Volatile organic compounds (VOCs) laden emissions are becoming of great concern in the context of atmospheric pollution, due to their adverse effects on both the environment and human health. Physical–chemical processes (PCPs) and biological processes (BPs) represent widely used solutions for the VOCs degradation. The process limitation by recalcitrant nature and toxicity of the secondary… Continue reading Abatement of Atmospheric Pollutants: UV–Ozone Oxidation for the Degradation of Gaseous Toluene
The release of air pollutants from the operation of wastewater treatment plants (WWTPs) is often a cause of odor annoyance for the people living in the surrounding area. Odors have been indeed recently classified as atmospheric pollutants and are the main cause of complaints to local authorities. In this context, the implementation of effective treatment… Continue reading Full-scale odor abatement technologies in wastewater treatment plants (WWTPs): A review
Ultrasonication with water recirculation slightly enhanced the removal of toluene compared to water recirculation alone due to conjunction of pyrolysis and hydroxyl radical oxidation with absorption. On the other hand, the addition of ozone with ultrasonication decreased the removal efficiency due to scavenging of hydroxyl radicals. The reaction rate for ozone and OH radicals produced… Continue reading Degradation of gaseous vocs by ultrasonication: Effect of water recirculation and ozone addition
The growing expectations of the population and the increasingly stringent regulations about air pollution have resulted in the need to minimize and conveniently treat the waste gas from different emission sources. The emissions from a large variety of plants, including waste and wastewater treatment plants, result mainly from the degradation of organic matter. These emissions… Continue reading Abatement of odour emissions by UV/ozone oxidation process
