3D printed spacers for organic fouling mitigation in membrane distillation
(Elsevier, 2019-08)3D printing offers the flexibility to achieve favorable spacer geometrical modification. The role of 3D printed spacers for organic fouling mitigation in direct contact membrane distillation (DCMD) is evaluated. Compared ... -
Antiscaling 3D printed feed spacers via facile nanoparticle coating for membrane distillation
(Elsevier, 2021-02)Surface modification of feed spacers rather than membranes may hold more merit as an antiscaling strategy in membrane distillation (MD), as it avoids compromising the functionality of MD membrane. In this work, an antiscaling ... -
Comparative assessment of the effects of 3D printed feed spacers on process performance in MD systems
(Elsevier, 2021-05)In this study, process enhancements achieved by the use of 3D printed feed spacers based on triply periodic minimal surfaces (TPMS) were comparatively assessed using the two most common membrane distillation (MD) configurations: ... -
Exploiting the interplay between liquid-liquid demixing and crystallization of the PVDF membrane for membrane distillation
(Hindawi, 2018)Membrane distillation (MD) purifies water by transporting its vapor through a hydrophobic membrane. An ideal MD membrane poses high water flux and high fouling, scaling, and wetting resistances. In this study, we develop ... -
Membrane distillation research & implementation: Lessons from the past five decades
(Elsevier, 2017-12)Research on membrane distillation (MD) experienced a slow growth from the 1970s through 90s but has gained revived interest recently. Despite recent developments, MD still has to overcome several hurdles to pave its path ... -

PVDF/magnetite blend membranes for enhanced flux and salt rejection in membrane distillation
(Elsevier, 2018-06)This study reports on the enhancement of direct contact membrane distillation (DCMD) performance by incorporating magnetite nanoparticles (NP) in polyvinylidene fluoride (PVDF) membranes to render the membrane bulk hydrophilic ... -
Reversing membrane wetting in membrane distillation: comparing dryout to backwashing with pressurized air
(Royal Society of Chemistry, 2017)The critical failure mode for membrane distillation (MD) desalination is wetting through the pores of the hydrophobic membrane, which allows the saline solution to leak through and contaminate the permeate. The standard ... -
Shrinkage, defect and membrane distillation performance of composite PVDF membranes
(Elsevier, 2015-11)This study addresses the importance of non-woven support (NWS) during the preparation of polyvinylidene fluoride (PVDF) membranes for membrane distillation (MD). Five different NWSs were investigated as substrate materials ... -
Understanding wetting phenomena in membrane distillation and how operational parameters can affect it
(Elsevier, 2016-10)Direct contact membrane distillation experiments were carried out under this work to study the influence of operational variables on membrane wetting. In the first part of this work, experiments were designed according to ...
