2. Biohydrogen production from cassava wastewater in an anaerobic fluidized bed reactor
The effect of hydraulic retention time (HRT) and organic loading rate (OLR) on biological hydrogen production was assessed using an anaerobic fluidized bed reactor fed with cassava wastewater. The HRT of this reactor ranged from 8 to 1 h (28 to 161 kg COD/m³-d). The inoculum was obtained from a facultative pond sludge derived from swine wastewater treatment

3. Características físicas, químicas e microbiológicas do lodo das lagoas da ETA Gramame
O efeito da disposição inadequada, dos resíduos sólidos, gerados no processo de tratamento de água, no meio ambiente tem-se mostrado ser extremamente danoso, uma vez que os produtos químicos utilizados no referido processo são prejudiciais quando lançados "in natura" em corpos aquáticos, pois pode causar danos ao mesmo. Esta dissertação foi desenv

4. Bacterial biodiversity from an anaerobic up flow bioreactor with ANAMMOX activity inoculated with swine sludge
The present study aimed to describe the bacterial community present at an anaerobic up flow bioreactor with ANAMMOX activity, inoculated with the sludge from the anaerobic pond of a swine slurry treatment system. The description was based on the molecular DNA techniques using primers for amplification of complete 16S rRNA gene and also new primers to amplify

5. TiO2 photocatalytic inactivation under simulated solar light of bacterial consortia in domestic wastewaters previously treated by UASB, duckweed and facultative ponds
In this work, TiO2 photocatalysis was used to disinfect domestic wastewaters previously treated by different biological treatment systems: Upward-flow Anaerobic Sludge Blanket (UASB), facultative pond, and duckweed pond. The microorganisms monitored were E. coli, total coliforms, Shigella species, and Salmonella species. Photocatalytic experiments were carri

6. Remoção de lodo de lagoa facultativa : avaliação quantitativa e qualitativa do lodo acumulado e seu acondicionamento em BAG / Facultative pond removal sludge : quantitative and qualitative assessment of accumulated sludge and its packing in BAG
Estudou-se o sistema de remoção de lodo de lagoa de estabilização, o desaguamento e acondicionamento do lodo pelo uso de BAG, bem como a redução da viabilidade de ovos de helmintos, coliformes, Salmonellas e teor de sólidos em função do tempo de acondicionamento. Entre várias opções para a retirada, adensamento e desaguamento do lodo de lagoa, a

7. Remoção de nitrogênio de lixiviado de aterros de resíduos sólidos urbanos empregando sistema de lodos ativados, composto por reator anóxico e aeróbio em série
The disposition of solid residues in landfills, when projected, built and operated according to the technical norms it is a safe method of disposition. However it happens the generation of having leachate, that is the liquid that results together of the decomposition of the solid residues with the water that reaches the layer of residues. In leachate they ar

8. Dinâmica de Sedimentação de Lodo em Lagoas de Estabilização / Sludge Sedimentation Dynamics in Stabilization Ponds
Stabilization ponds are an effective sewage treatment alternative for the climatic conditions prevailing in Brazil. In the present work, a primary facultative pond was studied, in the city of Natal, Rio Grande do Norte, Northeast Brazil. The aim of this study was to evaluate the sedimentation dynamics in the facultative pond. The pond was divided in three se

9. Avaliação da eficiência da remoção de matéria orgânica e microbiológica de três sistemas de lagoas de estabilização em série na Grande Natal-RN: Beira Rio, Jardim Lola I e Jardim Lola II
Waste stabilization ponds are the main technology in use for domestic sewage treatment in Rio Grande do Norte State (RN), northeast Brazil. The are around 80 systems, constructed mainly by municipal city halls, being series comprised by a primary facultative pond followed by two maturation ponds the most used configuration. Due to problems related with the p

10. ProduÃÃo de biogÃs no tratamento dos efluentes lÃquidos de Coffea arabica L. em reator UASB para o potencial aproveitamento na secagem do cafà / Biogas production in the treatment of Coffea arabica L. wastewaters in UASB reactor for the potential use in the coffee drying.
This work had the purpose of studying the biogas production in the treatment of the wet processing coffee wastewaters (ARC) in an anaerobic treatment system in laboratorial scale. The system used was composed of an acidification and equalization tank (TAE), a heat-exchanging, an upflow anaerobic sludge blanket reactor (UASB), a facultative aerated pond (LAF)

11. A decision making model for choosing sewage treatment systems / Modelo para tomada de decisão na escolha de sistema de tratamento de esgoto sanitário
The selection of the wastewater treatment system to be installed in a city can be a difficult decision, once several variables interfere in its cost and in its environmental quality. This study intends to show the possibility of using techniques of decision analysis to select the wastewater treatment system in an ecological and economical way, as decision tr

12. Mechanisms and pathways of aniline elimination from aquatic environments.
The fate of aniline, a representative of arylamine pollutants derived from the manufacture of dyes, coal liquefaction, and pesticide degradation, was comprehensively evaluated by use of unpolluted and polluted pond water as model environments. Evaporation plus autoxidation proved to be minor elimination mechanisms, removing ca. 1% of the added aniline per da
