1. 1. Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Anna Östlund; [2015]
   Keywords : PFASs; perfluoroalkyl substances; removal efficiency; granular activated carbon; GAC; anion exchange; AE; dissolved organic carbon; DOC;

   Abstract : Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. READ MORE

   Abstract : Denitrification is a microbially-catalyzed reaction which reduces nitrate to N2 through a series of intermediate nitrogen compounds. Nitrate is a nutrient and its release into the environment may lead to eutrophication, depending on the amount that is released and the state of the recipient. READ MORE
