这项研究项目涉及水技术中心(CTE)和BioLargo Water Inc.，是基于**学院和行业的合作。医药产品(PPS)在水生生态系统中的存在和存留给人类生活带来了负面影响，给水生生态系统带来了麻烦。BioLargo正在**开发一种新的水处理电化学技术，称为电化学高级氧化系统(EAOS)。具有“六室”的EAOS工艺采用流过电极，水依次流经膨胀的石墨阳极、多孔分离器和膨胀的石墨阴极。该研发项目旨在展示创新的EAOS技术在PPS处理的特殊情况下的经济和环境利益。研究项目将按照以下四个步骤**进行组织。第一项活动旨在评估和描述具有六个**室的EAOS反应器同时产生ROS(H_2O_2、OHO等)的能力。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浓度等)进行**评估。优化论文将以批处理和连续运行的方式进行。第三项**活动将包括评估和优化EAOS处理装满PPS的城市污水**的效率。第四个目标是比较传统的氧化法**(O_3/H_2O_2)和EAOS法，以确定在处理高含量聚苯硫醚的MWW**方面最有效的工艺(就成本效益而言)。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**已经运作的研发基础设施，这是实现**项目目标的关键因素。

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.
