1. Using the pollutant load concept to assess water quality in an urban river: the case of Carahá River (Lages, Brazil)
Resumo O objetivo deste trabalho foi avaliar a qualidade da água do Rio Carahá no município de Lages (Brasil), utilizando o conceito de carga de poluentes e comparar a representação dos resultados com aquela expressa por meio do índice de qualidade da água. Para este estudo foram selecionados 13 pontos ao longo da calha do rio e realizadas 8 coletas d

2. POTENTIAL OF REDUCTION IN THE EMISSION OF METHANE AND NITROUS OXIDE FROM SWINE WASTEWATER AFTER TREATED BY TWO DIFFERENT SYSTEMS
ABSTRACT Swine wastewater have high pollution load, requiring treatment before its disposal into the environment. Methane (CH4) potentially emitted for such waste is considered 21 times more polluting than Carbon dioxide (CO2), and the nitrous oxide (N2O) is considered 310 times. In this way, projects of the Clean Development Mechanism (CDM) and energy use r

3. Treatment of dairy wastewater with a membrane bioreactor
Among the food industries, the dairy industry is considered to be the most polluting one because of the large volume of wastewater generated and its high organic load. In this study, an aerobic membrane bioreactor (MBR) was used for the treatment of wastewater from a large dairy industry and two hydraulic retention times (HRT), 6 and 8 hours, were evaluated.

4. Potencial poluidor de um laticínio de pequeno porte: um estudo de caso / Polluting potential of a small-dairy industry: a case study
The increasing degradation of the environment has generated global concerns, attracting the attention to environmental problems, with awareness playing a key role in achieving material and economic development as well as a better quality of life. The dairy industry is an important part of the food industry and its contribution to water course pollution is si

5. Produção de biogás, caracterização e aproveitamento agrícola do biofertilizante obtido na digestão da manipueira / Biogas production, characterization and agricultural use of the biofertilizer obtained in the cassava digestion
During the cassava roots processing, large quantities of waste are generated, among which stands out the manipueira, an effluent that has high polluting load, but on the other hand can be used as fertilizer and energy source. In this context, this study aimed to examine the anaerobic digestion of manipueira process, seeking to quantify the biogas produced it

6. Vulnerabilidade e risco à poluiÃÃo do sistema aqÃÃfero â entre Crato e MissÃo Velha, bacia do Araripe, Cearà / Vulnerability and risk to the pollution of the aquifer system - between Crato and MissÃo Velha, Araripe Basin, Brazil
It is increasing in the entire globe, the preoccupation with the environment, where we emphasize in this work the preoccupation with the vulnerability and risk to pollution of Medium Aquifer System in the region between Crato and MissÃo Velha towns, Cariri Valley, Araripe Basin, CearÃ. The studied area is located at the south portion of Cearà State, in th

7. Caracterização do efluente líquido no processo de beneficiamento do índigo têxtil
The great diversity of the textile industries activities causes the formation of wastewaters with high complex characteristics during the productive process, according to the industrial process used. The principal aim of the present work is the characterization of the wastewater from the textile industry that process the indigo, located in the Industrial Dis

8. Remoção de cor de efluente de tituraria em leito poroso / Color removal from textile wastewater in porous bed
Textile industry processes have one of the greatest wastewater productions, increasing quantitatively and qualitatively polluting load discharge in surface water. Colored water result of their process generate great environment damages once they not only reduce the water quality but also block sun light from penetrating in the aquatic ecosystem harming biota

9. AnÃlise energÃtica experimental e estudo da viabilidade econÃmica de um grupo gerador de 30 kWe A gÃs natural em diferentes nÃveis e tipos de cargas elÃtricas
Due to the lack of investment in the Brazilian electricity sector, together with the increment of the economy, there is a great possibility of new electricity rationing in 2007. This energy shortage imposes that the companies, which do not intend to have a reduction in their production capacity, supply their own electricity. One of the main options is the el

10. Reduction of dye in effluent of dyeing process of industrial laundries for adsorption in clay / Redução de corante em efluente de processo de tingimento de lavanderias industriais por adsorção em argila
The textile industries constitute factor of great importance in the Brazilian economy and are grouped in three main staple fiber categories: fabrics of cotton, woolen and synthetic. The environment impact provoked by the sector, the generation of effluent liquids if constitutes in a representative parameter as potentially polluting factor. Moreover, it is on

11. VULNERABILIDADE NATURAL DE AQÜÍFEROS E POTENCIAL DE POLUIÇÃO DAS ÁGUAS SUBTERRÂNEAS / NATURAL VULNERABILITY OF AQUIFERS AND POTENTIAL OF POLLUTION OF THE GROUNDWATERS
A widespread attitude exists of underestimating the risks of pollution of the groundwaters that it opposes to the growth of its use; this situation increases its risk of contamination. Like this, the work had as general objective to determine areas susceptible to the contamination of the groundwaters in Santa Maria s Geographical Micro region; and as specifi
