Parameters affecting the formation of perfluoroalkyl acids during wastewater treatment
82
TL;DR: PFAAs were formed during wastewater treatment and it was dependant on both process temperature and treatment type; with higher rates of formation in biological wastewater treatment plants (WWTPs) operating at longer hydraulic retention times and higher temperatures.

Per- and polyfluoroalkyl substances (PFAS) in Canadian municipal wastewater and biosolids: Recent patterns and time trends 2009 to 2021.
Sarah B. Gewurtz,Alexandra S Auyeung,Amila O. De Silva,S. Teslic,Shirley Anne Smyth +4 more
TL;DR: Canadian wastewater and biosolids contain widespread PFAS contamination, with long-chain PFAS decreasing over time due to phase-outs and regulations, while short-chain PFAS concentrations increased, indicating ongoing use as replacements.

TL;DR: An overview of PFASs detected in the environment, wildlife, and humans, and recommend clear, specific, and descriptive terminology, names, and acronyms for PFAS, can be found in this article.
The solids retention time-a suitable design parameter to evaluate the capacity of wastewater treatment plants to remove micropollutants.
TL;DR: Investigations lead to the conclusion that low effluent concentrations can be achieved in WWTPs operating SRTs higher than 10 days, which corresponds to the requirements forWWTPs situated in sensitive areas according to the urban wastewater directive of the European Community in moderate climatic zones.
