This research project involving Center of Water Technology (CTE) and BioLargo Water Inc is based on acollege-industry collaboration. The occurrence and persistence of pharmaceutical products (PPs) in the aquaticecosystems lead to a negative effect on human life and cause troubles on aquatic systems. BioLargo isdeveloping a novel electrochemical technology for water treatment termed the Electrochemical AdvancedOxidation System (EAOS). The EAOS process having "six chamber" uses flow-through electrodes, with thewater flowing sequentially through an expanded graphite anode, a porous separator and an expanded graphitecathode. This R&D project aims to demonstrate the economic and environmental interest of the innovantEAOS technology in the particular case for the PPs treatment. The research project will be structure accordingto the following four steps. The first activity aims to evaluate and characterize the EAOS reactor having sixchamber in terms of its ability to simultaneously produce ROS (H2O2, OHo, etc). The second activity willconsist to develop and to optimize the EAOS efficiency to oxidize the PPs. The performance of the EAOS willevaluated under different conditions (current density, electrolysis time, pH, type of electrodes, PPsconcentrations, etc). The optimization essays will conducted in batch and continuous operation mode. The thirdactivity 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 MWWstrongly loaded with PPs. A technical-economic analysis will be carried-out. This project will benefit from aunique expertise combining electrochemical oxidation techniques and analysis of emergent contaminants, andan already operational R&D infrastructures, an ingredient essential to the achievement of the objectives of theproject.

该研究项目涉及水技术中心（CTE）和BioLargo水公司是基于一个学院和行业的合作。医药产品在水生生态系统中的存在和持久性给人类生活带来了负面影响，并对水生生态系统造成了危害。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）。EAOS工艺具有“六室”结构，采用流通式电极，水依次流经膨胀石墨阳极、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。本研究计画将依下列四个步骤来架构。第一个活动的目的是评估和表征的EAOS反应器具有六个室的能力，同时产生活性氧（H2 O2，OHO等）。第二项活动将包括开发和优化EAOS氧化PP的效率。在不同的条件下（电流密度、电解时间、pH、电极类型、PPs浓度等）评价EAOS的性能。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的城市污水（MWW）的效率。第四个目的是进行比较传统的氧化工艺（O3/H2 O2）和EAOS，以确定最有效的工艺（在成本效益方面）在处理强负载与PP的MWW。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紧急污染物分析，以及已经运作的研发基础设施，这是实现该项目目标的重要因素。
