Textile manufacturing consumes a considerable amount of water in its manufacturing processes. The water is primarily utilized in the dyeing and finishing operations of the textile establishments. Considering both the volume generated and the effluent composition, the textile industry wastewater is rated as the most polluting among all industrial sectors. In this study a combined anaerobic-aerob...

In this study, a lab-scale fixed-film bio-media process was developed and operated to evaluate nitrogen removal from domestic sewage treatment plants. For removal, the applied in series with anaerobic, anoxic, aerobic units three separate reactors that were continuously at same loading rates hydraulic retention time. A biofilm separation bioreactor for on-site wastewater employed synthetic fibe...

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...

This study aimed to investigate the performance of microbial fuel cell (MFC) for simultaneous bioremediation of slaughterhouse wastewater and sustainable power generation. For the first time, an integrated system of tubular type microbial fuel cell (MFC) was used in this study. The MFC consisted of three concentric Plexiglas tubes; the inner tube was the anaerobic anodic compartment, the mid tu...

Microbial fuel cells (MFCs) are a promising technology for energy-efficient domestic wastewater treatment, but the effluent quality has typically not been sufficient for discharge without further treatment. A two-stage laboratory-scale combined treatment process, consisting of microbial fuel cells and an anaerobic fluidized bed membrane bioreactor (MFC-AFMBR), was examined here to produce high ...

(Received: June 5, 2011; Accepted: July 29, 2011) Abstract: Effect of increase in phenol concentration on performance of anaerobic baffled reactor in terms of chemical oxygen demand (COD), phenol and COD removal efficiency and biogas productions was investigated. Furthermore, stability of the reactor with respect to the chemical shock load was monitored. The anaerobic baffled reactor was contin...

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...

Hydrogen gas (∼60% H2) was produced in a continuous flow bioreactor inoculated with heat-treated soil, and fed synthetic wastewater containing glucose (9.5 g l). The pH in the bioreactor was maintained at 5.5 to inhibit consumption of H2 by methanogens. The objective of this study was to characterize bacterial communities in the reactor operated under two different hydraulic retention times (HR...

The objective of this paper is to critically review the significance of MBR technology for wastewater treatment derived Biodiesel plant with Alkali-Catalyzed Trans-esterification process. The whole study was carried out into two stages. In the first stage, pretreatment was studied with H2SO4 at the different pH range of 2.4 to 9 along with the removal efficiencies of BOD, COD and Oil & Greases....

Sustainable municipal wastewater recovery scenarios highlight benefits of anaerobic membrane bioreactors (AnMBRs). However, influences of continuous seeding by influent wastewater and temperature on attached-growth AnMBRs are not well understood. In this study, four bench-scale AnMBR operated at 10 and 25°C were fed synthetic (SPE) and then real (PE) primary effluent municipal wastewater. Illum...
