This study analyses the colour acquired by oxidizing paracetamol aqueous samples through the combined US/H2O2 technology. When operating with only the action of the waves [US]=1.0 kWh/mmol C8H9NO2, the water acquires progressively hue according to a ratio of 0.0004 AU/min, with a degradation output...Read more
Comparison of caffeine oxidation by Fenton reagent in combination with UV light and ultrasound waves
(Corresponding) Villota N., Lomas J., Ferreiro C., Lombraña J.
Topic:
Advanced oxidation processes
The oxidation of aqueous caffeine solutions ([Ca]0=100.0 mg L-1) was analysed, operating at pH=3.0 and 25ºC using different AOPs, which combine the Fenton reagent ([H2O2]0=15.0 mM and [Fe2+]0=20.0 mg L-1) with low power UV light (15W,), medium (150W), and high (720 W). The Fenton reagent, combined...Read more
Toxicity study of Norfloxacin degradation by advanced oxidative process
Costa B., Cordeiro S., Schweizer Y., Weber A., Haas P., de Oliveira L., Ethur E., (Corresponding) Hoehne L.
Topic:
Advanced oxidation processes
Advanced oxidative processes (AOPs) are promising techniques that have been developed to treat and remove these organic contaminants in surface waters and effluents. The objective of this work was to evaluate the toxicity of products generated from UV/H2O2 degradation of solutions containing 5 µg/...Read more
Degradation of refractory compounds in industrial wastewaters by advanced technologies based on electrochemical and photochemical oxidation
Petsi P., Sarasidis V., (Corresponding) Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
Results are presented of a systematic experimental investigation aiming to eliminate refractory organics from industrial effluents, of high and non-biodegradable organic load, by two Advanced Oxidation Processes (AOPs). Bench scale experiments were performed with real wastewater samples collected...Read more
Preliminary Research on Removal of Organic Substances Contained in Wastewater from Plastic Lenses Production
(Corresponding) Umiejewska K., Różycki M.
Topic:
Advanced oxidation processes
More than 80 percent of all eyeglasses worn today have plastic lenses. Plastic lenses made of polycarbonate discs are created through the process of machining which requires the use of a coolant. During the production process, the rotating disc and blade are poured with a mixture of water and...Read more
SELECTED APPLICATIONS of CAVITATION BASED ADVANCED OXIDATION PROCESSES (AOPs) for TREATMENT of WATER and INDUSTRIAL EFFUENTS
Fedorov K., Cako E., (Corresponding) Boczkaj G.
Topic:
Advanced oxidation processes
Cavitation phenomenon was effectively applied for enhancement of Advanced Oxidation Processes (AOPs) effectiveness. Main applications are focused on treatment of water as well as industrial effluents [1-2]. Cavitation phenomenon can be generated in the liquid by intentionally formed differences in...Read more
Degradation of cytostatic drugs in water by ozonation
(Corresponding) Garcia-Costa A., Gouveia T., Pereira M., Silva A., Alves A., Madeira L., Santos M.
Topic:
Advanced oxidation processes
This work presents the degradation of five cytostatics found in Portuguese WWTP effluents: bicalutamide (BICA), capecitabine (CAP), cyclophosphamide (CYC), ifosfamide (IFO) and mycophenolic acid (MPA) using non-catalytic ozonation. Experiments were performed with 1 µM of each cytostatic at pH: 7.3...Read more

Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids
(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...Read more
Influence of the addition of M2+ (M: Co, Cu, Zn) on the properties and activity of W-TiO2 and Mo-TiO2 photocatalysts for water remediation
Mergenbayeva S., (Corresponding) Poulopoulos S., Grilla E., Vakros J., Mantzavinos D.
Topic:
Advanced oxidation processes
In this study, ternary systems of M1M2TiO2 (M1:Co, Cu, Zn) M2 (WO3, MoO3) were prepared and tested for the photocatalytic degradation of sulfamethoxazole. It was found that W-oxo species can be used without significant alteration of the TiO2 activity, while only Cu is a possible candidate for the...Read more
Destruction of anthracene and phenanthrene using PDS/UV, one of advanced oxidation processes in terms of degree of destruction and by-products.
(Corresponding) Nowakowski M., Czyż E., Wolski R., Andrzejewski P.
Topic:
Advanced oxidation processes
Anthracene and phenanthrene belong to a group of persistent environmental contaminants called PAHs. Evaluation of the structural of two selected PAHs i.e. anthracene and phenanthrene on its resistance to destruction by UV-activated PDS was the aim of this study. Authors focused on two aspects of...Read more
