“…There, those radicals react with the pollutant molecules and more specifically near the interface. Méndez-Arriaga et al (2008) gradually added quantities of H 2 O 2 equivalent to those produced by sonolysis in a solution of ibuprofen, mechanical stirred and in the absence of ultrasound. They found that there was no degradation of the pollutant, so hydrogen peroxide is not responsible for the ibuprofen sonochemical degradation, but the…”

Sonochemical degradation at 278 kHz of naphthol blue black (NBB, a diazo dye widely used in the textile and soap industries) has been investigated. The effects of different parameters and the influence of mineral matrix (bicarbonates ions and phosphates ions) on its sonodegradation have been evaluated. The influence of parameters linked to the pollutant (concentration: 0.50-97.32 lmol L -1 ), to the technique (power: 20-100 W) and to the natural medium (pH 3-10.8; bicarbonate ions; phosphate ions) has been studied. The decolourisation rate of NBB increases when substrate concentration or ultrasound power increases. Bicarbonate ions at natural medium concentration (2.97 mmol L -1 ) have a positive influence for low pollutant concentration (0.5-2.0 lmol L -1 ), due to carbonate radicals. Phosphate ions may also improve the kinetics, but this effect depends on the pH domains. Furthermore, acid pH (pH 3) has a positive effect for high pollutant concentration, whereas basic pH (pH 10.8) has a positive influence at low pollutant concentration.

“…The use of O 3 /US improves the COD removal efficiency by 19.4 % compared to the use of ozone alone under similar optimal conditions. Parameters such as US power, dissolved gas, pH, and initial concentration of ibuprofen (IBP) were studied in [15], in ultrasonic treatment (300 kHz). US removed 30 to 98 % of IBP within 30 minutes.…”

“…1, the configuration permits the sequential treatment of the synthetic wastewater; US/photo-Fenton treatment was taking place (or vice versa). The same configuration was used in one of our previous works, (used in [29], similar to the set-up used by Mendez-Arriaga et al, [34]), synthetic wastewater from a cylindrical double-wall glass vessel (400 mL) was pumped by a peristaltic pump through three glass reactors (diameter 3.8 cm, effective irradiation surface 214.8 cm 2 ), connected in series, of total volume 230 mL. Temperature was regulated by water recirculating around the reactor and connected to a thermostat.…”

a b s t r a c tIn this study, we attempt for the first time to couple sonication and photo-Fenton for bacterial inactivation of secondary treated effluent. Synthetic wastewater was subjected to sequential high-frequency/low power sonication, followed by mild photo-Fenton treatment, under a solar simulator. It was followed by the assessment of the contribution of each component of the process (Fenton, US, hv) towards the removal rate and the long-term survival; sunlight greatly improved the treatment efficiency, with the coupled process being the only one to yield total inactivation within the 4-h period of treatment. The short-term beneficial disinfecting action of US and its detrimental effect on bacterial survival in long term, as well as the impact of light addition were also revealed. Finally, an investigation on the operational parameters of the process was performed, to investigate possible improvement and/or limitations of the coupled treatment; 3 levels of each parameter involved (hydraulic, environmental, US and Fenton) were tested. Only H 2 O 2 increased improved the process significantly, but the action mode of the joint process indicated potential cost-effective solutions towards the implementation of this method.
