Herein, a novel hollow fiber membrane‐assisted antisolvent crystallization (MAAC) was proposed to enhance the mass transfer control over the antisolvent crystallization. A polyethersulfone membrane module was introduced as the key device for antisolvent transfer and solution mixing. An antisolvent liquid film layer was formed on the membrane surface and mixed with the solution. The liquid film also prevented the membrane from directly contacting with crystallization solution. By controlling both the shell side flow velocity and the antisolvent transfer, the antisolvent permeation rate achieved sensitive, stable, and accurate control during long‐term and repeated utilization. The interfacial mass transfer rate of MAAC was 0.66 mg cm−2 s−1, which was only 1/50 that of conventional droplet antisolvent crystallization. MAAC also provided crystal products with better morphologies and narrower size distributions than the conventional process. The stable performances of MAAC in terms of its accurate antisolvent mass transfer and antifouling capabilities were also highlighted. © 2018 American Institute of Chemical Engineers AIChE J, 65: 734–744, 2019

“…Over the past decade, membrane crystallization (MCr), an innovative hybrid separation technology combining membrane technology with crystallization, has rapidly developed . With the intrinsic advantages of membrane technology and an improved energy utilization efficiency, MCr can simultaneously produce the desired crystal product and ultrapure solvent with relatively low energy input . The hollow fiber membrane module utilized in MCr provides a plentiful and uniform contact interface for the mass transfer of the crystallization solution, which facilitates the precise control of the supersaturation degree and micromixing condition.…”

Accurate crystallization control is an essential aspect for chemical engineering and separation processes. Herein, we demonstrated the novelty of membrane crystallization (MCr) on the interfacial based‐crystal particle autoselection aimed for nucleation regulation and process control. With the proposed model based on a van der Waals‐friction‐hydrodynamic force field and classical nucleation theory, the motion mechanisms of heterogeneously induced nucleation were illustrated. The defined particle detachment criterion K revealed the control mechanism of the crystal particle motion behavior: temporary adherence, detachment, and perpetual adherence (scaling) at the membrane interface. For the first time, the function region of MCr (nucleation detection, scaling control, and crystallization regulation) was systematically illustrated and validated with the directly observed laboratory demonstration. These findings also demonstrate the potential applications of the uniform size distribution, morphology modified particle manufacture, and in situ nucleation detection. © 2018 American Institute of Chemical Engineers AIChE J, 65: 723–733, 2019

“…The process can simultaneously produce freshwater and crystals of the dissolved salts, thus approaching zero liquid discharge without any additional post-treatment [10]. The technical potential of MD for various applications, such as desalination, environmental/waste clean-up, water reuse, and in the food and medical industry has been well-demonstrated in the literature [11][12][13].MCr has been particularly investigated for the simultaneous recovery of salts and freshwater from various types of brine solution [14][15][16]. Ji et al [17] applied MCr to recover high-purity NaCl from the reverse osmosis concentrate of real seawater.…”

The treatment of wastewater containing various metal ions is a challenging issue in the anodizing industry. The current study investigates the application of membrane distillation/crystallization (MD/MCr) for the simultaneous recovery of freshwater and sodium sulfate from wastewater originating from a Danish anodizing industry. MD/MCr experiments were performed on supernatant from wastewater obtained after centrifugation. The effect of various feed temperatures and cross-flow velocities on flux and crystal characteristics was investigated. The crystal growth in the feed tank was monitored through the use of an online PaticleView microscope. The crystals’ morphology and form were determined by using scanning electron microscope (SEM) and X-ray powder diffraction (XRD), respectively, while inductively coupled plasma (ICP) was applied to determine the purity of the obtained crystals. The weight and dimensions of the MD/MCr unit that were required to treat the specific amount of wastewater were evaluated as a function of the feed inlet temperature. It was demonstrated that the application of MCr allows extracting high-purity sodium sulfate crystals and more than 80% freshwater from the wastewater.
