[Show abstract][Hide abstract]ABSTRACT: The courses of environmental engineering have increasingly become more common in Brazil. In spite of the common legislation that defines the subjects of basic, professional and specific graduation, there has been a variation in the focus given in the list of subjects of these courses, which have been strongly influenced by the vocation of the Institution of Undergraduate Teaching (IES). The objective of this essay is to present the structure, the curricular emphasis and the approaches used by the pedagogic project of the environmental engineering of UNIPINHAL, from Espírito Santo do Pinhal – SP. There are two curricular emphases that guide the course: technology for the environment and environmental planning and managing. These emphases have been given in a way to connect subjects, research, laboratories and extension projects, showing the vocation of the region and of the course, which is strongly agricultural.
[Show abstract][Hide abstract]ABSTRACT: The objective of the present research was to evaluate the efficiency of a slow sand filtration systempreceded of a roughing filtration, using material wich are easy to find in the market, like sand often used incivil constructions and non woven synthetic fabrics, for the improvement of water quality in a small ruralproperty. This efficiency was evaluated analysing some phisical, chemical and biological parameters, liketurbidity, color, pH, dissolved oxigen, temperature, zinc, boro, phosphorous, nitrogen, total colliform andfecal colliform. The influence of slow sand filters and roughing filters interruption in the project efficiencyalso was evaluated; as the use of two filtration rates: 2 and 4 m3/m2.day. The results of the research pointedout to the technic and economic viability of using slow sand filtration for water treatment for smallproperties, as efficiency of roughing filter to attenuate turbidity peaks and color of the raw water. Theintermittent filtration process showed being an interesting operation to recuperate the hydaulics headwithout damag in the quality of effluent.
[Show abstract][Hide abstract]ABSTRACT: The objective of this study was to evaluate the performance of a subsurface flow constructed wetland onthe removal of fish water macronutrients, a experiment was carried out at cimento-amianto box cultivated with Thypha spp on monocultive system. The parameters evaluated were: Nitrogen removal, Phosphors removal, Sulfur removal, Calcium removal, Potassium removal and Magnesium removal. The results showed 36,15% of Nitrogen removal, 43,30% of Phosphors removal, 28,20% of Sulfur removal, 26,30% of Calcium removal, 31,61% of Potassium removal and 16,20% of Magnesium removal. As conclusions, the performance of the system on Nitrogen total removal was smaller whem comparated with other autors; the phosphorous removal was considered satisfactory and the performance of the system on Sulfur, Calcium, Magnesium and Potassium removal was low.
[Show abstract][Hide abstract]ABSTRACT: CREUPI – Centro Regional Universitário de Espírito Santo do Pinhal established its first Environmental Engineering course in February 2000. Since then and despite its recent creation, our teachers and students have become increasingly involved in research and extension-related activities, which has resulted not only in the steadily growing participation of the course in scientific and technical events, but also in services rendered by the course to the community. The main purpose of this article is to report on the course’s research and extension activities and to outline its future trends. The research and extension activities of our environmental engineering course have been backed by the university’s laboratories of Microbiology, Biotechnology, Limnology and Soil, and have focused on issues relating to rural environments, such as the treatment of water and effluents from agriculture, the reuse of industrial residues in agriculture, the recycling of residues, environmental impacts, and the microbiological quality of water in urban and rural environments. The creation of the Freshwater Project in our extension course has introduced a new approach, which involves activities of extension and environmental education with joint community participation.
