How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
In this study, dextran polysaccharide was used as a hydrophilic non-solvent additive at different molecular weights and concentrations to prepare novel flat sheet PES membranes through non-solvent induced phase separation process. Formation mechanisms of the PES membranes were assessed thermodynamically and kinetically to verify the influence of de...
Dear researchers, Emerging applications of UF membranes in various industries need new green membranes. I am ready to share my ideas about producing new membranes and also checking some of the factors which have important impacts on final membranes but only a few researchers checked them. If you are interested to know more, please do not hesitate...
Can anyone share the Visual Basic or Matlab Code of the membrane distillation process with me?
Thank you so much.
I have a plan for the dimensions of a lab-scale DCMD membrane distillation cell.
Can I fabricate a DCMD membrane distillation cell and use it in Vacuum Membrane Distillation?
If not, what is the difference?
Has any researcher the plan for producing a VMD cell on the lab-scale? Could you please share it with me?
Thank you so much.
What are the best solvent and dissolving temperature for Pebax polymer?
What is the hydrophobicity degree of Pebax polymer?
It is well known that there are different types of nonwoven polyester fabrics.
But which of them is better for the flat sheet hydrophobic PVDF membrane preparation for the MD process?
Could you please tell me the code?
We know that all flat sheet commercial membranes have a substrate that plays the role of a mechanical strength enhancer.
PTFE membranes supported by polyester are also commercial membranes.
On the other hand, PTFE polymer is dissolved in very high temperatures such as 150 C.
How can we have flat sheet PTFE membranes supported by polyester?
Could you please explain?
Grafting is a common method for modifying the polymeric membrane surface to be more anti-fouling.
But, can we use this method for surface modification in pilot and industrial scales membrane fabrication?
Thank you so much for your time.
Membrane separation is playing an increasingly important role in water treatment, wastewater treatment, water reclamation, and desalination applications. Pressure-driven microfiltration (MF), ultrafiltration (UF), and nanofiltration (UF) are used to remove a variety of contaminants from water and wastewater. These membranes have also been widely applied in industrial applications for water recycling and process intensification.
