“…Considering the high organic content of cow manure, it can be concluded that ozonation was quite efficient for the treatment of E. coli HB101. The treatment efficiency that was achieved in a relatively short contact time in this study may be the result of hydroxyl radical generation from the applied ozone because both pH and metal content of the manure were able to catalytically decompose the ozone (Uslu and Balcioglu, 2009a).…”

“…• In this process there were no toxic byproducts but in photolysis (Shaojun 2008), Ozonation (Li 2008 andUslu 2009) and UV/TiO 2 (Zhao 2010), the byproducts were toxic. The biological treatments for OTC removing were not very successful, because of the toxicity of OTC for microorganism and low yield of removing by them (Huang 2011a andArikan 2006).…”

“…The concentration of 1000 mg/L OTC in the photocatalytic process of TiO 2 /UV at pH =7 after 210 min, 88% have been removed (Zhao 2010). In Fenton process, Iron and Hydrogen peroxide in a ratio of 1 to 10, after 120 min 70% of OTC with 100 mg/L initial concentration was removed (Uslu 2009). …”

Pharmaceutical wastewater can be difficult to treat with conventional physical/chemical and biological treatment systems. The presence of antibiotics in sewage selects for resistance markers that are able to spread through the microbial community and as a result, antibiotic resistant bacteria can potentially disseminate their resistance genes widely among members of the endogenous microbial community. The sludge products of urban and rural wastewater treatment plants are increasingly used to fertilize agricultural crops, dispersing unknown amounts of resistance genes and antibiotics that withstand standard sewage treatment. Pharmaceutical wastewater effluents are well known for their difficult elimination by traditional biotreatment methods and their important contribution to environmental pollution due to its fluctuating and recalcitrant nature. OTC is one of the nonbiodegradable antibiotics that makes antibiotic-resistant, so it can make be high risk for environment. NZVI can be a good choice for removal of OTC in aqueous solution. Response surface methodology (RSM) was used to optimize the amounts of NZVI and OTC to be used at pH 3 and under 200 W, UV-A irradiation. The responses were removal percent of absorption at 290 and 348 nm, TOC and COD of OTC. In the optimum condition, Linear model was performed 155 ppm of OTC were removed by 1000 ppm NZVI after 6.5 hours and the removal efficiency of absorption at 290 and 348 nm, TOC and COD were 87, 95, 85 and 89 percent, respectively. In the similar process, there is no organic compound after 14 hours. The parameters ORP, DO and pH were investigated for 6:30 hours to study the type of NZVI reaction in process. In the beginning of reaction, oxidation was the dominant reaction after 3 hours, photo catalytic reaction was remarkable. The mechanism of OTC degradation is proposed by HPLC/ESI-MS and four by products were found. Also the rate constants (first order kinetic chain reaction model) were 0.0099, 0.0021, 0.0010, 0.0049 and 0.0074 min -1 , respectively.

“…Furthermore, the application of ferrate (VI) can improve the removal of nature organic matter or disinfection byproducts (DBPs) precursors (Sharma et al, 2006). There are many processes have been investigated on the degradation of OTC, such as ozone process, Fenton process, UV photolysis, simulated sunlight irradiation (Uslu et al, 2009;Yuan et al, 2011;Chen et al, 2008;Li et al, 2008). However, no study has been reported on the removal of OTC using ferrate (VI).…”

The treatment of oxytetracycline (OTC) in test solutions by ferrate (VI) was investigated aiming to propose the effects of pH, concentration of co-existing ions and humic acid on the OTC removal. Ferrate (VI) can remove 97% OTC (from 1000 µg·l ) on the OTC removal were investigated for the optimal operating conditions. The results showed that Ca 2+ , CO3 2-, PO4 3-could inhibit the OTC degradation and its removal rate decreased from 79, 29, 29% to 70, 19, 19%, for the ion concentration increased from 0.005 mol·l -1 to 0.02 mol·l -1. Mg 2+ and HCO3 -could restrain the reaction carried out at 0.02 mol·l -1 and the removal rate was only 59%, 62%. Al 3+ could increase the removal rate which reach to 100%. Humic acid with concentrations of greater than 10 mg·l -1 could notably inhibit the OTC removal. Regression analysis indicated good fit of the experimental date to the developed model with coefficient of determination (R 2 ) value of 0.9991 and the adjusted R 2 value of 0.9978.
