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 ...
Leaching of PVP from PVDF/PVP blend membranes: Impacts on membrane structure and fouling in membrane bioreactors
(Springer US, 2016-05)
Polyvinylidene fluoride (PVDF) membranes are widely used in membrane industry, especially for membrane bioreactors (MBRs). Many PVDF membranes contain residual polyvinyl pyrrolidone (PVP) that acts as a pore-forming additive. ...
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 ...
Brine management in desalination industry: From waste to resources generation
(Elsevier, 2019-12)
Desalination brine has high salinity and contains various chemical contaminants and its disposal causes a major concern for desalination around the world. Environmentally friendly and economically feasible methods are ...
Photocatalytic hollow fiber membranes for the degradation of pharmaceutical compounds in wastewater
(Elsevier, 2017-10)
In this research, the degradation by heterogeneous photocatalysis of organic pharmaceutical waste compounds using TiO2 nanoparticles immobilized on polymeric commercial hollow fiber (HF) ultrafiltration membranes was ...
Fabrication of blend polyvinylidene fluoride/chitosan membranes for enhanced flux and fouling resistance
(Elsevier, 2018-01)
The fabrication of polyvinylidene fluoride (PVDF) membranes was studied using chitosan as a hydrophilic additive for flux enhancement and stability. Chitosan (CS) was blended with PVDF at 0.5, 1.0, 1.5, 2.0 and 2.5% (w/w) ...
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 ...
Thin film deposition techniques for polymeric membranes–A review
(Elsevier, 2020-09)
Thin film deposition (TFD) allows for precise tuning of the chemical and physical properties of a membrane to improve performance, including the selectivity, flux, chemical resistance, and antifouling and antimicrobial ...
Assessment and rationalization of water quality monitoring network: a multivariate statistical approach to the Kabbini River (India)
(Springer Berlin Heidelberg, 2014-09)
The establishment of an efficient surface water quality monitoring (WQM) network is a critical component in the assessment, restoration and protection of river water quality. A periodic evaluation of monitoring network is ...
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 ...
