1. Constructed wetlands as post treatment of a decanter digester followed by an anaerobic filter
Resumo Com a crescente expansão das Instituições de Ensino Superior (IES), aumentam-se a quantidade de águas residuais, quando a mesma é lançada sem tratamento ou com tratamento ineficiente contribuem de maneira significativa para poluição dos recursos hídricos. Neste contexto, o objetivo deste trabalho foi avaliar o desempenho de Wetlands Construí

2. ECONOMIC AND FINANCIAL VIABILITY OF DIGESTER USE IN CATTLE CONFINEMENT FOR BEEF
ABSTRACT This research analyzes the economic and financial feasibility of implementing a biodigester for confinement of beef cattle on a farm located in the State of São Paulo, through the approach of discounted cash flow. The anaerobic digestion technology arouses interest, due to its advantages with the generation of electricity and the pollution reductio

3. The Addition of Hatchery Liquid Waste to Dairy Manure Improves Anaerobic Digestion
ABSTRACT The objective of this study was to determine the optimal inclusion level of liquid egg hatchery waste for the anaerobic co-digestion of dairy cattle manure. A completely randomized experimental was applied, with seven treatments (liquid hatchery waste to cattle manure ratios of0: 100, 5:95, 10:90, 15:85, 20:80, 25:75 and 30:70), with five replicates

4. Reasons for the non-use of the biodigestors in swine farms in Marechal Candido Rondon, PR / RazÃes pela nÃo utilizaÃÃo de biodigestores em granjas suinÃcolas em Marechal CÃndido Rondon â PR
The actual economic model takes the society to exploit the natural resources in an inadequate way, besides generating anthrop systems which are not always in concordance with nature. The swine culture is one of these systems, which needs some policies and actions in order to give the activity some sustainability. This research aimed at identifying the reason

5. BIOGRÂNULOS AERÓBICOS EM REATOR SEQÜENCIAL EM BATELADA PARA O TRATAMENTO DE EFLUENTE DE BIODIGESTOR PROVENIENTE DA SUINOCULTURA / AEROBIC BIOGRANULES IN SEQUENTIAL BATCH REACTOR FOR THE TREATMENT OF ANAEROBIC DIGESTER EFFLUENT FROM THE PIGGISH
A fermentação dos dejetos de suínos em biodigestores vem sendo recomendada para o aproveitamento energético do metano (CH4) produzido, diminuindo assim a emissão desse gás de efeito estufa para a atmosfera. Entretanto, a água residual (efluente de biodigestor), se despejada em cursos dágua, pode causar poluição pois apresenta, ainda, Demanda Quími

6. Produção de forragem verde em sistema hidropônico usando esgoto tratado
In the urban areas of the cities a larger problem of destiny of effluents of the treatment stations is verified due to the junction of the sewages in great volumes. This way the hidroponic cultive becomes important, for your intensive characteristic, as alternative of reuse. This work presents as objective the improvement of the relation hidric-nutritious of

7. Biodigestão anaeróbia dos resíduos sólidos urbanos: um panorama tecnológico atual / Anaerobic Digestion of Urban Solid Residues: A Current Technological Panorama
This paper presents a comprehensive and updated view of technologies used in anaerobic digestion (AD) for solid waste treatment. A review of literature and a theoretical analysis of relevant information are carried out for this purpose. The evolution of discussions about environmental issues, the work developed by The United Nations, the Earths climatic syst

8. Practical Method for Detecting Poliovirus in Anaerobic Digester Sludge
A method has been developed which permits reliable detection of low numbers of poliovirus infective units in anaerobic digester sludge and dewatered composted sludge.

9. Medium for the Enumeration and Isolation of Bacteria from a Swine Waste Digester
A habitat-simulating medium was developed for the enumeration and isolation of bacteria from a swine waste digester. A roll tube medium with growth factors for strict anaerobes from previously studied anaerobic ecosystems was used to evaluate the effects of deletion, addition, or level of digester fluid, digester fluid treated with acid or base, rumen fluid,

10. Identification of para-Cresol as a Growth Factor for Methanoplanus endosymbiosus
Growth of the methanogenic bacterium Methanoplanus endosymbiosus is dependent on the presence of ruminal fluid. Ruminal fluid could be replaced by the eluate of a rumen-derived anaerobic digester. From the eluate of the digester, a growth-stimulatory component was purified and identified as p-cresol. Authentic p-cresol supported a half-maximal growth rate of

11. Isolation and Characterization of Xylan-Degrading Strains of Butyrivibrio fibrisolvens from a Napier Grass-Fed Anaerobic Digester †
Six new xylanolytic bacterial strains have been isolated from a Napier grass-fed anaerobic digester. These strains were identified as Butyrivibrio fibrisolvens and were similar in many respects to ruminal isolates described previously. The new isolates exhibited a high degree of DNA homology with several ruminal strains of B. fibrisolvens. Xylan or xylose wa

12. Characterization of Bacteria from a Swine Manure Digester †
One-hundred thirty bacteria isolated from a swine manure digester were predominately gram-positive anaerobes which were tentatively classified into the following genera: Peptostreptococcus, Eubacterium, Bacteroides, Lactobacillus, Peptococcus, Clostridium, and Streptococcus plus two unidentified groups. The major fermentation products formed by these organis
