BACKGROUND This study aims at evaluating the degradation of the antibiotic ciprofloxacin (CIP) in urban wastewater effluents using a UV‐C‐driven oxidation processes in the presence of hydrogen peroxide. Under the optimum experimental conditions, the phytotoxicity and ecotoxicity of the treated samples were investigated against one plant species (Sinapis alba) and a crustacean (Daphnia magna), respectively. The efficiency of the process to remove E. coli and ciprofloxacin‐resistant E. coli was also assessed. RESULTS Complete degradation of CIP was achieved within 15 min of treatment under the optimum concentration of the oxidant ([H2O2] = 10 mg L−1). The degradation rate of the antibiotic fitted pseudo‐first‐order kinetics. An increase in both shoot inhibition and root inhibition was observed, until 60 min of treatment, beyond which, the phytotoxic effect was eliminated. The results demonstrated the ability of the UV‐C process to reduce the toxicity towards D. magna by 40%, comparatively, to the untreated wastewater. The inactivation of E. coli and CIP‐resistant E. coli was achieved within 2 min of treatment. CONCLUSIONS The UV‐C/H2O2 process was successfully applied for the removal of CIP at low environmental concentration level. The treatment process was able to achieve a significant reduction of phyto‐ and eco‐toxic effects, as well as E. coli harbouring resistance to CIP. © 2016 Society of Chemical Industry

“…The research carried out by Tran et al [27] identified the levels of the operating parameters at which IBU could be degraded by 65% through a sono-electrolytic process under controlled conditions in synthetic water, using a statistical optimization procedure. These same conditions were evaluated with sewage from a municipal treatment plant, with organic and inorganic compounds, as well as microbial load, which was doped with a specific concentration of IBU.…”

Emerging pollutants are compounds of increased environmental importance and, as such there is interest among researchers in the evaluation of their presence, continuity and elimination in different environmental matrices. The present work reviews the available scientific data on the degradation of emerging pollutants, mainly pharmaceuticals, through ultrasound, as an advanced oxidation process (AOP). This study analyzes the influence of several parameters, such as the nature of the pollutant, the ultrasonic frequency, the electrical power, the pH, the constituents of the matrix and the temperature of the solution on the efficiency of this AOP through researches previously reported in the literature. Additionally, it informs on the application of the referred process alone and/or in combination with other AOPs focusing on the treatment of domestic and industrial wastewaters containing emerging pollutants, mainly pharmaceuticals, as well as on the economic costs associated with and the future perspectives that make ultrasound a possible candidate to solve the problem of water pollution by these emerging pollutants.
