The term 'membrane bioreactor' expresses a combination of activated sludge and membrane separation processes. The need to processes like sedimentation and disinfection used in common methods is eliminated through MBR systems in a way that membranes are placed into or out of an aeration tank and the vacuumed wastewater created by the suction pump is pulled up from inside the membranes and leaves...

A laboratory-scale membrane bioreactor (MBR) was fed with synthetic wastewater to investigate the possibility of simultaneous removal of organic, nitrogen and phosphorus by intermittent aeration. The MBR consists of two compartments using a microfiltration membrane with 0.2 μm pore size and a surface area of 0.35 m2. Hydraulic retention time was set at 24 hours and solid retention time 25 days....

This work investigated the feasibility of treating micro-polluted surface water for drinking water production with a bio-diatomite dynamic membrane reactor (BDDMR) at lab-scale in continuous-flow mode. Results indicate that the BDDMR was effective in removing COD(Mn), DOC, UV(254), NH(3)-N and trihalomethanes' formation potential (THMFP) at a hydraulic retention time (HRT) of 3.5h due to its hi...

Cationic dye Acridine orange (AO) has wide applications especially in biologicalfields such as analysis of lysosomal and mitochondria content by flow cytometryand so on. In the current work, spectroscopy of acridine orange (AO) dye at bothlow concentrations (mdye/mwater=6.25×10-5, 3.12×10-5) and high concentrations(mdye/mwater=0.002, 0.001) was studied in confined water ...
