Antibiotics are nonbiodegradable, can survive at aquatic environments for long periods and they have a big potential bio-accumulation in the environment. They are extensively metabolized by humans, animals and plants. After metabolization, antibiotics or their metabolites are excreted into the aquatic environment. Removal of these compounds from the aquatic environment is feasible by different processes. But antibiotics are not treated in conventional wastewater treatment plants efficiently. During the last years studies with advanced oxidation processes (AOPs) for removal of these pharmaceuticals from waters has shown that they can be useful for removing them fully. Advanced oxidation processes (AOPs) can work as alternatives or complementary method in traditional wastewater treatment, and highly reactive free radicals, especially hydroxyl radicals (OH) generated via chemical (O 3 /H 2 O 2 ,O 3 /OH -), photochemical (UV/O 3 ,O 3 /H 2 O 2 ) reactions, serve as the main oxidant. This study presents an overview of the literature on antibiotics and their removal from water by advanced oxidation processes. It includes almost all types of antibiotics which are consumed by human and veterinary processes. It was found that most of the investigated advanced oxidation treatment processes for the oxidation of antibiotics in water are direct and indirect photolysis with the combinations of H 2 O 2 ,TiO 2 , ozone and Fenton's reagent.

“…Moreover, literature shows that Fenton has been utilized to treat azo dyes, phenols, nitrobenzene, COD, herbicides, and Di-(2-Ethylhexyl) phthalate (DEHP), as well as to reduce linear alkylbenzene sulfonate (LAS) in wastewater [38][39][40][41][42][43]. The photo-Fenton process also has been utilized to treat inorganic and organic components in synthetic or real aqueous solutions such as LAS, COD, Metoprolol, TOC, and pesticides [39,42,[44][45][46][47].…”

The aim of our study was to investigate the effectiveness of Fenton and photo-Fenton processes for removing anionic surfactants from aqueous solutions. The study was conducted using 200 mgL and 120 mgL -1 ferrous ion) were 69.38 and 86.66%, respectively, which is consistent with the significant increase in the rate of LAS removal efficiency with reaction time (P<0.05). In conclusion, anionic surfactants removal was significantly correlated with reaction time by both methods, but showed less dependence on H 2 O 2 and Fe 2+ concentrations.

“…Some of the advantages of UV/H 2 O 2 combination are: (a) it lacks the property of developing any chemical sludge, (b) it is effective in the removal of phenolic compounds [100], chlorinated compounds and chlorophenols [110], from effluents, (c) UV acts as a disinfectant and (d) it is effective in removal of TOC, 80-82% removal efficiency after 1-2 hours of exposure [20,105,109].…”

Textile industry is one of the major industries in the world that provide employment with no required special skills and play a major role in the economy of many countries. There are three different types of fibres used in the manufacture of various textile products: cellulose fibres, protein fibres and synthetic fibres. Each type of fibre is dyed with different types of dyes. Cellulose fibres are dyed using reactive dyes, direct dyes, napthol dyes and indigo dyes. Protein fibres are dyed using acid dyes and lanaset dyes. Synthetic fibres are dyed using disperse dyes, basic dyes and direct dyes. The textile industry utilizes various chemicals and large amount of water during the production process. About 200 L of water are used to produce 1 kg of textile. The water is mainly used for application of chemicals onto the fibres and rinsing of the final products. The waste water produced during this process contains large amount of dyes and chemicals containing trace metals such as Cr, As, Cu and Zn which are capable of harming the environment and human health. The textile waste water can cause haemorrhage, ulceration of skin, nausea, skin irritation and dermatitis. The chemicals present in the water block the sunlight and increase the biological oxygen demand thereby inhibiting photosynthesis and reoxygenation process. The effluent water discharged from the textile industries undergoes various physio-chemical processes such as flocculation, coagulation and ozonation followed by biological treatments for the removal of nitrogen, organics, phosphorous and metal. The whole treatment process involves three steps: primary treatment, secondary treatment and tertiary treatment. The primary treatment involves removal of suspended solids, most of the oil and grease and gritty materials. The secondary treatment is carried out using microorganisms under aerobic or anaerobic conditions and involves the reduction of BOD, phenol and remaining oil in the water and control of color. The tertiary treatment involves the use of electrodialysis, reverse osmosis and ion exchange to remove the final contaminants in the wastewater. The major disadvantages of using the biological process are that the presence of toxic metals in the effluent prevents efficient growth of microorganisms and the process requires a long retention time. The advanced oxidation processes is gaining attention in the recent days due to the ability to treat almost all the solid components in the textile effluents. The photo oxidation of the effluents is carried out using H 2 O 2 , combination of H 2 O 2 and UV and Combination of TiO 2 and UV. Advanced oxidation process generates low waste and uses hydroxyl radicals (OH • ) as their main oxidative power. The hydroxyl radicals (OH • ) are produced by chemical, electrical, mechanical or radiation energy and therefore advanced oxidation processes are classified under chemical, photochemical, catalytic, photocatalytic, mechanical and electrical processes. The effluents treated with advanced oxidation process were ...
