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

3. Application of submerged membrane bioreactor technology for the treatment of high strength dairy wastewater
Abstract In this study, an aerobic submerged membrane bioreactor (sMBR) was used for the treatment of dairy wastewater at 15 h of hydraulic retention time (HRT) and 40 d of sludge retention time (SRT) with constant permeate flux (9.5 L.m-3.d-1(LMH)). The COD, ammonia-nitrogen (NH3-N) and orthophosphate (PO4-P) removal efficiencies were 98.2%, 95.4% and 88.9%

4. Wastewater treatment in a pilot-scale submerged membrane bioreactor: study of hydrodynamics under constant operating pressure
Abstract A pilot-scale Submerged Membrane Bioreactor provided with PEI hollow fiber membranes was operated under constant pressure mode in order to evaluate the effects of hydrodynamic conditions on the process performance, such as air flow rate, module packing density and aeration configuration. For the three different air flow rates studied (2, 5 and 8 L/m

5. 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

6. Comparison between a conventional membrane bioreactor (C-MBR) and a biofilm membrane bioreactor (BF-MBR) for domestic wastewater treatment
In this paper, the influence of biofilm carriers in a MBR on the performance of organic matter and nitrogen removal and the influence on membrane fouling were evaluated. The configurations studied included a Conventional Membrane Bioreactor (C-MBR) and a Biofilm Membrane Bioreactor (BF-MBR) operated in parallel, both fed with domestic wastewater. Regarding o

7. Treatment of dairy wastewater with a membrane bioreactor
Among the food industries, the dairy industry is considered to be the most polluting one because of the large volume of wastewater generated and its high organic load. In this study, an aerobic membrane bioreactor (MBR) was used for the treatment of wastewater from a large dairy industry and two hydraulic retention times (HRT), 6 and 8 hours, were evaluated.

11. Kinetic study of Drosophila melanogaster cells transfected to produce the rabies vírus glycoprotein in bioreactor / Estudo cinético de células de Drosophila melanogaster transfectadas para a produção da glicoproteína da raiva em biorreator
The interest in using insect cells to produce complex proteins is due to its ease of cultivation and its glycosylation pattern equivalent to that of mammalian cells systems. The objective of this work was to identify the limiting or inhibiting factors for the production of a rabies virus glycoprotein (RVGP), expressed in the cytoplasmatic membrane of a trans

12. 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
