25. Avaliação da eficiência da remoção de matéria orgânica e microbiológica de três sistemas de lagoas de estabilização em série na Grande Natal-RN: Beira Rio, Jardim Lola I e Jardim Lola II
Waste stabilization ponds are the main technology in use for domestic sewage treatment in Rio Grande do Norte State (RN), northeast Brazil. The are around 80 systems, constructed mainly by municipal city halls, being series comprised by a primary facultative pond followed by two maturation ponds the most used configuration. Due to problems related with the p

26. Influência do deságue do sistema de lagoas de estabilização na quantidade de nutrientes no Igarapé Grande, Boa Vista, Roraima
The Igrarapé (small streams) Grande, in Boa Vista, Roraima, is the receiving body of the wasterwater generated starting from the waste stabilization ponds, system of treatment of the sanitary sewers of part of the city. By the hypothesis that the spilling of those wasterwater in referred him body of water contributes so that the same presents physiochemical

27. Avaliation of the sanitary, agronomics and final product quality aspects in watermelons irrigated with treated sewage / Avaliação dos Aspectos Sanitários, Agronomicos e de Qualidade em Melancias Irrigadas com Esgoto Tratado
The reuse of treated sewage on watermelon irrigation, variety Crimson Sweet, was investigated not only considering the sanitary aspects but also the productivity and final product quality. The experiment was conducted in the Research Centre on Wastewater Treatment and Reuse, owned by the Company of Water and Wastewater of Ceará, in Aquiraz-CE. The experimen

28. Productivity of the castor seed,irrigated with domestic wastewater treated in stabilization pond. / Produtividade da Mamona, Irrigada com Esgoto Doméstico Tratado em Lagoas de Estabilização
The castor tree (Ricinus communis Linn) represents a huge potential to the economy of the semi-arid region located in the Northeast of Brazil, as an alternative crop for biodiesel production. Effluents reuse in agriculture is a water alternative for regions with water shortage, such as Northeast of Brazil. In this research, the castor seed was irrigated by u

29. Characterization of shrimp ponds and effluents sedimentation pond in Rio Grande do Norte: subsidies to the protection of the ecosystems in this study / Caracterização dos meios de cultivo de viveiros de carcinicultura e da lagoa de disposição dos efluentes no Rio Grande do Norte: subsídios para proteção dos ecossistemas deste estudo
O cultivo de camarões é uma importante atividade econômica em zonas costeiras de muitos países. No Brasil, a carcinicultura teve início no Rio Grande do Norte em 1973 e, atualmente, consolida-se como principal produto da pauta de exportação desse estado, sucesso devido principalmente ao seu clima semi-árido, à vasta costa litorânea com extensas ár

30. Remoción de formas parasitarias intestinales en una laguna facultativa de estabilización en Lima, Perú
The effectiveness of a waste stabilization pond, to remove intestinal helminth eggs and protozoan cysts was studied in San Martin de Porres, Lima, Peru. From September to October 2000 four collections of samples were performed from raw domestic wastewater and from contends of primary, secondary and tertiary ponds. A comparative study of performance of the co

31. Remoção de algas via alimentação pelo microcrustáceo dendrocephalus brasiliensis (crustácea : anostraca)
O presente trabalho pesquisou a sobrevivência do crustáceo Dendrocephalus brasiliensis e as taxas de remoção de algas via alimentação, de efluente de lagoas de estabilização de uma indústria de esmagamento de soja. Os índices de sobrevivência foram testados com 20 náuplios.L-1 de efluente em temperatura controlada a 27oC e o resultado médio foi

32. Sunlight Inactivation of Fecal Indicator Bacteria and Bacteriophages from Waste Stabilization Pond Effluent in Fresh and Saline Waters
Sunlight inactivation in fresh (river) water of fecal coliforms, enterococci, Escherichia coli, somatic coliphages, and F-RNA phages from waste stabilization pond (WSP) effluent was compared. Ten experiments were conducted outdoors in 300-liter chambers, held at 14°C (mean river water temperature). Sunlight inactivation (kS) rates, as a function of cumulati

33. Influence of pH, Oxygen, and Humic Substances on Ability of Sunlight To Damage Fecal Coliforms in Waste Stabilization Pond Water
Simple beaker experiments established that light damages fecal coliforms in waste stabilization ponds by an oxygen-mediated exogenous photosensitization. Wavelengths of up to 700 nm were able to damage bacteria. The ability of wavelengths of >425 nm to damage fecal coliforms was dependent on the presence of dissolved sensitizers. The sensitizers were ubiquit

34. Sunlight Inactivation of Fecal Bacteriophages and Bacteria in Sewage-Polluted Seawater
Sunlight inactivation rates of somatic coliphages, F-specific RNA bacteriophages (F-RNA phages), and fecal coliforms were compared in seven summer and three winter survival experiments. Experiments were conducted outdoors, using 300-liter 2% (vol/vol) sewage-seawater mixtures held in open-top chambers. Dark inactivation rates (kDs), measured from exponential
