Integrating nanotechnology and membrane technology has resulted in the development of adsorptive nanocomposite membranes with exceptional properties for various applications, including water reclamation. The application wastewater treatment is a promising that combines advantages adsorption filtration techniques. Literature reviews reported were successfully developed efficiently removed emergi...
Electrospun nanofber membranes (ENMs) are new generation of membranes with many favorable properties such as high flux and low pressure drop. Although electrospinning has been known for more than a century, its applications in fltration and separation processes are relatively new. Electrospinning has provided the means to produce ultrathin fbers – as thin as a few nanome...
A method for immobilization of β-galactosidase from Kluyveromyces lactis on an adsorptive membrane for the continuous synthesis of galacto-oligosaccharides from lactose was carried out. The immobilization was performed at 4, 10, 15 and 40°C. Two strongly basic anion exchange membranes with tradename MustangQ and SartobindQ were investigated. In static experiments, the highest enzyme activity wa...
Excessive nutrient contents in water bodies renders eutrophication and causes undesired structural changes to the environment. One of the most straightforward strategies to address eutrophication issue is through the removal of nutrients such as phosphate ions from the water sources. A combination of membrane fltration and adsorption process is an attractive alternative...
Dialytic clearance of p-cresyl sulfate (pCS) and other protein-bound toxins is limited by diffusive convective therapies, only a few studies have examined how to improve their removal adsorptive membranes. This study tested the hypothesis that high-flux polymethylmethacrylate (PMMA) dialysis membranes with capacity increase pCS compared polysulfone membranes, in postdilution on-line hemodiafilt...
The capacity for secondary effluent filtration of hollow fiber polypropylene membranes grafted with several zwitterionic molecules and multi-walled carbon nanotubes was evaluated. In particular, all the modifications result in significant improvement of filtration performances. The anti-fouling properties of the membrane had been increased without damaging the membrane as observed from FTIR, TG...
Membranes are finding wide applications in various fields spanning biological, water, and energy areas. Synthesis of membranes to provide tunable flux, metal sorption, and catalysis has been done through pore functionalization of microfiltration (MF) type membranes with responsive behavior. This methodology provides an opportunity to improve synthetic membrane performance via polymer fabricatio...
