The effect of flower-like tatania towards characteristics and performance of polysulfone mixed matrix membrane
For ages, the polymeric membrane such as PSf is widely used in liquid separation for various application as the polymer itself offer versatile and attractive properties. However, due to strong hydrophobic nature of PSf property that create serious fouling problem to most of the separation process, …

Implementing Electrochemical Impedance Spectroscopy for the In Situ Analysis Of Conducting-Membrane Fouling
… and industrial productivity continue to rise, membrane filtration technologies provide a compelling solution for the production of clean water. Membranes are versatile, energy-efficient, and highly effective, yet they suffer from the indomitable problem of fouling. Abundant research has been …

Development of new membranes for desalination pre-treatment
The use of membranes in water filtration is on the rise as they are reliable and filter wide variety of pollutants and fouling agents. On the other hand, fouling of the membrane and initial cost of the setup and the membrane itself are the areas which need major improvement. In this thesis, testing …

Study on Structure and Vacuum Membrane Distillation Performance of PVDF Composite Membranes: Influence of Molecular Weight and Blending
In this study, membranes were made from three polyvinylidene fluoride (PVDF) polymers individually and the blend systems of high (H) and low (L) molecular weight PVDF by phase inversion process. After investigating membrane casting solutions’ viscous and thermodynamic properties, the membranes so …
