Adsorção do corante luganil azul por espuma de poliuretano

The industrial development has created many environmental problems that can be observed through the changes in air, soil and water. The pollution of water bodies with compounds present in textile effluents cause beyond the visual pollution, changes in biological cycles, mainly by changing the process of photosynthesis. Due to these environmental implications it is necessary a treatment of livestock manure. The process of adsorption of the dye is a technique that has been successfully employed for effective removal of the color of the effluent. The purpose of this study was to investigate the application of a polyurethane foam plant of castor oil as an alternative adsorbent for removal of dyes in textile effluents. The study was conducted with the dye “luganil azul”, as adsorbent and the foam in a flexible manner and sprayed. It also investigated the influence of pH on the adsorption dye. The kinetic data were obtained, noting that the pH influence on adsorption. Adsorption isotherms of the dye in aqueous solution using the foam in a flexible manner also were determined experimentally.

Contaminação das águas subterrâneas por resíduos de postos de combustíveis: uma abordagem no município de Rio Claro

The contamination of underground waters is a subject of great importance, since a lot of people use this kind of source for public supply. This paperwork manages with how gas stations can contaminate these waters and what are some remediation techniques, used nowadays to solve this problem. The contamination caused by the gas stations can have its origin in the underground storage tanks when they suffer corrosion and show leaking problems. It’s a topic of great relevance, because the hydrocarbons derivated from petroleum present in the fuels can stay for a long time in the environment. Besides that, an analyses of the risk of contamination by gas stations in the city of Rio Claro was made based on three parameters: density of the gas stations, depth of the underground water and hydraulic conductivity. To achieve such goal, maps were elaborated considering those parameters individually and considering the three of them together. Analyzing those maps, it was concluded see that the spots that represent the biggest risks of contamination in Rio Claro are located southeast and center-west.

Caracterização gfeológico-geotécnica aplicada a gestão de risco no gasoduto GASBOL, trecho Ipeúna/SP - Itirapina/SP

The pipelines are characterized by the great length and linearity, these enterprises are usually associated with the horizon of soil and decomposed rock and accidents in this system usually have high complexity. So this work proposes a study of geological and geotechnical characterization of approximately 40 km ² and a study of risk analysis along 18.3 km of gas pipeline GASBOL, in the municipalities of Ipeúna-SP and Itirapina-SP, in scale 1:25.000, besides correlation between studies. The method for geological and geotechnical characterization is based on physiographic integrated analysis technique, which is supported by literature research, observation and interpretation of satellite imagery (photointerpretation), correlation of products numerical model of ground, fieldwork. The method adopted for risk classification is based on preliminary analysis of hazards (APP) technique, which is identified the geological process, this feature is classified as the susceptibility of occurrence, and then classified as the possible consequence of the process, if this evolves. As a product of the research, we designed a map in 1:25,000 scale, containing a table of geological and geotechnical characteristics of the mapped drives, as well as sectorization risk in each section of the pipeline. Were mapped geological and geotechnical seven units in the study area, delimited in excerpts of which five are classified as high risk, totaling 1.1 km in length of 18.3 km total

Análise da variação da vazão e da concentração do metano presentes nos gases gerados no aterro sanitário de Rio Claro - SP

The study of the generation of landfill gas contributes to the understanding of the relationship between gas production and other parameters, such as time of disposal of waste and moisture (rainfall) and, thus, can subsidize the viability study for energy. This study aims to evaluate the interference of the time of disposal of waste and moisture (rainfall) in the production and composition of biogas generated at the landfill in Rio Claro - SP. As a result it was observed that for the landfill studied, the average percentage of methane in biogas ranged from 49.9% to 54.7%. It was found that moisture (rainfall) and the time of waste disposal are parameters which do not cause significant changes in methane concentration in biogas. However, when analyzed the flow of biogas, which had the maximum average value of 152.86m3/h and minimum average value of 15.47m3/h was observed great interference of moisture (rainfall) and the time of disposal of waste, because well of gas located in newer areas of the landfill showed higher values of flow rate than the areas where the landfill was the beginning of the arrangement. The same way, it was observed that in the dry season flow of biogas decreased in all drains gas analyzed

Caracterização do meio físico para definição de traçado e manutenção de multidutos na região do Vale do Paraíba

