The use of rainwater for non-potable purposes generates a reduction in the consumption of treated water, however, this reduction is not observed in the generation of wastewater, as this is independent of the water source. In Brazil, the pricing on the services of collection and treatment of sewage, in general, is based on the coefficient of return of the sewage disposal system, which has a relation sewer / water proportional to the consumption of treated water measured at the consumer unit. The use of rainwater originating from utilization systems infer on the coefficient, underestimating the volume of wastewater generated. Therefore, this study presents a methodology for setting the coefficient of return. Different roof areas, reservoir volumes and rates of water consumption situations were simulated. The behavior of adjustment of the coefficient of return were also analyzed for the average area per capita roof (m² / inhabitant) of Rio Claro - SP. As a result, it can be seen that the adjustment of the coefficient of return is directly proportional to the increase of the roof areas and the volumes of reservoirs, and inversely proportional to the total water demand. The corrected coefficient of return showed the minimum value of 0.83 and a maximum value of 1.45, this variation corresponds to the maximum ratio between the demands of total water and rainwater, since the exploitation of rain water should be used only for non-potable uses, according to NBR 15527 / 07. To the municipality of Rio Claro - SP was noted an adjustment of the coefficient of return ranging from 0.99 to 6.61

The anaerobic treatment of sewage is widely employed in Brazil and it is an appreciated way for the treatment of effluents, helping to reduce the environmental impact in rivers. The methane gas obtained from the process can be applied to improve the energetic efficiency of the system, reducing the amount of waste and the cost of the treatment process. This work presents the net energy balance of anaerobic reactors applied to the treatment of sewage. The analysis was performed considering full-scale and laboratory-scale treatment systems. In laboratory scale, the results from three kinds of systems were compared regarding the biological treatment of greywater. Two of them (UASB7 and UASB12) were anaerobic and the other one was a combined anaerobic-aerobic system (UASB7/SBR6). Greywater methanization (compared to theoretical maximum) was calculated considering 100% removal (g BOD/day), the literature percentage removal and the anionic surfactant presence in the effluentt. For each of these three cases, the efficiencies were, respectively, 16.9%, 43.6% and 51.3% in UASB7 reactor, 25.6%, 50.3% and 59.2% in UASB12 reactor and 30.6%, 61.2% and 71.9% in UASB7/SBR6 reactor. The energetic potential was found to be 4.66x10-4, 7.77x10-4 and 5.12x10-4 kWh/L for the UASB7, UASB12 and UASB7/SBR6 reactors, respectively. The pumping system, the aeration (in the anaerobic-aerobic system) and the temperature controlled heating system were considered to calculate the energetic consumption. However, the third one was not employed since tropical regions like Brazil do not need heating systems and also because of its high energetic consumption. The calculated net energy balance in the reactors was negative in the case of greywater, respectively -0.16, -0.28 and -0.18 kWh/L for the reactors UASB7, UASB12 and UASB7/SRB6. In full scale (ETE Jardim das Flores - Rio Claro, SP), the average energy... (Complete abstract click electronic access below)

Novos hábitos alimentares da população e as mudanças nos sistemas de produção e distribuição dos alimentos podem estar fortemente relacionados aos casos de doenças transmitidas pelo consumo de alimentos contaminados por microorganismos. Isso faz com que a preocupação com a qualidade microbiológica dos alimentos aumente mundialmente. Dentre os principais patógenos, destaca-se a Salmonella sp, que pertence à microbiota gatrentestinal de animais silvestres e de animais domésticos criados para o consumo humano (aves, bovinos e suínos). Este fato torna o problema de grande relevância para as autoridades de saúde pública, pois esses microrganismos podem estar associados às infecções ou surtos provocados pela ingestão de alimentos contaminados. Foram coletadas 35 amostras de lingüiças e 25 cortes de frango, nos principais supermercados do município de Botucatu-SP e avaliados quanto à qualidade higiênico-sanitária através da determinação do número mais provável de coliformes termotolerantes (CT), além da presença de Salmonella sp. Os resultados obtidos mostram que 31% das lingüiças e 84% das amostras de frango estavam fora dos padrões higiênico-sanitários estabelecido pela ANVISA (RDC n° 12), que determina uma quantidade máxima de 5x103 CT/g em lingüiça e 104 /g em carne de aves. Em relação à Salmonella sp, estabeleceu-se a ausência dessa bactéria em 25g de lingüiça e não determina nenhum parâmetro para o frango. Entre as 25 amostras de frango analisadas, duas (8%) foram positivas pela metodologia tradicional. Esse... (Resumo completo, clicar acesso eletrônico abaixo)

This research was mainly focused on public policy analysis of solid waste, and the National Policy and State Solid Waste, as well as determining the performance of the Blue Green Municipality strategic project in relation to the management of municipal solid waste in Regente Feijó, São Paulo. The objective of this research was to analysis of the consequences of the deployment project of selective collection and integration of recyclable material collectors in an association of collectors, called the Association of Recyclable Material Collectors Rock, held in the city from the year 2008, with effective implementation in 2010. We analyzed the actions of the municipal government since the implementation of selective collection, to the development of the Association. The methodology used was literature concerning the issue; routine field surveys to monitor the activities in the landfill and association of collectors, collecting data from questionnaires appropriate to the research topic. We sought to examine old and new forms of urban solid waste management, the evolution of the historical process of this issue in the city and its social and environmental impacts, and the collectors the main social actors in this process. The complexity that addresses this issue was dealt with in this dynamic study, analyzing all parts involved

Geological-geotechnical problems affecting escarps as well as embankment and fill slopes of roads and motorways may generate different types of unsteadiness, which are mainly arisen from the deficient knowledge about the physical environment. This results in unsuitable engineering projects and inadequate executions, which can be worsened by an occasional inappropriate maintenance of the construction. A geologically-geotechnically characterization of escarps and slopes is crucial in order to prevent these problems. This work deals with a geological-geotechnical study of 1:10.000 scale mapping in a stretch of a local road (CHQ-40) at the Serra de Itaqueri, Charqueada town, State of São Paulo. The stretch is known by several physical problems as erosion and mass movement. The methods of study were based on an integrative analysis of the diverse elements of the physical environment by using aerial photographs - to obtain the physiographic compartmentalization of terrain units - as well as field work - to accomplish the evaluation of the units by employing sketch lists. To achieve this, we selected several techniques in order to identify and classify different types of existing problems as erosion, landslide in embankments and fill slopes, rockfall, block rolling, among others. We also included the analysis of soil horizon, thickness and composition. The geological-geotechnical mapping resulted in six units: 1- Sandstones in cuesta’s backhill; 2 – Basalts in cuesta’s front; 3- Sandstones in cuesta’s front; 4 – Talus and colluvial deposits at cuesta’s foothill; 5- Sandstones of the Piramboia Formation in hillside; and 6 – Colluvial soil in the hill top. A characterization of the geological-geotechnical units is detailed, coupled to the cartographic material. Other cartographic products elaborated for this study included 1:10.000 maps of hypsometry, slope and curvature
