Variação espacial e temporal da qualidade da água de três córregos tributários do Rio Bauru: respostas ao processo de recuperação de nascentes

Este trabalho objetivou analisar a qualidade da água de três córregos tributários do rio Bauru, levando em conta a poluição causada por produtos orgânicos e industriais que vinham sendo descartados nos mesmos e as eventuais melhorias conseqüentes das medidas paliativas assumidas pelo DAE-Bauru, mediante a instalação de interceptores-coletores de águas residuárias ao longo Daqueles corpos de água, até que a Estação de Tratamento de Esgotos do município seja construída e se dê início ao seu funcionamento. O monitoramento destes corpos de água durante o período de estiagem e de cheias proposto nesta pesquisa, incluiu investigações sobre as variáveis químicas e físicas de amostras das águas, obtidas mensalmente em 7 pontos de coleta, localizados a montante e a jusante dos pontos de instalação dos emissários, ao longo dos córregos. As amostras de água foram posteriormente analisadas para fossem obtidas informações sobre a eficácia da instalação dos interceptores com relação ao processo de recuperação da saúde dos corpos aquáticos em questão. Os resultados obtidos mostraram que, de um modo geral, as águas de todos os sistemas estudados ainda sofrem impactos, até porque ainda há aquelas que recebem o esgoto descartado “in natura”. No entanto, como ja era esperado, nos pontos de coleta localizados em segmentos dos córregos nos quais os emissários já foram instalados, o impacto ambiental é menor. Mediante a comparação dos resultados obtidos das análises das características físicas e químicas das águas dos sistemas estudados realizadas durante esta investigação com aqueles obtidos nos mesmos corpos de água, em 2007, pudemos observar melhorias da água em alguns dos pontos de coleta

Sistema automatizado para o aproveitamento de água cinza e azul, com controle de PH utilizando lógica fuzzy

Every day, water scarcity becomes a more serious problem and, directly affects global society. Studies are directed in order to raise awareness of the rational use of this natural asset that is essential to our survival. Only 0.007% of the water available in the world have easy access and can be consumed by humans, it can be found in rivers, lakes, etc... To better take advantage of the water used in homes and small businesses, reuse projects are often implemented, resulting in savings for customers of water utilities. The reuse projects involve several areas of engineering, like Environmental, Chemical, Electrical and Computer Engineering. The last two are responsible for the control of the process, which aims to make gray water (soapy water), and clear blue water (rain water), ideal for consumption, or for use in watering gardens, flushing, among others applications. Water has several features that should be taken into consideration when it comes to working its reuse. Some of the features are, turbidity, temperature, electrical conductivity and, pH. In this document there is a proposal to control the pH (potential Hydrogen) through a microcontroller, using the fuzzy logic as strategy of control. The controller was developed in the fuzzy toolbox of Matlab®

Sewage disposal and wildlife health in Antarctica

Sewage and its microbiology, treatment and disposal are important to the topic of Antarctic wildlife health because disposal of untreated sewage effluent into the Antarctic marine environment is both allowed and commonplace. Human sewage contains enteric bacteria as normal flora, and has the potential to contain parasites, bacteria and viruses which may prove pathogenic to Antarctic wildlife. Treatment can reduce levels of micro-organisms in sewage effluent, but is not a requirement of the Environmental Protocol to the Antarctic Treaty (the Madrid Protocol). In contrast, the deliberate release of non-native organisms for any other reason is prohibited. Hence, disposal of sewage effluent to the marine environment is the only activity routinely undertaken in Antarctica knowing that it will likely result in the release of large numbers of potentially non-native species. When the Madrid Protocol was negotiated, the decision to allow release of untreated sewage effluent was considered the only pragmatic option, as a prohibition would have been costly, and may not have been achievable by many Antarctic operators. In addition, at that time the potential for transmission of pathogens to wildlife from sewage was not emphasised as a significant potential risk. Since then, the transmission of disease-causing agents between species is more widely recognised and it is now timely to consider the risks of continued discharge of sewage effluent in Antarctica and whether there are practical alternatives.
