Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. The membrane is an absolute barrier to suspended matter and microorganisms and it offers the possibility of operating the system at high mixed liquor suspended solids (MLSS) concentration. Th...

PURPOSE The purpose of this study was to evaluate the correlation between laser speckle flowgraphy measurements of mean blur rate (MBR) and hydrogen gas clearance measurements of capillary blood flow (CBF) in the optic nerve head (ONH) of albino and pigmented rabbits, with or without chronic ischemia-induced ONH atrophy. METHODS The ONH MBR and ONH CBF were measured at baseline, 30 and 60 min...

PURPOSE To describe the utility of school-wide use of mission-based reporting (MBR) for medical school deans and department chairs. METHOD All faculty members in the University of California, Davis, School of Medicine reported their clinical, creative, teaching, and service activities for 2000-2001 to the MBR system. The authors report on school-wide and department MBR profiles, and profiles ...

Human adenoviruses (HAdVs) in wastewater samples taken from four different treatment stages of a full-scale municipal wastewater treatment plant (i.e., incoming raw sewage, primary sedimentation effluent, membrane bioreactor (MBR) influent, and MBR effluent) were quantified by real-time PCR assays to further estimate removal efficiency of the HAdVs. Based on hexon gene sequence comparisons, HAd...

This study demonstrated the importance, process, activation and applications of Membrane in bioreactor to treat the waste water. Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. Operating as an MBR allows conventional activated sludge plant...

This study focuses on the application of combining membrane bioreactor (MBR) treatment with reverse osmosis (RO) or nanofiltration (NF) membrane treatment for removal of pharmaceuticals and personal care products (PPCPs) in municipal wastewater. Twenty-seven PPCPs were measured in real influent with lowest average concentration being trimethoprim (7.12 ng/L) and the highest being caffeine (18.4...

Introduction MBRs (membrane bioreactors) are a recent innovation of the activated sludge process, which eliminates many constraints associated with the traditional gravity settling. Nevertheless, it suffer membrane fouling. The colloidal and macromolecular fraction of MBR sludge has been reported as the main foulant of MBR systems. SMP can be classified into BAP (biomass associated products) an...

PURPOSE To report retinal blood flow levels measured by Laser speckle flowgraphy in three patients after they received an intravitreal bevacizumab injection (IVB) for macular edema secondary to central retinal vein occlusion (CRVO). METHODS Three patients (3 eyes) being treated with IVB (1.25 mg/0.05 mL) for secondary macular edema of CRVO were examined. Laser speckle flowgraphy analyses of t...

The aim of this study was to assess the potential removal efficacy of enteric viruses in a fullscale membrane bioreactor (MBR) wastewater reuse system, using a range of indigenous and ‘spiked’ bacteriophages (phages) of known size and morphology. Samples were taken each week for three months from nine locations at each treatment stage of the water recycling plant (WRP) and tested for a range of...
