“…The explanation for spray drying decreasing the carbon dioxide capture capacity of the WPI powders may be due to the protein denaturation on the droplet surfaces, which are at the gas-liquid interfaces [63]. The WPI is often used as a drying aid because of its amphoteric properties [64].…”

“…24 The initial rate of adsorption is often diffusion-rate limited, with smaller proteins diffusing more rapidly than larger molecules. 24,25 As molecules accumulate at the interface, diffusion is no longer rate limiting. Instead, the adsorbing molecule must often diffuse against a barrier, often electrical, 15,24,26,27 as well as open a space of sufficient size to allow initial attachment at the interface.…”

“…submerged membrane bioreactors ), there are some limitations in the applications of this coupled system. For instance, in most bio-separation processes using UF/MF hollow fiber modules [74], the fragmentation of protein or micro-organisms [81][82][83] could occur and aggregation could easily happen due to the high shear rate when bubbles burst. Therefore, bubble-flow induced bio-separation process can only perform well under relatively low air sparging rates.…”

Membrane-based separation processes have found numerous applications in various industries over the past decades. However, higher energy consumption, lower productivity and shorter membrane lifespan due to polarization and membrane fouling continue to present severe technical challenges to membrane-based separation. Improved membrane module design and novel hydrodynamics offer strategies to address these challenges.This review focuses on hollow fiber membrane modules which are well-suited to membrane contactor separation processes. Attempts to improve membrane module design should begin with a better understanding of the mass transfer in the hollow fiber module, therefore this review provides a summary of prior studies on the mass transfer models related to both the shell-side and tube-side fluid dynamics. Based on the mass transfer analysis, two types of technique to enhance hollow fiber membrane module performance are discussed: (1) passive enhancement techniques that involve the design and fabrication of effective modules with optimized flow geometry; or (2) active enhancement techniques that uses external energy to induce a high shear regime to suppress the undesirable fouling and concentration polarization phenomena. This review covers the progress over the past five years on the most commonly proposed techniques such as bubbling, vibrations and ultrasound.Both enhancement modes have their advantages and drawbacks. Generally, the passive enhancement techniques offer modest improvement of the system performance, while the active techniques, including bubbling, vibrating and ultrasound, are capable of providing as high as 315 times enhancement of the permeation flux. Fundamentally, the objectives of module design should include the minimization of the cost per amount of mass transferred (energy consumption 3 and module production cost) and the maximization of the system performance through optimizing the flow geometry and operating conditions of the module, scale-up potential and expansion of niche applications. It is expected that this review can provide inspiration for novel module development.
