Much attention has recently been devoted to the life and behaviour of pharmaceuticals in the water cycle. In this study the behaviour of several pharmaceutical products in different therapeutic categories (analgesics and antiinflammatory drugs, lipid regulators, antibiotics, etc.) was monitored during treatment of wastewater in a laboratoryscale membrane bioreactor (MBR). The results were compa...

The influence of sludge properties in SMEBR and conventional MBR pilot systems on membrane fouling was investigated. Generated data were analyzed using statistical analysis Pearson's product momentum correlation coefficient (r(p)). Analysis showed that TMP had strong direct (r(p)=0.9182) and inverse (r(p)=-0.9205) correlations to mean particle size diameter in MBR and SMEBR, respectively. TMP i...
Treatment of wastewater from a tannery in Greater Ho Chi Minh City (Vietnam) was investigated on a pilot scale. After pre-treatment by the tannery that included batch-coagulation and sedimentation, the wastewater was treated by dissolved air flotation, a membrane bioreactor (MBR) and granular activated carbon (GAC) for polishing the MBR effluent. The average removal efficiency for organic subst...
Aquaporin-based forward osmosis (AQP FO) membranes were applied both in laboratory- and pilot-scale for removing micropollutants from water. The effect of operating parameters (feed flow, draw transmembrane pressure) on the i) rejection micropollutants, ii) water flux, iii) reverse salt iv) recovery AQP FO membrane modules was studied. Among 21 spiked, only four compounds, atenolol, propranolol...
Advanced wastewater treatment using membranes are popular environmental system processes since they allow reuse and recycling. However, fouling is a key limiting factor and so proprietary systems such as Avanti's RPU-185 Flexidisks membrane bioreactor (MBR) use novel rotating membranes to assist in ameliorating it. In earlier research, this rotating process was studied by creating a simulation ...
The presence of pharmaceutical drugs and residues in wastewaters is of concern due the potential health and environmental risks when the wastewater is recycled as an alternative water source. This study investigated the application of an integrated membrane bioreactor with titanium dioxide photocatalytic technology (MBR-TiO2), as a combined treatment barrier to remove Carbamazepine (CBZ) from p...
The operation of an activated sludge process at a paper mill (AIPM) in Hedera, Israel, was often characterized by disturbances. As part of a research and development project, a study on new biological treatment was initiated. The study included the operation of three pilot units: a. anaerobic treatment by upflow anaerobic sludge blanket (UASB); b. aerobic treatment by two pilot units including ...
Several Membrane Bioreactor (MBR) facilities have been constructed with the intent of providing Enhanced Biological Phosphorus Removal (EBPR), and several additional such plants are being designed and constructed. Full-scale plant information is now available for process designers to better understand the unique design and operating issues associated with the incorporation of EBPR designs in MB...
Introduction Wastewater from high-rise buildings such as shopping malls or office buildings play important role in generating large volume of wastewater. These buildings have much higher water consumption rate than typical houses. Also, high loading of organic matters and nutrients in wastewater such as nitrogen and phosphorus can deteriorate water quality of aquatic environment together. Up to...
