“…However, similar to other membranes, MD membranes are prone to fouling, scaling and membrane wetting (Tijing, Woo et al 2015), which will lead to deteriorated performance. For high salt solutions, in particular when the concentration of salt approaches saturation, scaling becomes the most serious problem (Ji, Curcio et al 2010, Gryta 2011, Edwie and Chung 2013, Chen, Lu et al 2014, Hickenbottom and Cath 2014, Nariyoshi, Pantoja et al 2016, Bouchrit, Boubakri et al 2017, Jiang, Tuo et al 2017, Tang, Iddya et al 2017, Julian, Ye et al 2018, Zou, Dong et al 2018. Crystals attached to the membrane surface alter surface wettability (e.g.…”

Scaling in membrane distillation (MD) is a key issue in desalination of concentrated saline water, where the interface property between the membrane and the feed become critical. In this paper, a new slippery mechanism was explored as an innovative concept to understand the scaling behavior in membrane distillation for a soluble salt, NaCl. The investigation was based on a novel design of a superhydrophobic polyvinylidene fluoride (PVDF) membrane with micro-pillar arrays (MP-PVDF) using a micromolding phase separation (µPS) method. The membrane showed a contact angle of 166.0 ± 2.3° and the sliding angle of 15.8 ± 3.3°. After CF4 plasma treatment, the resultant membrane (CF4-MP-PVDF) showed a reduced sliding angle of 3.0 o. In direct contact membrane distillation (DCMD), the CF4-MP-PVDF membrane illustrated excellent anti-scaling in concentrating saturated NaCl feed. Characterization of the used membranes showed that scaling due to NaCl crystals and possible membrane wetting occurred on the control PVDF and MP-PVDF membranes, but not on the CF4-MP-PVDF membrane. To understand this phenomenon, a "slippery" theory was introduced and correlated the sliding angle to the slippery surface of CF4-MP-PVDF and its anti-scaling property. This work provides a well-defined physical and theoretical platform for investigating scaling problems in membrane distillation and beyond.

“…Osmotic pressure and concentration polarization are also limited, while affecting severely a more traditional seawater reverse osmosis (SWRO). 20 Precisely, in MD and MCr devices, a hydrophobic membrane works as a physical interface between two phases, preventing the dispersion of one phase within another. 21 The two phases in the form of liquid-liquid or liquid-gas come in contact at the entrance of the membrane pores.…”

“…The literature has reported that membrane crystallization successfully produced drug‐coating particles and other macromolecular substances, when using membrane distillation or vacuum to provide the driving force . Using a membrane to control the antisolvent distribution was promising to achieve a homogeneous mass transfer rate and improved micromixing conditions . However, the stability of the membrane module in continuous application has not been well studied.…”

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
