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. KINETICS ASPECTS OF CHROMIUM (III) REMOVAL BY PRECIPITATE FLOTATION / ASPECTOS CINÉTICOS DA REMOÇÃO DE CROMO (III) POR FLOTAÇÃO DE PRECIPITADOS
Heavy metals contained in industrial effluents are sources of great potential environmental degradation, since their presence produce physicochemical alterations harming in the quality of the water. These alterations have a direct impact in the mortality of the flora and fauna affecting indirectly the human health. This dissertation refers to the study of th

3. Optimizing dissolved air flotation design system
Dissolved Air (Pressure) Flotation-DAF, is a well-established separation process that employs micro-bubbles as a carrier phase. This work shows results concerning bubble generation at low working pressures in modified DAF-units to improve the collection of fragile coagula by bubbles. DAF of Fe (OH)3 (as model) was studied as a function of saturation pressure
