“…Various studies have published the effective AOPs treatment for the removal of antibiotics from wastewater [63][64][65][66][67]. High-quality and effective publications relevant with the AOP studies on the mechanisms and applications of water and wastewater treatments have been pronounced for last two decades.…”

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.

“…Specific surface area and pore structure of LWAC Identifying the pore structure of adsorbent, which is commonly determined by the adsorption of inert gases, is an essential procedure before designing the adsorption process (Saritha et al, 2007). Figure 1 shows the adsorption-desorption isotherm of N 2 at 77 K. Adsorption data were obtained over the relative pressure, P/P 0 , range from 10 −7 to 1.…”

In this study, the efficiency of activated carbon produced from Henna wood was studied to remove herbicide from aqueous solutions by adsorption. The parameters that affect the adsorption such as contact time, activated carbon dosage, initial concentration of adsorbate, stirring rate, temperature, and pH on bentazon adsorption were studied. The use of Henna wood as a raw material to produce activated carbon by physical activation was investigated. The activated carbons produced were characterized by nitrogen adsorption isotherms and point of zero charge properties. Brunauer, Emmett and Teller (BET) surface area of the activated carbon was determined. The removal of herbicide from aqueous solutions by adsorption on activated carbon produced was studied. The results of the present investigation showed that activated carbons prepared from Henna wood have good adsorption capacity for the removal of bentazon from aqueous solution. The Langmuir model provides the best correlation of the experimental equilibrium data. Adsorption isotherm according to BET classification was of Type I. The adsorption isotherms of bentazon revealed that adsorption increased as the concentration increases up to a saturation point. Enthalpy, entropy and free enthalpy adsorption have a negative value indicating that the adsorption of bentazon on the Henna wood activated was feasible, spontaneous and exothermic at 20 to 40°C.

“…Modirshahla and Behnajady studied the degradation of Malachite green using UV/H 2 O 2 process, and the result shows that 300 mg/l of H 2 O 2 is the optimum dosage for the treatment. Saritha et al (2007) compared various AOP for the degradation of 4-chloro-2-nitro phenol, and the result shows that removal rate was higher for the UV/ Fenton process. Bin and Sobera-Made (2012) studied UV, UV/H 2 O 2 and O 3 process for the treatment of antibiotic substance present in the wastewater, and the effective removal of COD and TOC was observed for the O 3 process.…”

The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H 2 O 2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe 2? concentration on Fenton system for the percentage color and chemical oxygen demand removal has been studied. The energy per order was also calculated for the advanced oxidation process. The ozone-photoFenton system has been observed that 100 % color and chemical oxygen demand removal compared with other process studied in the present investigation within 4 h of treatment time. Electrical energy per order has been calculated for all the process and found that ozone-photoFenton shows lesser energy consumption of about 0.01 kWh/m 3 order 1 , for the complete color and chemical oxygen demand removal.
