batch and continuous operation mode. The third activity will consist to evaluate and to optimize the efficiency of the EAOS to treat municipal wastewater (MWW) loaded with PPs. The fourth objective was carried out to compare conventional oxidation process (O3/H2O2) and EAOS to determine the most effective process (in term of cost-effective) in treating MWW strongly loaded with PPs. A technical-economic analysis will be carried-out. This project will benefit from a unique expertise combining electrochemical oxidation techniques and analysis of emergent contaminants, and an already operational R&D infrastructures, an ingredient essential to the achievement of the objectives of the project.

这项由水技术中心(CTE)和BioLargo Water Inc.参与的研究项目是基于 产学研合作。水生生物中药物(PPS)的存在与残留 生态系统给人类生活带来负面影响，给水生系统带来麻烦。BioLargo是 开发一种新的水处理电化学技术--电化学先进技术 氧化系统(EAOS)。具有“六室”的EAOS工艺使用流过电极，具有 水依次流经膨胀石墨阳极、多孔分离器和膨胀石墨 阴极。该研发项目旨在展示创新者的经济利益和环境利益 EAOS技术在特殊情况下适用于PPS的治疗。这项研究项目将按照 分为以下四个步骤。第一项活动旨在评估和表征EAOS反应堆，该反应堆有六个 就其同时产生ROS(H_2O_2、OHO等)的能力而言。第二个活动将 包括开发和优化EAOS效率，以氧化PPS。EAOS的性能将 在不同条件下(电流密度、电解时间、pH、电极类型、PPS)进行评估 浓度等)。优化论文将以批处理和连续运行的方式进行。第三 活动将包括评估和优化EAOS处理城市污水的效率 (MWW)装载PPS。第四个目标是比较传统的氧化工艺。 (O_3/H_2O_2)和EAOS，以确定处理MWW的最有效流程(就成本效益而言) 装满了PPS。将进行技术经济分析。该项目将受益于 结合电化学氧化技术和紧急污染物分析的独特专业知识，以及 已经投入运营的研发基础设施，这是实现 项目。
