13. Swine manure digestate treatment using electrocoagulation
ABSTRACT Anaerobic biodigestion is an appropriate alternative for the treatment of swine wastewater due to its biogas generation properties and the possibility of its application as a source of energy for heating or electricity. However, digestate can still contain high levels of turbidity, organic carbon and nutrients and must be correctly managed as a biof

14. Odor from anaerobic digestion of swine slurry: influence of pH, temperature and organic loading
Farm slurry management from storage and/or treatment is the main source of odors from swine production, which are determined by factors such as operational variations (organic loading), cleaning of facilities and animal diet (pH) or environmental conditions (temperature). The aim of this study was to evaluate the influence of pH, temperature and organic load

15. AnSBBR with circulation applied to biohydrogen production treating sucrose based wastewater: effects of organic loading, influent concentration and cycle length
An anaerobic sequencing batch biofilm reactor (AnSBBR) containing immobilized biomass and operating with recirculation of the liquid phase (total liquid volume 4.5 L; treated volume per cycle 1.9 L) was used to treat sucrose-based wastewater at 30 ºC and produce biohydrogen. The influence of applied volumetric organic load was studied by varying the influen

16. Methane production in anaerobic digestion of organic waste from Recife (Brazil) landfill: evaluation in refuse of diferent ages
This work focuses on monitoring the generation of biogas by biochemical methane potential (BMP) assays, commonly used to assess anaerobic biodegradability of solid and liquid wastes under controlled conditions. The experiment employed 5 g of substrate of both refuses (fresh and one-year-old wastes), digested with 250 mL of inoculum in 1 L flasks as bioreacto

17. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

18. Estimativa da produção de biogás em aterros sanitários para a geração de metano / Estimate of biogas production in a sanitary landfill for the generation of methane
O objetivo deste estudo foi medir a emissão de biogás a partir de um aterro monitorado na cidade de Betim, Estado de Minas Gerais, no sudeste do Brasil, e determinar parâmetros para a aplicação de modelos matemáticos para avaliar a produção de metano ea geração de energia possível para o Betim região específica. O estudo foi realizado no aterro

19. Tratamento de Ãgua residuÃria de fecularia em reator anaerÃbio com leito fixo de pedras de calcÃrio dolomÃtico / Starch wastewater treatment in anaerobic reactor containing Dolomitic limestone
The cassava processing for starch or flour production generates some wastewater (manipueira) with high organic load and toxic compounds, which cause environmental degradation. In the western Paranà region, there are several starch factories, so its waste generation is a concern for the correct treatment and disposal. Thus, anaerobic reactors are a cost-effe

20. GeraÃÃo de biogÃs utilizando cama de aviÃrio e manipueira / Biogas Generation Using poultry litter bed and Cassava Water
A procura por energia tÃm se mostrado cada vez maior e para suprir essa demanda à necessÃrio buscar fontes alternativas de energia. O presente trabalho teve como objetivo verificar a produÃÃo de biogÃs atravÃs da mistura da cama de aviÃrio com manipuiera para obtenÃÃo de biogÃs e analisando seus efluentes e verificando a reduÃÃo de carga orgÃni

21. AnÃlise do Fluxo de Gases na Camada de Cobertura do Aterro SanitÃrio Municipal Oeste de Caucaia (ASMOC) / Analysis of gas Flow in covering layer of Municipal Landfill West of Caucaia (ASMOC)
The growing human consumption entails a greater generation of waste, which, in turn, must be properly treated and disposed. The storage of waste in landfills produces gas, which if not managed properly will affect the quality of life. The uncontrolled emissions of these gases cause multiple economic, social and environmental impacts, as due to air pollution

22. Estudo da geração de metano em uma célula de aterro sanitário / Study of the generation of methane in a landfill cell
O presente trabalho objetivou estudar a geração de biogás em uma célula experimental construída no Aterro Sanitário Caieiras (CTR-Caieiras) com o objetivo de obter os parâmetros cinéticos da geração de metano. A célula experimental foi construída com as dimensões de 30 x 35 x 5 m de altura e no centro foi instalado um dreno para captar o biogás

23. Tratamento e reuso do efluente de biodigestores no processo de biodigestão anaeróbia da cama de frango / Treatment and reuse of efluent of digesters in the anaerobic digestion of poultry litter
The anaerobic digestion process contributes as a method of treating poultry litter and energy generation. However, its applicability may cause some counter-intuitive, requiring for dilution to provide a suitable environment for microorganisms active in the anaerobic process. This dilution increases volume and difficulty of disposal of effluent. Thus, the obj

24. Projetos de mecanismo de desenvolvimento limpo (MDL) em aterros sanitários: contribuições das tecnologias ambientais para o desenvolvimento sustentável.
The Kyoto Protocol is regarded as one of the most ambitious global political events on the environment. Through this global environmental governance landmark major industrial nations pledged to cut their emissions of greenhouse gases (GHG) in the atmosphere. To facilitate compliance with emission targets for GHG, three flexibility mechanisms were created. Am
