Accelerated azo dye removal by biocathode formation in single-chamber biocatalyzed electrolysis systems.

Biocatalyzed electrolysis systems (BES) have been the topic of a great deal of research. However, the biocathodes formed in single-chamber BES without extra inocula have not previously been researched. Along with the formation of biocathodes, the polarization current increased to 1.76 mA from 0.35 mA of abio-cathodes at -1.2 V (vs. SCE). Electrochemical impedance spectroscopy (EIS) results also...

Biological Treatment of a Synthetic Dye Water and an Industrial Textile Wastewater Containing Azo Dye Compounds

In this research, the ability of anaerobic and aerobic biological sludges to reduce and stabilize azo dye compounds was studied. Synthetic dye solutions and an industrial textile wastewater were both treated using anaerobic and aerobic biomass, separately and in sequential step-treatment processes. The primary objective was to reduce the wastewater color to an intensity that complies with the V...

Efficient treatment of baker’s yeast wastewater using aerobic membrane bioreactor

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...

Feasibility of hybrid bioreactor in the treatment of wastewater containing slowly biodegradable substances

Slowly biodegradable substances and recalcitrant pose a serious threat to the environment owing to their bio-resistant nature. With the increase in industrial activities, more and more quantity of these substances is being discharged through wastewater. The biodegradability potential of such substances can be anticipated from low BOD/COD ratio. Traditionally, the wastewater containing recalcitr...

Hybrid treatment systems for dye wastewater

Virtually all the known physico-chemical and biological techniques have been explored for treatment of extremely recalcitrant dye wastewater; none, however, has emerged as a panacea. A single universally applicable end-of-pipe solution appears to be unrealistic, and combination of appropriate techniques is deemed imperative to devise technically and economically feasible options. An in-depth ev...
