“…In addition, ozone treatment is often employed for pathogenic microorganism reduction (i.e., disinfection) (Loeb, 2002;Paraskeva and Graham, 2002). Some of the advantages of these processes include complete mineralization of organic contaminants, production of less harmful and more biodegradable by-products, and ability to handle fluctuating flow rates and compositions (Zhou and Smith, 2001).…”

A vast number of pharmaceuticals have been detected in surface water and drinking water around the world, which indicates their ineffective removal from water and wastewater using conventional treatment technologies. Concerns have been raised over the potential adverse effects of pharmaceuticals on public health and aquatic environment. Among the different treatment options, ozonation and advanced oxidation processes are likely promising for efficient degradation of pharmaceuticals in water and wastewater. Recent progress of advanced oxidation of aqueous pharmaceuticals is reviewed in this paper. The pharmaceuticals and non-therapeutic medical agent of interest include antibiotics, anticonvulsants, antipyretics, beta-blockers, cytostatic drugs, H 2 antagonists, estrogenic hormone and contraceptives, blood lipid regulators, and X-ray contrast media.Keywords Ozone, Advanced Oxidation Processes, Antibiotic, Antipyretic, Anticonvulsants, Blood Lipid Regulator, Beta-blocker, Cytostatic Drug, X-Ray Contrast Media, Estrogens INTRODUCTIONA large amount of numerous prescription and nonprescription drugs of different classes are consumed annually throughout the world. These pharmaceutical compounds include antipyretics, analgesics, blood lipid regulators, antibiotics, antidepressants, chemotherapy agents, and contraceptive drugs. After the administration, these compounds are partially metabolized and excreted in the urine and feces, and subsequently enter into sewage treatment plants where these compounds are treated, along with other organic and inorganic constituents in wastewater. However, it has been shown that some of these pharmaceutical compounds are not completely removed in sewage treatment plants (Halling-Sørensen et al., 1998;Ternes, 1998;Ternes et al., 1999;Heberer, 2002;Boyd et al., 2003). As a result, they have been found in some sewage treatment plant effluents as well as in surface water and groundwater in many countries (Ternes, 1998;Sacher et al., 2001;Soulet et al., 2002;Miao et al., 2004). In addition, non-therapeutic medical agents such as X-ray contrast agents (also known as radiocontrasts) and some veterinary drugs have been also found in the aquatic environment (Ternes and Hirsch, 2000;Drewes et al., 2001;Ku¨mmerer, 2001). Although some of these pharmaceuticals and their metabolites can be partially removed through sorption and biotic or abiotic degradation in the environment, they can eventually reach drinking water sources. Several recent studies have revealed that conventional water treatment processes cannot remove some prescription and non-prescription drugs completely from source waters (Ternes et al., 2002;Stackelberg et al., 2004;Jones et al., 2005a).The frequent occurrence of pharmaceuticals in the aquatic environment as well as in finished drinking water has raised a concern about their potential impact on environmental and public health. Some of the adverse effects caused by pharmaceutical pollution include aquatic toxicity, resistant development in pathogenic bacteria, genotoxicity, and...

“…By adding hydrogen peroxide to the water, the ozone transfer from gas phase to liquid phase can be improved due to an increase in ozone reaction rates. The AOP (Advanced Oxidation Process) ozone-hydrogen peroxide is a common used purification treatment (Perkowski et al, 2000;Loeb, 2002) for ground water and surface water contaminated with refractory compounds. When ozone and peroxone processes are compared one sees an advantage for ozone, due to its electrophylic character, regarding oxidizing compounds with double bounds, iron and manganese and for its disinfection ability.…”
