CFD modeling of submerged membrane bioreactors (sMBRs): a review

Computational fluid dynamics simulation as a tool for optimizing the hydrodynamic performance of membrane bioreactors

“…Bubbles fare generated from the aeration tube and oat up to the liquid surface, where they gradually disperse to form a feather-like shapes, with the membrane module structure having a signicant effect on gas-liquid mixing efficiency and uid circulation dynamics. 36 Therefore, the height of the arrangement of the membrane modules is an important factor determining gas holdup and uid ow, which led us to investigate the effect of varying the height of the membrane from 250 mm to 650 mm, for an aeration volume of 1.7 m 3 min À1 . The average velocity distributions determined for different membrane heights at the y ¼ 400 mm plane are shown in Fig.…”

Experimental investigation on membrane fouling mitigation by solid-liquid fluidization

“…Novel anti-fouling membrane, and biological-/biochemical-and electrical-based membrane cleaning processes require further implementation in pilot-and industrial-scale, and long-term filtration tests. On the other hand, recent research on the physical-based membrane cleaning processes (e.g., pneumatic-and hydraulic-based, particle fluidization) are focus on the optimization of fouling control with respect to energy usage through hydrodynamic studies, both experimentally [68,69] and using CFD (Computational Fluid Dynamics) simulation [70][71][72][73].…”
