Investigating the effect of sparger configuration on the hydrodynamics of a full-scale membrane bioreactor using computational fluid dynamics

Abstract

A three-phase computational fluid dynamics (CFD) simulation was carried out in a full-scale membrane bioreactor to investigate the effect of sparger configuration on various hydrodynamic parameters.

Experimental and Numerical Study on the Residence Time Distribution in a Stirred Membrane Reactor

“…The other was for the whole membrane module, such as applying the plug flow model to investigate the plate, , tubular, and spiral wound membrane modules, the single-stage or multi-stage CSTR model to investigate hollow fiber membrane modules, , and some special membrane modules , to investigate the removal and residence of filtrate. Especially, Amini et al studied RTD in a full-size biomembrane reactor and found that the system was closer to plug flow conditions when the flow rate at the inlet was large, the liquid viscosity was low, and the gas inlet was at the bottom inlet. Xie et al found that the dead zone and effective mixing zone in the device were independent of the rotating speed and flow rate in a laminar state but only related to the rotating speed in a turbulent state in a rotating disk filtration module.…”
