Submerged Anaerobic Membrane Bioreactors Hydrodynamics
In recent years,anaerobic membrane bioreactors (AnMBR),particularly submerged ones,have been evolving as a promising technology for wastewater treatment because,in addition to its many operational advantages,theres also the generation of biogas,which can be used as a renewable energy resource.However,the behavior prediction in these systems is especially complex,and it still lacks models to represent membrane fouling in AnMBRs.The aim of this study was to obtain and analyze experimental data on permeate flux and the correspondent total resistance in the postfiltration of the effluent of a UASB (Upflow Anaerobic Sludge Blanket) reactor through submerged polymeric hollow-fiber ultrafiltration membranes.The experimental tests provided data regarding total resistance of the membrane versus permeate flux in five different conditions of total suspended solids concentration and transmembrane pressure.From the economic and energetic point of view,the results show that the lowest suction pressure (140 mbar) can reach permeate volumes very close to the highest pressure tested with lower energy demand,in the same time.The results evidenced the importance of this type of research and the need for expansion,since the definition of adequate parameters and models would help to develop and increase the application of AnMBR systems and its well-known advantages.
