Cyanotoxin control strategies in drinking water

该项目得到了安大略省南部六家饮用水处理公司（多伦多、汉密尔顿、尼亚加拉、约克、达勒姆和联合供水系统）的支持，这些公司对饮用水源中蓝藻及其毒素的风险有着共同的担忧。作为他们实施风险缓解计划的更广泛努力的一部分，他们希望解决以下知识空白：(1)需要一种工具来轻松预测颗粒活性炭接触器何时达到蓝藻毒素吸附的耗尽；(2)尽管源水中蓝藻细胞浓度低至中等，但仍定量分析了蓝藻细胞在聚落和过滤器中积累的风险；(3)确定利用在线体内藻蓝蛋白探针提供蓝藻华预警的操作可行性。该研究将持续三年，包括GAC吸附模型，实验室规模的GAC“迷你柱”工具测试，以预测全面接触器的突破，中试规模的GAC吸附研究，以及全面的采样活动，以检测植物中蓝藻细胞的积累和体内藻蓝蛋白探针的响应。该项目将支持一名全日制博士生，两名本科生暑期/合作学生和一名研究化学家（兼职分配）。该项目将以学术和工业参与者的定期会议为指导，并将在研讨会上达到高潮，将专家和利益相关者聚集在一起，传播研究成果，并讨论目前关于蓝藻主题的最新技术。

This project is supported by six drinking water treatment utilities in southern Ontario (Toronto, Hamilton, Niagara, York, Durham, and the Union Water Supply System) that share a common concern about the risk of cyanobacteria and their toxins in their drinking water sources. As part of their broader efforts to implement risk mitigation programs, they wish to address the following knowledge gaps:(1) the need for a tool to easily predict when granular activated carbon contactors reach exhaustion in terms of cyanotoxin adsorption;(2) quantification of the risk of cyanobacteria cell accumulation in settlers and filters, despite low to moderate cell concentrations in source water; and (3) determining the operational feasibility of using an online in vivo phycocyanin probe to provide early warning of cyanobacteria blooms.The research will take place over three years and include modelling of GAC adsorption, lab-scale testing of GAC "minicolumn" tools to predict full-scale contactor breakthrough, pilot-scale GAC adsorption research, and full-scale sampling campaigns to detect cyanobacteria cell accumulation in plants and the response of an in vivo phycocyanin probe. The project will support one full-time Ph.D. student, two undergraduate summer/co-op students, and a research chemist (part-time allocation). The project will be guided by regular meetings with academic and industrial participants and will culminate in a workshop to bring together experts and stakeholders to disseminate the research results, and to discuss the current state-of-the-art on the topic of cyanobacteria.
