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.

这个研究项目涉及水技术中心（CTE）和BioLargo水公司是基于一个 ** 大学产业合作。医药产品在水生态系统中的存在和持久性对人类生活造成负面影响，并对水生态系统造成危害。BioLargo正在开发一种新的电化学水处理技术，称为电化学高级氧化系统（EAOS）。具有“六室”的EAOS工艺使用流通电极，其中水依次流过膨胀石墨阳极、多孔隔膜和膨胀石墨阴极。该研发项目旨在展示创新 **EAOS技术在PP处理特定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表征具有六个 ** 室的EAOS反应器同时产生ROS（H2 O2，OHO等）的能力。第二项活动将包括开发和优化EAOS氧化PP的效率。EAOS的性能将在不同条件下（电流密度、电解时间、pH、电极类型、PP ** 浓度等）进行 ** 评估。优化试验将以分批和连续操作模式进行。第三项 ** 活动将包括评估和优化EAOS处理含有PP的城市废水 **（MWW）的效率。第四个目的是比较传统的氧化工艺 **（O3/H2 O2）和EAOS，以确定处理强负载PP的MWW** 的最有效的工艺（从成本效益的角度来看）。将进行技术经济分析。该项目将受益于独特的专业知识，结合电化学氧化技术和新兴污染物的分析，以及已经运作的研发基础设施，这是实现项目目标的重要因素。
