Fouling-resistant biofilter of an anaerobic electrochemical membrane reactor

Up-flow Anaerobic Sludge Blanket Reactor Effluent and Electrochemical Treatments: An Overview

Anaerobic processes present a high potential in most developing countries for municipal wastewater treatment, and thus is a suitable and economical solution. The anaerobic process can serve as a viable alternative, compared to conventional aerobic processes. Within the spectrum of anaerobic sewage treatment technologies, the upflow anaerobic sludge blanket (UASB) reactor offers great promise, e...

Osmotic pressure effect on membrane fouling in a submerged anaerobic membrane bioreactor and its experimental verification.

A laboratory-scale submerged anaerobic membrane bioreactor (SAnMBR) treating sewage was used to investigate the membrane fouling mechanism. Characterization of cake layer formed on membrane surface showed that cake layer was hydrated, rich of extracellular polymeric substances (EPS) and negative charged with the charge density of 0.21-0.46 meq/kg MLSS. Detailed analysis revealed a new membrane ...

Essential metal depletion in an anaerobic reactor.

The effect of the absence of trace elements on the conversion of a mixture of volatile fatty acids by a distillery anaerobic granular sludge was investigated. Two UASB reactors were operated under identical operational conditions except for the influent trace metal concentrations, during 140 days. Experiments were carried out in three periods, where different organic loading rates (OLR) were ap...

Electrochemical Noise Analysis of Anaerobic (Bacterial) Corrosion of Steel

Corrosion of structural steel in an SRB containing environment for as long as 9 months, is studied using the Electrochemical Noise Analysis technique. The results show that the activity of the system, which was very low initially, started to increase after 6 months exposure to the environment. The power spectral density curves of the Electrochemical Potential Noise of the system, using the maxi...
