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
Three different advanced oxidation processes (AOPs) were applied to investigate the removal of emerging contaminants (ECs) i.e. sulfamethoxazole (SMX), diclofenac (DCF) and carbamazepine (CBZ) in synthetically prepared aqueous solutions. The degradation of these substances was carried out by ozonation, sonolysis and photocatalytic oxidation, as well as by different combinations of these processes. The objectives of… Continue reading Removal of emerging contaminants in wastewater by sonolysis, photocatalysis and ozonation
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
The combination of chemical and biological treatment is a promising solution to remove emerging contaminants, e.g., pharmaceuticals, from wastewater for its future reuse. In this study, the combination of ozonation and ultrasound (O3/US) was examined as a pretreatment prior to membrane bioreactor (MBR). The effects of O3/US on the removal of selected pharmaceuticals, including diclofenac… Continue reading Removal of emerging contaminant and fouling control in membrane bioreactors by combined ozonation and sonolysis
In search of new options to achieve removal of pharmaceuticals in the environment, combined ultrasound and ozonation has become a focus of intense investigation for wastewater treatment. In this study, three pharmaceuticals were selected as model compounds for degradation experiments: diclofenac (DCF), sulfamethoxazole (SMX) and carbamazepine (CBZ). Comparison of the degradation rates for both ozonation… Continue reading Enhanced ozonation of selected pharmaceutical compounds by sonolysis
