a membrane bioreactor (mbr) system based on a dead-end immersed hollow fiber membrane and filamentous fungus aspergillus oryzae were used for treatment of baker’s yeast wastewater. the fungus was adapted to the wastewater in the bioreactor for two weeks before starting the continuous process. average organic loading rate of 4.2 kg cod/m3.d was entered the bioreactor. mbr system was able to redu...

the present work studied the application of membrane bioreactor (mbr) for tapioca wastewater processing that contained chemical oxygen demand (cod) ranging from 4000-9000 mg/l. a preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with mlss concentration ranging from 4,500 to 10,500 mg/l. it was clear that fouling was observed during the ...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

background: the purpose of this study was to investigate the efficiency of flat sheet membrane bioreactor (fs-mbr) in bod 5 and cod removal of isfahan south municipal wastewater treatment plant. methods: in this study a submerged fs-mbr, with 140 liters volume was fed using microfiltration membrane (mf) during 109 days and hydraulic retention time of 20 hours. findings: the mbr application in m...

Zirconia ultrafiltration membranes are widely developed and used for past several years. But the conventional sol-gel methods of zirconia membrane preparation involve many steps. In the present study an attempt was made to develop defect free zirconia ultrafiltration (UF) membrane in single step coating of zirconia nanopowder suspension by slip casting method over multichannel ceramic support. ...

background: considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. the purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane bioreac...

textile wastewaters due to the toxic effects of dyestuffs and other organic compounds and their stability toward light and oxidizing agents have led to an environmental problem. several treatment methods for dye removal have been investigated. membrane process is one of the simplest and most effective methods for dye removal from industrial wastewaters. electrospun nanofibrous membranes have hi...

This study demonstrated the feasibility of implementing of MBR in pharmaceutical wastewater independently, and concluded different applications of MBR in industries. Membrane bioreactor (MBR) technology was a new wastewater treatment technology with a combination of membrane separation technology and biological treatment technology, which had unique advantages on pharmaceutical wastewater treat...

Background: Application of membrane technology to wastewater treatment has expanded over the last decades due to increasingly stringent legislation, greater opportunities for water reuse/recycling processes and continuing advancement in membrane technology. Objectives: In the present study, a bench-scale submerged microfiltration membrane bioreactor (MBR) was used to assess the treatment of tex...
