1. Sistema integrado com microalgas e wetland construído de fluxo vertical no tratamento de efluentes urbanos
RESUMO O sistema integrado com microalgas (MA) e wetland construído de fluxo vertical (wetland construído pós-microalgas - WCPMA) foi aplicado para a realização de ensaios de tratamento de efluentes no campus da Universidade de Santa Cruz do Sul, no Rio Grande do Sul (UNISC-RS). Águas negras e amarelas foram alimentadas para esse sistema em regime de b

2. INFLUENCE OF SUBSTRATE AND SPECIES ARRANGEMENT OF CULTIVATED GRASSES ON THE EFFICIENCY OF HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLANDS
ABSTRACT We aimed to evaluate the efficiency of six different horizontal subsurface flow constructed wetlands (HSSF-CWs), with different substrates (gravel and crushed PET bottles), which also varied in relation to the presence and arrangement of plant species (elephant grass and Tifton 85 bermudagrass) in the removal of pollutants from a bulk milk cooling t

4. Influência da relação C/N na produção de hidrogênio em reator anaeróbio de leito fixo / Influence of the carbon/nitrogen ratio on the hydrogen production in a fixed-bed anaerobic reactor
This study evaluated the effect of the carbon/nitrogen (C/N) ratio on the hydrogen production from a sucrose-based synthetic wastewater. Up-flow fixed-bed anaerobic reactors with recycled low-density polyethylene for biomass attachment, were operated at 25ºC and with a 2 hours time of hydraulic detention. Several C/Nrelationship were studied (40, 90, 140 an

5. Partially aerated attached biomass bed reactor applied to treatment sanitary sewage treatment / Reator com leito de biomassa aderida aerado parcialmente aplicado ao tratamento de esgoto sanitário
This work aimed to evaluate the performance of a full scale up-flow attached biomass bed reactor (159 M POT.3) and with continuous aeration at 7 m above bottom of the reactor to sanitary sewage treatment. The bed of the reactor was constituted for activated granular carbon, anthracite carbon and sand. The work was divided into two stages. In the first stage,

7. Remoção de compostos orgânicos causadores de gosto e odor em águas de abastecimento em sistemas pós-filtros adsorvedores de carvão ativado granular. / Removal of taste and odor producing organic substances in water supply in post-filter granular activated carbon adsorber systems.
The main purpose of this research was to study the performance of granular activated carbon post filter adsorbers made of bituminous coal and vegetal coal (coconut), regarding, mainly, removal of 2-methylisoborneol and trans-1,10-dimethyltrans- 9-decalol. The experimental researches were conducted in the water treatment plant Alto da Boa Vista, using four pi

8. Remoção de carbono e nitrogênio em reator de leito móvel submetido à aeração intermitente / Nitrogen and carbon removal in moving bed reactor operated under intermittent aeration
The operating conditions for the combined removal of nitrogen and organic matter in moving- bed biological reactor were investigated. Two bench-scale reactors, two liters each, were operated under intermittent aeration and continuously fed with synthetic wastewater containing ammonia nitrogen (90 to 110 mg/L) and molasses as organic carbon source (COD of 450

9. Domestic wastewater post-treatment using ornamental plants : Constructed-Wetlands with gravel and bamboo as substrate / Plantas ornamentais no pos-tratamento de efluentes sanitarios : wetlands-construidos utilizando brita e bambu como suporte
Anaerobic reactor s effluent post-treatment systems make possible the improvement of anaerobic-treated wastewater characteristics in diverse conditions in a simple way. This posttreatment design flexibility will be able to support small communities to have better environmental conditions even if they did not have a traditional wastewater plant previously. Th

11. Comportamento de variáveis físicas, químicas e da eficiência de sistemas de lagoas de estabilização em ambiente tropical (Vale do Ribeira de Iguape, SP) / Behavior of physical, chemical variable and efficiency of systems composed by stabilization ponds in tropical environment (Vale Ribeira de Iguape, SP, Brazil)
As lagoas de estabilização compõem sistemas de tratamento de águas residuárias sujeitos à variação de eficiência decorrente, dentre outros fatores, das variações climáticas. A variação de eficiência e da estratificação em lagoas de estabilização, localizadas em ambiente subtropical, em diferentes épocas do ano, foi o principal objetivo de