The present study characterizes the physical environment for its fragility and its capacity to support, through geological and geomorphological properties in the study area, concerning primarily with a sustainable environmental planning for the construction and maintenance of buried linear works. The study area is located on a portion of the Paraiba Valley, which is between the latitudes 22 °30' S and 23°00' S and longitudes 44°30' W and 45° 15' W, between cities of Aparecida (SP) and Queluz (SP). The methodology was based in the visual interpretation of TM/Landsat-7 images, using as a criterion the element textural image and its way of organizing space. To do so, it was set five levels of textural density, enabling thus to the partitioning of the area in areas counterparts (Z.H.s). As a result, it was identified 133 Z.H.s. By using the same criterion textural image the following physical properties were classified: Erosion Resistance, Permeability, Plasticity X Brittle, Tropia and Relief Asymmetry for each zone counterpart, and then grouped themselves as they hold all properties equal in Units Geoenvironmental (U.G.s). As a result it was identified 18 U.G.s. The work presents, as a final result, a thematic map with favorable or restrictable sectores to the design of buried linear works. Based on this map, it can be propose traces to buried linear works, analyzing their suitability to the physical environment and reducing the impacts caused to the environment.

Sistema de gestão ambiental: subsídios para a implantação em uma estação de tratamento de esgoto a partir da análise crítica de estudos ambientais prévios

The process of environmental impact assessment (EIA), in the extent of previous environmental studies, has as one of its functions to provide subsidies to the actions of environmental managment of enterprises. However, the proper estructuring of programs that allows to support this managment does not often occurs. This research sought as one of its objectives to evaluate in which extent the process of EIA can be a subsidie for the EMS, providing basic elements of this system. In addition, more specifically, the research had as one of its objetives the development of subsidies for the implantation of an Environmental Managment System (EMS), based on the model of ISO 14001 (2004), for a sewage treatment plant yet to be constructed in the city of President Venceslau / SP. In order to achieve theses objetives, a discussion was held based on the evaluation of environmental studies available in the library of Cetesb / SMA. Still, for the elaboration of subsidies for the EMS of the treatment plant, the research was focused on the structuring of environmental management program, based on the information contained in its Preliminary Environmental Report (PER). The research had as one of its products, the development of subsidies for the planning and control of the environmental aspects and impacts and for the environmental program of the enterprise, based on the use of environmental indicators. It was concluded, based on the results that, in general, the previous environmental studies analyzed showed little emphasis on the phase of development of structured environmental programs that offer guidelines to achieve the desired results for the environmental performance of the company.

Proposta para planejamento da arborização viária do bairro do Alvinópolis, município de Atibaia - SP

The urban arborization planning must consider technical criteria, to avoid future conflicts between trees and the urban space, and sociocultural criteria, to satisfy the local population necessities. Considering this principle, the present work proposes an arborization plan for a pilot area enclosing three of the principal streets from Alvinopolis District, county of Atibaia – SP. In order to tackle this objective, requests of tree removal were analyzed to get a panorama of how the subject takes place in the county. After that, promising sites for tree planting were selected in the enclosing area, and urban arborization of the three (3) main streets were retake, proposing necessary substitutions. Finally, 238 residents all over Alvinopolis County have been interviewed, with the objective of appraising their subject sense and focus on environmental education. Then three maps were made: the first one representing characteristics that influence in arborization, the second representing the present arborization and the nine (9) necessary substitutions, and the third representing the plan for the arborization of the pilot area. From the interviewed people, 79% shown themselves favorable to urban arborization, otherwise it does not discard the necessity to inform population about adequate species, county laws and adequate handling of trees.

Diagnóstico geoambiental e avaliação de risco à saúde humana em terminal de abastecimento no município de Sumaré - SP

The present work deals with the study on the evaluation of the human health risks caused by the leaching of hydrocarbon products from a gas station in Sumaré-SP. First, a geoenvironmental diagnosis had to be done, where information such as: history of the area, chemicals involved, geological characteristics, transport, chemical analysis, were used to make it. The geoenvironmental diagnosis was used in the software RBCA tier 2 which established the risks by all possible pathways. The results indicated that there are risks for groundwater ingestion for commercial (on site and off site) and residential receptors and 10 that there´s risk for inhalation of vapors in enclosed space for the commercial receptor on site. The evaluation also calculated the specific target levels that the area needs to show, in order not to harm human beings and the environment. That makes RBCA a great tool that can helps the remediation actions needed to be done so that the human being and the environment remain secure.
