1. Phosphorus dynamics in a highly polluted urban drainage channel-shallow reservoir system in the Brazilian semiarid
Abstract: This paper investigates phosphorus dynamics in a highly polluted system composed of a drainage channel followed by a shallow reservoir in the city of Fortaleza, Brazilian semiarid. During the dry season, significant non-point source loads of total phosphorus originated from residences unconnected to sewers were identified along the channel, resulti

3. SUSTENTABILIDADE NO USO DO FÓSFORO: UMA QUESTÃO DE SEGURANÇA HÍDRICA E ALIMENTAR
The phosphorus used as fertilizer in agriculture is extracted from phosphate rocks, which after extraction reacts with sulfuric acid, releasing phosphoric acid, a raw material for the fertilizer industry. Studies point to a possible depletion of world reserves of phosphate rock in the next 50-100 years. A phosphorus scarcity is closely linked to global food

4. Avaliação da toxicidade de efluente sanitário tratado e condicionado para aplicação na agricultura, utilizando Allium cepa, Daphnia similis e Vibrio fischeri, como organismos-teste / Toxicity assessment of treated sanitary effluent for application in agriculture, using Allium cepa, Vibrio fischeri and Daphnia similis as test organisms
O uso de efluente tratado na agricultura irrigada constitui uma alternativa adequada para a preservação de mananciais, além de ser uma importante fonte de nutrientes. No entanto, os riscos de toxicidade devem ser avaliados. Testes ecotoxicológicos apresentam-se como uma ferramenta apropriada, devido à sensibilidade dos organismos e sua ampla aceitação

6. Avaliação da qualidade da água de chuva e de um sistema filtro-vala-trincheira de infiltração no tratamento do escoamento superficial direto predial em escala real em São Carlos SP / Evaluation of rainfall water quality and a filter-swaleinfiltration trenches system in the treatment of the building direct runoff in real scale in são carlos sp
Several studies cite the pollution of stormwater as equivalent and sometimes even superior to those found in the sewers. According to this premise and thinking about environmental issues, especially in the contamination of groundwater and the spread of waterborne diseases, the quality of rainwater has become an important focus of study. This work concerns th

8. Controlled disposal of effluent domestic sewage in the ground a study of the reduction of fecal coliforms / Disposição no solo de efluentes de esgoto tratado visando a redução de coliformes termotolerantes
The indiscriminate launching in the water courses of sewers domestic without treatment, or exactly treat, but without appropriate disinfection, contributes with significant amount of organisms of the called "coliform group", between which specific agents of illnesses of water propagation can be present. The application of the effluent in the ground, instead

9. Evaluation of the gradient precision of the horizontal directional drilling technique for the installation of gravity sewers / Avaliação da precisão da declividade da técnica de perfuração direcional horizontal para instalações de redes de esgoto
The present work is focused on the horizontal directional drilling (HDD) method to install gravity sewers. The results of different techniques are described intending to meet the demands of gradient. Therefore, 4 experimental pilot bores were drilled simulating a section of those structures extending 30 m with HDPE pipelines of 125 mm external diameter. Thos

12. Effects of the accepting water treatment plants (WTP) residuals at wastewater treatment plant (WWTP) using SBR activated-sludge process with extended aeration in the city of Juquitiba, SP. / Efeitos do recebimento do lodo da estação de tratamento de água pelo sistema de tratamento de esgoto por lodo ativado em bateladas e aeração prolongada do município de Juquitiba - SP.
There are different technical engineering solutions for the treatment and final disposal of water treatment plants (WTPs) residuals. Discharge of WTP residual to a wastewater treatment plant (WWTP) is a technical solution in evidence. Therefore, the purpose of this study was to evaluate the capacity of the WWTP using sequencing batch reactor (SBR) activated-
