Abstract
This study was carried out to investigate the removability of polycyclic aromatic hydrocarbon (PAH) compounds existed in automotive industry treatment sludge. The impacts of temperature, UV, titanium dioxide (TiO2), and diethyl amine (DEA) were studied in a controlled device which was specifically designed for this study. Sludge samples were collected from the treatment plant of an automotive manufacturing facility in Bursa, Turkey. The Sigma(10) PAH concentration value in the sludge was 4480 +/- 1450ng/g dry matter (DM). Sigma(10) PAH removal ratio was 30% at 37 degrees C without UV irradiation. Moreover, the PAH content in the sludge was reduced up to 65% through applying UV irradiation. This figure reached 100% by using photo-catalysts (TiO2 or DEA) at the rate of 20% of the DM of the sludge.
