New Publication on removal of per- and polyfluoroalkyl substances in onsite wastewater treatment

Published
By

In this study, we investigated the potential of biochar filters as a replacement or complement for sand filters for removal of per- and polyfluoroalkyl substances from wastewater in onsite sewage facilities. In a 22-weeks experiment, concentrations, removal and adsorption of nine perfluoroalkyl carboxylates (PFCAs; C3- 11) and three perfluoroalkane sulfonates (PFSAs; C4, 6, 8) and… Continue reading New Publication on removal of per- and polyfluoroalkyl substances in onsite wastewater treatment
