Wastewater Treatment
Occurrence and Fate of Polycyclic Aromatic Hydrocarbons (PAHs)
Advances in Water and Wastewater Transport and Treatment Series

Polycyclic Aromatic Hydrocarbons (PAHs) are a group of semi-volatile organic compounds that are formed during the incomplete burning of gas, coal, oil, wood, garbage, or other organic substances. PAHs are a concern because a number of them have been identified as genotoxic and/or carcinogenic. They pose a threat to ecological systems and can cause health problems. A significant source of PAHs is the effluent of wastewater treatment plants. This book explores the occurrence and the treatability of PAHs in wastewater treatment.

Introduction. PAHs in natural waters: natural and anthropogenic sources, and environmental behavior. Quantitative changes of PAHs in water and in wastewater during treatment processes. Occurrence of PAHs in water resources in Tunisia. Occurrence, removal and fate of polycyclic aromatic hydrocarbons and volatile organic compounds in municipal conventional activated sludge processes and membrane bioreactors. PAHs in wastewater and removal efficiency in conventional wastewater treatment plants. Advanced oxidation potential of PAHs in the environment and engineered systems. PAH treatment in wastewater treatment facilities during wet and dry weather.
