“…Methylene blue stands in last place with a degradation rate constant two times weaker than that of the congo red, which is, in its turn, two times weaker than that of the yellow drimaren. This values of rate constants for dye degradation by hydroxyl radicals agree with the literature cited values for the degradation of aromatic compounds by hydroxyl radicals which are generally in the order of 10 −9 to 10 −10 L mol −1 s −1 (Ruppert et al 1993). …”

“…However, the advanced oxidation processes (AOPs) that use hydroxyl radicals, a very strong oxidant, provide a convenient method for the treatment of organic pollutants as dyes. Among these treatments, the Fenton's reagent and the photo-oxidation using UV/H 2 O 2 , UV/TiO 2 or UV/H 2 O 2 /Fe 3+ systems (Ruppert et al 1993;Ince 1999;Robert and Malato 2002) showed their effectiveness to eliminate organic compounds dissolved or dispersed in aqueous media.…”

International audienceAn environmentally friendly electrochemical treatment, electro-Fenton process, was applied to the depollution of a synthetic dismissal composed of three dyes, yellow drimaren, congo red and methylene blue, frequently used in textile and dyehouses. Here, we show that those dyes and their mixture are quickly degraded under current controlled electrolysis conditions, leading to an almost complete mineralization. The results show the efficiency of electro-Fenton process to quickly degrade aqueous effluents polluted by synthetic organic dyes

“…Although some homogeneous photo-Fenton systems using Fe ions [20][21][22][23][24][25] feature a merit of powerful degradation of organic compounds, they have a disadvantage of requirement to remove Fe ions from water after water treatment. 9 From a viewpoint of smoothing and recycling usage, or running cost in future water purification plants, a heterogeneous system must be superior to homogenous one.…”

“…Este controle da concentração de peróxido de hidrogênio é fundamental para o processo oxidativo avançado em questão. Alguns estudos relatam que o excesso de peróxido de hidrogênio é prejudicial à eficiência do processo Fenton, uma vez que o peróxido de hidrogênio em excesso consome radicais hidroxila formados e, portanto, diminuem a eficiência do processo (Ruppert et al, 1993). No entanto, os valores de eficiência obtidos na ETE são comparáveis aos resultados obtidos em laboratório por diversos autores, considerando a aplicação do processo Fenton na remoção de fenol.…”

RESUMOEste trabalho descreve o desempenho de um reator Fenton em grande escala usado para remoção de fenol em uma planta de valorização dos resíduos da indústria de papel e celulose. O efluente consiste em óleo vegetal e fenol. A estação de tratamento objetiva tratar 4 m 3 h -1 e é constituída por um pré-tratamento para remoção de óleo, reator Fenton, Flotador de Ar Dissolvido -FAD e uma lagoa de aeração. Para a avaliação da estação de tratamento foram comparadas análises próprias do efluente com análises feitas em laboratório certificado. A eficiência global de remoção de fenol é maior do que 99,7%. Foi demonstrado que a combinação do processo de oxidação avançada com o biológico constitui-se em um sistema de tratamentos interessante a fim de remover contaminantes recalcitrantes.Palavras-chave: efluente, processo oxidativo avançado, reator em larga escala, tall oil. Performance of a Fenton reactor on an industrial scale applied to the removal of phenols in a waste recovery plant from the pulp and paper industry ABSTRACTThis paper describes the performance of a Fenton reactor on an industrial scale applied to the removal of phenols in a waste recovery plant from the pulp and paper industry. The effluent consists of vegetal oil and phenol. The treatment plant is designed to treat 4 m 3 h -1and consists of a pre-treatment for oil removal, a Fenton reactor and an extended aeration tank. Internal and external analyses of the effluent were performed in order to evaluate the
