1. Dissolved air Flotation , for clarifying water with low turbidity using aluminum sulphate and Moringa oleifera seeds as coagulants / Flotação por ar dissolvido na clarificação de águas com baixa turbidez utilizando sulfato de alumínio e sementes de Moringa oleifera como coagulantes
This work aims to investigate the process of Dissolved air Flotation (DAF) for clarifying water samples with low turbidity using aluminum sulphate and Moringa oleifera seeds as coagulants. The experimental procedure was carried out in a bench scale flotation unit. The influences on the pre-treatment conditions (coagulant dosage and flocculation time) and flo

2. Lamella design (high rate) and conventional flotation units applied to the post-treatment of the effluent from a system made up anaerobic reactor followed by aerobic reactor treating domestic sewage / Emprego da flotação lamelar de alta taxa e convencional como pós-tratamento do efluente de sistema constituído de reator anaeróbio seguido de reator aeróbio tratando esgoto sanitário
The aim of this research was the study of the lamella design (high rate) and conventional dissolved air flotation (DAF) process potentiality of application as the final part of a domestic sewage sequential treatment system made up anaerobic reactors (UASB) followed by aeration tank. The work, developed at the Jardim das Flores WWTP of Rio Claro city, was sep

3. Avaliação da influência da distribuição de tamanho de partículas e do binômio velocidade/tempo de detenção na zona de reação no desempenho da flotação com emprego de sonda ultra-sônica e de técnica de análise por imagem / Analysis of particles distribution size and the pair velocity/hydraulic residence time in the reaction zone performance of a flotation unit by using ultrasonic probe and image analysis
This work investigated the performance of a dissolved air flotation (DAF) pilot plant, used to treat drinking water containing 05 Tu and 50 Cu. The particles (micro-bubbles and flocs) and hydraulic characteristics were taken into account. The focus was given in the reaction zone as hypothesized by Realis mathematic model (REALI, 1991). An image analyses was
