1. EFFECT OF ALUMINUM SULFATE AND CATIONIC POLYMER ADDITION IN THE MIXED LIQUOR OF A SUBMERGED MEMBRANE BIOREACTOR (SMBR): SLUDGE CHARACTERISTICS AND ORTHOPHOSPHATE REMOVAL IN BATCH EXPERIMENTS
Abstract Submerged Membranes Bioreactors (SMBR) are an established technology for wastewater treatment for water recovery and reuse. However, its routine application is still compromised by the high energy consumption to overcome the fouling effect. This study evaluated the effect of aluminum sulfate and cationic polymer in the orthophosphate removal and slu

2. INFLUENCE OF THE APPLIED ORGANIC LOAD (OLR) ON TEXTILE WASTEWATER TREATMENT USING SUBMERGED ANAEROBIC MEMBRANE BIOREACTORS (SAMBR) IN THE PRESENCE OF REDOX MEDIATOR AND POWDERED ACTIVATED CARBON (PAC)
Abstract This paper evaluated the treatment of textile wastewater in submerged anaerobic membrane bioreactors (SAMBR) operated on a bench scale. Particularly, the influence of operational conditions, such as the applied organic rate (OLR) and the dilution factor (for toxicity attenuation) of the textile wastewater, was evaluated on color and organic matter r

3. REUSE OF DAIRY WASTEWATER TREATED BY MEMBRANE BIOREACTOR AND NANOFILTRATION: TECHNICAL AND ECONOMIC FEASIBILITY
Abstract This study evaluated the technical and economic feasibility of membrane bioreactors (MBR) followed by nanofiltration (NF) for dairy wastewater treatment in order to reuse the treated effluent. It was observed that the MBR efficiently removed the organic matter and color of the feed effluent; however, due to the high concentration of dissolved solids

4. Tratamento com lodo aeróbio granular de efluente de fábrica de papel / Aerobic granular sludge treatment of paper mill effluents
The activated sludge process is widely used for the treatment of industrial effluents, achieving high rates of organic matter removal. Nevertheless, the separation of biological sludge in secondary clarifiers can be a serious problem of this process due to the poor floc formation, causing solids losses and, consequently, deterioration of treated effluent qua

5. Caracterização de comunidades bacterianas mesófilas e termófilas em biorreatores a membrana durante o tratamento de efluentes de fábrica de papel reciclado / Characterization of mesophilic and thermophilic bacterial communities in membrane bioreactors during treatment of recycled paper mill effluents
Paper mils consume large quantities of water and thus generate high volume of effluents. Biological treatment of paper mils industrial effluent is widely used for this purpose. The new technology of membrane bioreactors under thermophilic conditions is still underused due to the lack of sufficient technical and scientific knowledge. In spite of their importa

6. Study of breathing activity of wild and transfected line of insect cells through cultivations in bioreactors. / Estudo da atividade respiratória de linhagens selvagens e transfectadas de células de insetos através de cultivos em biorreatores.
Specific respiration rate (QO2) is a key parameter to understand cell metabolism and physiological state, providing useful information for process supervision and control. In this work, we cultivated different insect cells in a very controlled environment, being able to measure QO2 and critical oxygen concentration (Ccrit). Wild Spodoptera frugiperda (Sf9) a

7. Tratamento de lixiviado através de filtro anaeróbio associado a membrana de microfiltração
Nowadays, the use of membrane bioreactors (MBRs) has been researched in many places of the world to treat different kinds of wastewater. The use of MBRs has advantages over other processes when the main focus is on the reuse of wastewater, small areas for wastewater treatment plant or restricted laws conditions. Commonly, the MBRs have been designed with sus

8. Examination of Bacterial Characteristics of Anaerobic Membrane Bioreactors in Three Pilot-Scale Plants for Treating Low-Strength Wastewater by Application of the Colony-Forming-Curve Analysis Method
Characteristic sludge ecosystems arising in anaerobic membrane bioreactors of three pilot-scale plants treating low-strength (less than 1 g of biological oxygen demand per liter) sewage or soybean-processing wastewater were examined by analysis of the colony-forming-curves (CFC) obtained by counting colonies at suitable intervals. The wastewaters, containing

9. Ethanol Production by Saccharomyces cerevisiae Immobilized in Hollow-Fiber Membrane Bioreactors
Saccharomyces cerevisiae ATCC 4126 was grown within the macroporous matrix of asymmetric-walled polysulfone hollow-fiber membranes and on the exterior surfaces of isotropic-walled polypropylene hollow-fiber membranes. Nutrients were supplied and products were removed by single-pass perfusion of the fiber lumens. Growth of yeast cells within the macrovoids of
