项目摘要

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中**石墨烯基电极连续发展的结果。消毒过程用于有效控制**微生物病原体（及其高健康风险）。但是，这些治疗方法具有无意的后果：它们与自然和人为成分的反应可能形成消毒副产品**（DBPS），从而构成了由长期暴露引起的潜在健康问题。 **产生的基于碘的氧化剂可能导致形成碘的DBP。但是，碘化** dbps的形成或降解在很大程度上是未知的。设备设计和材料的过程优化和改进需要增加有关碘化型DBP形成的知识。该研究项目将评估由AOS处理的纯和环境相关的水域产生的目标和非目标DBP的**形成。对这项计划的追求将有助于加拿大初创公司开发重要的技术，以**水净化为Biolargo提供市场上的竞争优势，这将为**加拿大的经济做出积极贡献。
