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...

Mesangial cells are smooth muscle-like pericytes that abut and surround the filtration capillaries within the glomerulus. Studies of the fine ultrastructure of the glomerulus show that the mesangial cell and the capillary basement membrane form a biomechanical unit capable of regulating filtration surface area as well as intraglomerular blood volume. Structural and functional studies suggest th...

This study focused on the effect of powder activated carbon (PAC) adsorption on microfiltration (MF) membrane performance. The results showed that PAC pretreatment offered high organic matter removal rates for both dissolved organic carbon (DOC) and ultraviolet absorbance at 254 nm (UV254) during 10-200 mg/L PAC dosage. The removal efficiencies of organic matter by MF membrane filtration decrea...

Background and Objectives: Pomegranate juice is prone to turbidity, which makes it hard to preserve and concentrate. Microfiltration is one of the membrane processes that can be used to reduce its turbidity, but, it is prone to membrane fouling. Pretreatment is considered the most effective way to reduce membrane fouling. Materials and Methods: This study simulated the effect of centrifugation...
