Adsorption was the main removal process of PFOS and PFOA in activated sludge reactors at laboratory scale. Some biodegradation of the two tested contaminants was also detected, after adsorption. Respirometric tests showed inhibition of the nitrifying bacteria up to 30% due to the presence of PFOS and PFOA. COD removal was not affected by the presence of PFOS and PFOA.
