| VOLATILIZATION AND FATE OF POLYCYCLIC AROMATIC HYDROCARBONS DURING WASTEWATER TREATMENT | |
Abstract/OtherAbstract

Polycyclic aromatic hydrocarbons (PAHs) are common environmental contaminants, some of which are hazardous to human health. In an effort to better understand the fate of these contaminants during wastewater treatment, samples were taken from multiple locations in a mid-sized treatment plant in Carmel, Indiana and analyzed for naphthalene and phenanthrene. Of particular interest was the volatilization of these semi-volatile PAHs, and so air samples of the off-gas from the aeration tank were collected with a combination of polyurethane foam and XAD-2 resin adsorbent. Tests showed that volatilization was minimal and should not be a concern unless there are unusually high concentrations of PAHs in the influent. Analysis also indicated that the amount of adsorption to the solids in the treatment system affected how well the PAHs were bio-degraded and removed with the solids, and hence, the overall removal efficiency. |
