项目摘要
Driven by forthcoming regulations on perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid
(PFOA) and their related fluorinated surfactants, there is a great need to develop cost-effective and efficient
treatment technologies for removing these persistent and toxic chemicals from impacted waters, especially the
waters contaminated by aqueous film-forming foams (AFFF). Because these surfactants are highly stable and
resistant to microbial or chemical attacks, conventional biological or chemical treatments are either not
effective or are very cost prohibitive. A clear effective and economical alternative is to use appropriate sorbent
materials to capture these contaminants. Supported by an Engage Grant, a new collaborative partnership was
established between Sanexen and the applicant at McGill University to evaluate the company's trademark
multi-step filtration process with respect to the efficacy and efficiency of the AFFF treatment. Total removal
efficiencies of 90-99% have been achieved in lab-scale and field-scale treatment systems. The results obtained
in the previous work warrant going forward to further optimizing the trademark process. Specifically, the
project will examine the impact of hydraulic retention time, concentration of colloidal materials, and chemical
compositions of AFFFs. The continuous collaboration will benefit the industrial partner in improving its
trademark treatment process for AFFF removal and expanding its client base. The project will benefit Canada's
economy and environment by reducing the cost of dealing with PFOS and PFOA and their related persistent
organic contaminants in many federal contaminated sites.

因此,非常需要开发具有成本效益和高效的全氟辛酸(PFOA)及其相关的含氟表面活性剂,
处理技术,用于从受影响的沃茨水域中去除这些持久性和有毒化学物质,特别是
被水成膜泡沫(AFFF)污染的沃茨。因为这些表面活性剂是高度稳定的,
