3. Tratamento de Ãguas residuÃrias da indÃstria de laticÃnios pelos processos combinados coagulaÃÃo/floculaÃÃo/adsorÃÃo/ultrafiltraÃÃo utilizando semente de Moringa oleÃfera como coagulante / Wastewater treatment of dairy industry by combined process coagulation/flocculation/adsorption/ultrafiltration using Moringa oleÃfera seed as coagulant
No Brasil, as indÃstrias de laticÃnios na sua maioria sÃo de pequeno e mÃdio porte e utilizam tÃcnicas de tratamento convencionais somadas ao uso de coagulantes inorgÃnicos. Por isso, este setor precisa de atenÃÃo especial no que se refere a tÃcnicas avanÃadas para o tratamento de suas Ãguas residuÃrias, com objetivo de atender as novas regulamen

4. Tratamento de água para consumo humano de reservatório eutrofizado através de pré e interoxidação, adsorção em carvão ativado e dupla filtração / Drinking water treatment of eutrophic reservoir by pre and interoxidation, activated carbon adsorption and double filtration
Disordered basins occupation provoked acceleration of eutrophication, which besides purely aesthetic and landscaping problems, results in occurrence of high phytoplankton densities with potentially toxic cyanobacteria dominance. Alongside physical aging and consequent deterioration of installations, usual treatment technologies do not provide adequate condit

5. Avaliação de catalisadores a base de carbeto e nitreto de molibdênio na obtenção de lactitol via hidrogenação da lactose / Avaliação de catalisadores a base de carbeto e nitreto de molibdênio na obtenção de lactitol via hidrogenação da lactose
Seeking a greater appreciation of cheese whey was developed to process the hydrogenation of lactose for the production of lactitol, a polyol with high added value, using the catalyst Ni / activated carbon (15% and 20% nickel), the nitride Mo2N, the bimetallic carbide Ni-Mo/ activated carbon and carbide Mo2C. After synthesis, the prepared catalysts were analy

6. Adsorption of human immunoglobulin G to poly ( β-hydroxybutyrate) (PHB), poly (L- lactic Acid) (PLLA) and PHB/PLLA blends
Biodegradable polymeric materials can be used as temporary implants and may be able to carry out specific functions for a pre-determined period prior to their degradation in vivo. In order to be used they must present characteristics of biocompatibility. When a material comes into contact with blood, the instantaneous adsorption of protein occurs on its surf

7. Removal of microcystins in water from eutrophic reservoir involving technical of clarification, pre-oxidation with potassium permanangate, adsorption with powdered activated carbon and post-chlorination / Remoção de microcistina em águas provenientes de reservatório eutrofizado associando técnicas de clarificação, pré-oxidação com permanganato de potássio, adsorção em carvão ativado e pós-cloração
The present work had as objective to evaluate the removal of three different concentrations of extracellular microcystins in different combinations of water treatment for supplying, in bench scale, that had as basic sequence the clarification associated or not with the processes of pre-oxidation with KMNO IND.4, adsorption on PAC and post-chlorination. The r

8. Remoção de corantes em efluentes têxteis utilizando espumas de poliuretano e resíduos de sementes de Mabea fistulifera Mart. / Dye removal in textile effluents using polyurethane foams and residues of Mabea fistulifera Mart.
The absorption is successfully used in removing the organic contaminants found in textile effluent. This work proposes the use of alternative absorbents to remove the direct dyes (Direct Red 80) and reactive (Reactive Blue 21) in aqueous solutions and in effluent samples. Two absorbents were tested: the synthetic polyurethane foams (EPUs) and the seed residu

9. Purification and biochemical and functional characterization of fibrinogen from plasma of Bothrops jararaca (Wied, 1824) (Ophidia: Viperidae, Crotalinae) / Purificação e caracterização bioquímica e funcional do fibrinogênio do plasma da serpente Bothrops jararaca (Wied, 1824) (Ophidia: Viperidae, Crotalinae)
Fibrinogen is a plasma glycoprotein that is composed of two sets of three nonidentical polypeptide chains (Aα Bβ and ϒ ) which are covalently linked by disulfide bonds. Thrombin cleaves fibrinogen to form fibrin and, consequently, the fibrin clot. This work describes the purification and characterization of fibrinogen from Bothrops jararaca (B

10. Use of Powdered Activated Carbon to Remove the Herbicides Diuron and Hexazinone from Surface Water / Uso de carvão ativado pulverizado para remoção dos herbicidas diuron e hexazinona de água superficial
The Pardo River, the main source of surface water in the northeastern region of the state of São Paulo, flows through the worlds largest sugar and alcohol production pole, which causes it to become polluted with pesticides such as diuron and hexazinone that are used in the cultivation of sugarcane. In this study, the waters of the Pardo River were monitored

11. 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

12. Pré-cloração associada à adsorção em carvão ativado em pó e flotação por ar dissolvido na remoção de microcistina presente em três diferentes concentrações em águas provenientes de reservatório eutrofizado / Prechlorination associated to adsorption with powdered activated carbon and dissolved air flotation in the removal of three concentrations of microcystin present in eutroficated reservoir water
The disordered growth of cities, the use of planting areas near the water sources and the launch of domestic and industrial wastewater without treatment are the main sources of water bodiespollution. Such pollution contributes to increase the nutrient loading in the water bodies. In association with climatic factors, this enrichment of nutrient provides suit
