1. Use of Coffee Capsules as Support Material in Upflow Anaerobic Fixed Bed Reactors
Abstract The aim of this work is to evaluate the performance of upflow anaerobic fixed bed reactors filled with espresso coffee capsules to treat sanitary sewage. Three reactors (R1, R2 and R3) were constructed in blue PVC pipes measuring 30 cm height and 150 mm diameter and filled with coffee capsules made of aluminum and plastic. The sewage from the pre-tr

2. Reforested soil under drip irrigation with treated wastewater from poultry slaughterhouse
RESUMO A disposição de efluentes tratados sobre o solo pode ser considerada o principal destino final de águas residuárias no Brasil. Embora possa promover melhorias em relação a alguns atributos do solo, esta prática precisa ser monitorada para garantir que os impactos ambientais não sejam negativos. Assim, objetivou-se com este trabalho avaliar os

3. Reestruturação na forma do tratamento de efluentes têxteis: uma proposta embasada em fundamentos teóricos
Resumo As indústrias têxteis utilizam grandes quantidades de água nos processos de tingimento e beneficiamento das fibras, gerando volumes elevados de efluentes contendo corantes, surfactantes, íons inorgânicos, agentes umectantes, entre outros. O principal impacto ambiental desses efluentes está relacionado com a absorção de luz no meio aquático,

4. Adaptation of domestic effluent for agricultural reuse by biological, physical treatment and disinfection by ultraviolet radiation
Resumo O reúso de efluente doméstico é uma alternativa para a agricultura irrigada em situações de reduzida disponibilidade de água. No entanto, como é comum a presença de patógenos em águas residuárias, torna-se necessário um processo de desinfecção previamente à sua utilização. Com o desenvolvimento da pesquisa, avaliou-se a viabilidade sa

5. Soil Quality after Six Years of Paper Mill Industrial Wastewater Application
ABSTRACT The application of wastewater to irrigate soils may be an attractive option for paper mills, especially when the effluents can also provide nutrients to plants. Since there could be negative environmental effects, such activity must be preceded by a thorough evaluation of the consequences. The changes in soil quality of a Neossolo Flúvico Distrófi

6. Genotoxic evaluation of the River Paranaíba hydrographic basin in Monte Carmelo, MG, Brazil, by the Tradescantia micronucleus
Abstract Pollutants have adverse effects on human health and on other organisms that inhabit or use water resources. The aim of the present study was to assess the environmental quality of three watercourses in Monte Carmelo, MG, Brazil, using the micronucleus test on Tradescantia. For each treatment, 15 plants were exposed to water samples for 24 h. The con

7. Investigation of the Environmental Transport of Human Pharmaceuticals to Surface Water: A Case Study of Persistence of Pharmaceuticals in Effluent of Sewage Treatment Plants and Hospitals in Malaysia
The present work reports the occurrence and monitoring of 11 pharmaceuticals (i.e., caffeine, prazosin, enalapril, carbamazepine, nifedipine, gliclazide, levonorgestrel, simvastatin, hydrochlorothiazide, diclofenac-Na and mefenamic acid) in surface water and in the influent and effluent of sewage treatment plants (STPs) and hospitals (HSPs). A total of 105 w

8. Microalgae population dynamics in photobioreactors with secondary sewage effluent as culture medium
Nitrogen and phosphorus present in sewage can be used for microalgae growth, possibiliting cost reduction in the production of microalgae at the same time that it decreases the eutrophication potential of the effluent. This research aimed at monitoring the native community of microalgae and coliform bacteria in a secondary effluent from anaerobic municipal s

9. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct

10. 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

11. Estudo da tratabilidade de efluente de reator anaeróbio e lixiviado de aterro sanitário utilizando o processo de lodos ativados / Treatability of the anaerobic effluent and landfill leachate using activated sludge process
Embora em alguns países como os europeus, o aterro sanitário como forma de disposição final de Resíduos Sólidos venha perdendo espaço, entre nós essa técnica é ainda largamente empregada. O lixiviado gerado nos aterros sanitários apresenta grande potencial poluidor, devido à presença de matéria orgânica, rica em substâncias húmicas e matéri

12. Impactos ambientais da disposição de resíduos sólidos urbanos no solo e na água superficial em três municípios de Minas Gerais
The study was conducted in the landfill area of Campo Belo, the landfilling of Santo Antonio do Amparo and the dump closed from Elói Mendes, located in southern Minas Gerais, to evaluate the environmental impacts of different types of disposal Municipal Solid Waste under field conditions on the surface water and soil. For the assessment of impacts on surfac
