14. Estudo da aplicação de UV/FENTON (Fe2+/H2O2) no tratamento de efluentes de laticínios / Study of the Application of UV/Fenton (Fe2+ + H2O2) in the Treatment of Dairy Effluent.
O efluente lácteo é o resíduo obtido no beneficiamento do leite e seus derivados, sendo considerado um passivo de alto poder poluidor. Sem o devido tratamento, quando lançado nos rios compromete a sobrevivência da biota como um todo. O objetivo deste trabalho consistiu em avaliar a eficiência e aplicação do processo Foto-Fenton, seguido por um tratam

15. Caracterização de contaminantes presentes em sistemas de tratamento de esgotos, por cromatografia líquida acoplada à espectrometria de massas tandem em alta resolução
This work shows results on the characterization, by liquid chromatography coupled to high resolution tandem mass spectrometry (LC-IT-TOF-MS) with electrospray ionization, of organic compounds present in raw and treated effluents from a combined sewage treatment systems (upflow anaerobic sludge blanket-trickling filter). The sewage samples were prepared by C1

16. Análise do gerenciamento ambiental nos hospitais de Caxias do Sul - RS
The activities of the elderly health assistance institutions generate tons of hospital residues daily. The efficiency of the health sector is questioned, concerning the management of hospital residues, as an emergent subject in the environmental problematic. Currently we count on management practices and the support of the current laws that are designed with

17. Aerobic biofilms for nitrogen removal in flow cells, submitted to different superficial velocities and loading rates / Biofilmes aeróbios para remoção de nitrogênio em células de fluxo, submetidos a diferentes velocidades superficiais e taxas de carregamento
The post-treatment of anaerobic reactor effluents, such as the Upflow Anaerobic Sludge Blanket (UASB), in most applications, is necessary, since this kind of biological treatment promotes BOD removal ranging from 60 to 75% and it has low efficiency in nitrogen and phosphorous removal. Nitrogen removal is usually carried out in a conventional way through nitr

18. Utilização de sulfeto como doador de elétrons para a desnitrificação autotrófica aplicada ao tratamento de esgoto sanitário / Utilization of sulfide as electron donor in autotrophic denitrification applied to treatment of domestic sewage
The feasibility of autotrophic denitrification of effluent from anaerobic reactor treating domestic sewage using sulfide as electron donor was evaluated. Prior researches reveals sulfide into liquid phase of effluents and biogas can be utilized as electron donor for denitrification. However, information about the interaction between carbon, nitrogen and sulf

19. Cultivo de bactérias redutoras de sulfato (BRS) e sua aplicação na biorremediação de efluentes ácidos contendo metais
Sulfate Reducing Bacteria (SRB) can be used as a promise and attractive biotechnology based alternative to promote passive treatment of industrial effluents. Sulfate is reduced to sulfide while organic matter is oxidized producing carbonate and bicarbonate ions. Treatment efficiency however depends on pH and metals content of the selected effluent and also o

20. CEFALOSPORINAS E SURFACTANTE NÃO-IÔNICO EM EFLUENTE HOSPITALAR: DETERMINAÇÃO, DEGRADAÇÃO POR MEIO DE FOTÓLISE E ELETROCOAGULAÇÃO E IDENTIFICAÇÃO DE SUBPRODUTOS E METABÓLITOS / CEFALOSPORINS AND NON IONIC SURFACTANTS IN HOSPITAL WASTEWATER: DETERMINATION, DEGRADATION BY MEANS OF PHOTOLYSIS AND ELECTROCOAGULATION AND IDENTIFICATION OF BYPRODUCTS AND METABOLITES
The currently incorrect and excessive consumption of pharmaceuticals and surfactants, mainly domestic usage, has become a concern to the scientific community around the world, due to the environmental consequences with regard to the bacterial resistance (characteristic of antibiotics), and alteration of hormonal systems (provoked by the degradation products

21. AnÃlise ecotoxicolÃgica do efluente da indÃstria de beneficiamento da castanha de caju antes e apÃs tratamento em reator aerÃbio inoculado com fungos / Ecotoxicological analysis of the effluent from industry to benefit from the cashew nuts before and after treatment in the aerobic reactor inoculated with fungi
The cashew nut improvement is a very important and well-developed activity in almost all states of northeast Brazil, especially CearÃ. However, there are few studies regarding the contribution of the cashew nut industry to environmental pollution in CearÃ. This industryâs wastewater contains traces of cashew nut shell liquid (CNSL), in which phenols and o

22. Ozonização catalítica do chorume proveniente do antigo aterro controlado da cidade de Guaratinguetá-SP utilizando os íons Fe2+, Fe3+, Zn2+, Mn2+, Ni2+ e Cr3+ / Homogeneous catalytic ozonation of leachate from Guaratinguetá - SP landfill, using the ions Fe2+, Fe3+, Zn2+, Mn2+, Ni2+ e Cr3+
Durante anos, o lixo da cidade de Guaratinguetá foi aterrado e o seu produto recalcitrante não passou por nenhum tratamento físico ou mesmo químico, percolando diretamente sob o aterro. Mesmo tendo sido desativado e transformado em Parque Ecológico, o material depositado no local ao longo dos anos, continuará a ser decomposto por microrganismos e conti

23. Otimização do sistema de tratamento de efluente de indústria de processamento de carnes e derivados / OPTIMIZATION OF WASTEWATER TREATMENT SYSTEM OF PROCESSING MEAT AND MEAT STUFF INDUSTRY
The meat processing industry creates large amount of liquid effluent with high pollutant concentration. Previously to its delivering to the environment it is proclaimed it should be treated and brought to suitable levels for pollutant reduction, according to environmental legal requirements. Such effluents, under several variations on meat and derivates dema

24. Degradation of agricultural solid Wastes by microorganisms isolated from sugarcane bagasse, and its percolated, and of effluents from agri-industry. / Degradação de resíduos sólidos agrícolas por microrganismos isolados de bagaço de cana e seu percolado, e de efluentes de agroindústria.
Brazil occupies a place of prominence in the productive sector, as well as in the exploitation of agricultural waste, from sugar cane. This use is a fairly widespread practice, both for effluents, mainly vinasse, but also for solid residues, such as filter-cake and bagasse from sugar cane. Thus, at the start of the 2005/06 harvest, samples were collected fro
