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 Water Inc，基于Acollege-Induspry合作。水生生系统中药品（PPS）的发生和持久性导致对人类生活产生负面影响，并对水生系统造成麻烦。 Biolargo ISDEVENGET一种新型的电化学技术称为电化学晚期氧化系统（EAOS）。具有“六个腔室”的EAOS工艺使用流动电极，依次通过扩展的石墨阳极，多孔分离器和扩展的石墨座状态流动。该研发项目旨在证明在PPS治疗的特定情况下，Innovanteaos技术的经济和环境利益。研究项目将根据以下四个步骤是结构。第一个活动旨在评估和表征具有六杆的EAO反应器，以同时产生ROS（H2O2，OHO等）。第二个活动将要开发和优化EAOS效率以氧化PPS。在不同条件下（电流密度，电解时间，pH，电极类型，ppsConconcontrations等）将进行EAOS的性能。优化论文将以批处理和连续操作模式进行。第三次将评估和优化EAO的效率，以处理装有PPS的市政废水（MWW）。进行第四个目标以比较常规氧化过程（O3/H2O2）和EAOS，以确定在处理MWWSTRONG LODALY PPS时最有效的过程（成本效益）。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新兴污染物的分析，Andan已经运营的研发基础设施，这是实现Promoject目标至关重要的成分。
