Biolargo has been developing a novel electrochemical technology for water disinfection, termed advanced**oxidation system (AOS). The packing material of the AOS is the result of continuous development of the**graphene-based electrodes over the last four years. Disinfection processes are used to effectively control**microbial pathogens (and their high health risks). However, these treatment methods carry unintentional**consequences: they react with natural and anthropogenic constituents to possibly form disinfection by-products**(DBPs) that pose a potential health problem caused by long-term exposure. Iodine-based oxidants produced by**the AOS may lead to the formation of iodinated DBPs. However, the formation or degradation of iodinated**DBPs remains largely unknown. Process optimization and improvement of equipment design and materials**require increased knowledge on the formation of iodinated DBPs. This research project will evaluate the**formation of target and untargeted DBPs produced from pure and environmentally relevant waters treated by**the AOS. The pursuit of this initiative will help a Canadian start-up company to develop critical technology for**water purification providing Biolargo a competitive edge in the market that will positively contribute to the**Canadian economy.

Biolargo一直在开发一种用于水消毒的新型电化学技术，称为高级氧化系统(AOS)。AOS的包装材料是过去四年来基于石墨烯的电极不断发展的结果。消毒过程被用来有效地控制微生物病原体(及其高健康风险)。然而，这些治疗方法会带来意想不到的后果：它们与自然和人为成分发生反应，可能形成消毒副产品**(DBPs)，长期暴露会造成潜在的健康问题。AOS产生的碘基氧化剂可能会导致碘化DBPs的形成。然而，加碘的邻苯二甲酸二苯酯的形成或降解在很大程度上仍不清楚。工艺优化和改进设备设计和材料**需要更多关于碘化二溴联苯并苯二酚形成的知识。这项研究项目将评估**AOS处理过的纯净和与环境相关的水产生的目标和非目标DBPs的形成情况。这一计划的实施将帮助一家加拿大初创公司开发**净水的关键技术，为Biolargo在市场上提供竞争优势，这将对**加拿大经济做出积极贡献。
