Factors Affecting the Performance of Membrane Osmotic Processes for Bioenergy Development

open access: yesEnergies, 2020
Forward osmosis (FO) and pressure-retarded osmosis (PRO) have gained attention recently as potential processes to solve water and energy scarcity problems with advantages over pressure-driven membrane processes. These processes can be designed to produce

Highly Concentrated NaN(SO2F)2/3-Methylsulfolane Electrolyte Solution Showing High Na-Ion Transference Number under Anion-Blocking Conditions

open access: yesElectrochemistry, 2021
The performance of a sodium-ion (Na) battery is significantly influenced by its electrolyte characteristics. In particular, the transport properties of the electrolyte have considerable effects on the discharge rate capability. During discharging of a Na

Concentration Polarization in an Ultrafiltering Capillary

open access: yesBiophysical Journal, 1974
Concentration polarization, the accumulation of retained solute next to an ultrafiltering membrane, elevates osmotic pressure above that which would exist in the absence of polarization. For ultrafiltration in a cylindrical tube, use of the radially averaged solute concentration results in an underestimate of osmotic pressure, yielding an effective ...

Filtration Behaviour and Fouling Mechanisms of Polysaccharides

open access: yesMembranes, 2014
This study investigated filtration behaviors of polysaccharides solutions, both alone and in mixture with proteins, in the short-time constant flux filtration with the focus on factors affecting the transmembrane pressure (TMP) increase rate, the ...

Numerical simulation of colloidal dispersion filtration: description of critical flux and comparison with experimental results [PDF]

open access: yes, 2006
During filtration via membrane processes, colloids accumulate at the porous surface leading to fouling phenomena. In this study, a rigorous simulation of momentum and mass transfer using CFD modelling has been developed to describe such an accumulation ...
