The anaerobic removal of 13 Polycyclic Aromatic Hydrocarbons (PAHs) was measured in five continuous anaerobic digestors with different feed sludge, in which abiotic losses were neglected. These feeds were chosen to generate different levels of PAH bioavailability and cometabolism within the reactors. Based on the accurate modelling of PAH sorption in sludge, the aqueous fraction (including free and sorbed-to-dissolved-and-colloidal-matter PAHs) was demonstrated to be bioavailable, which… CONTINUE READING
