1. Degradación de un efluente textil real asistida por Fe/PVA y materiales residuales magnéticos
ABSTRACT Organic compounds present on industrial wastes are mostly resistant to conventional biological and chemical treatments. Textile industry has presented several environmental problems mainly related to the use and management of water resources. It has a high consumption of potable and underground water in its processes. These wastewaters are one of th

2. Degradação do antibiótico ciprofloxacina em solução aquosa por meio de processo oxidativo avançado baseado em ozônio. / Degradation of the antibiotic ciprofloxacin in aqueous solution by the advanced oxidation process based on ozone.
Os tratamentos convencionais de efluentes em geral não são eficientes para a degradação de compostos persistentes como os fármacos. Neste trabalho, estuda-se o tratamento de soluções aquosas contendo o antibiótico ciprofloxacina (CIP) por meio de processo oxidativo avançado baseado em ozônio. Para tanto, foram realizados experimentos em semi-batela

4. Identificação dos produtos de degradação química/eletroquímica do herbicida ametrina / Identification of degration products of chemical/electrochemical herbicide ametrine
In this study the identification of degradation products ametrina (AME), pesticides used on a large scale in the sugar industry. The improvement in the treatment of environmental conditions is of paramount importance to the agricultural regions, since the contamination of soil and groundwater contamination is almost inevitable. In relation to industries prod

5. Performance of coupling an activated sludge reactor with heterogeneous photocatalysis (TiO2/UV) for removing the color of an industrial wastewater / Desempenho do acoplamento de um reator de lodo ativado à fotocatálise heterogênea (TiO2/UV) no descoramento de um efluente industrial
Generally, wastewaters can be easily treated by biological reactors with a good efficiency regarding organic matter removal. However, the process can be impaired in the presence of compounds that are toxic or have low biodegradability. Advanced Oxidation Processes (AOPs) may be a choice to oxidize these compounds and minimize their toxicity and/or increase b

7. Degradation of 2-hydroxybenzoic acid by advanced oxidation processes
In this study, advanced oxidation processes (AOPs) such as the UV/H2O2 and Fenton processes were investigated for the degradation of 2-hydroxybenzoic acid (2-HBA) in lab-scale experiments. Different [H2O2]/[2-HBA] molar ratios and pH values were used in order to establish the most favorable experimental conditions for the Fenton process. For comparison purpo

8. Integration of microbiological treatment with immobilized cells and emerging (Advanced Oxidation Process) technologies for wastewater treatment generated in the textile industry. / Integração do tratamento microbiológico com células imobilizadas e tecnologias emergentes (Processos Oxidativos Avançados) para o tratamento de efluentes gerados na indústria têxtil.
The integration of different treatment processes in the degradation of textile wastewater was evaluated using precipitation technique, advanced oxidation processes (AOP) and aerobic biological treatment. AOPs (Ozone/UV and reagent of Fenton/UV) were evaluated in batch experiments according to a factorial planning L18 (Tagushi Method) in function of the flow

9. Tratamento de efluentes da indústria de processamento de carnes utilizando flotação por ar dissolvido e processos de oxidação avançada
The use of wastewater treatment processes with high efficiency of organic matter removal is considered one of the most important steps to achieve lower pollution loads in meat processing industries. As a primary treatment, dissolved air flotation processes (DAF) using coagulation-flocculation are generally applied. Additionally, the utilization of high effic

10. Degradação de fármacos residuais por processos oxidativos avançados
The concern about aquatic ecosystems and the potential risk of drinking water contamination by pharmaceuticals have stimulated the study of processes for the efficient degradation of these contaminants, since the conventional treatment have been inefficient on that purpose. The advanced oxidation processes (AOPs) appear as viable alternatives due to their ef
