Mass transfer modelling of hollow fiber membrane contactor for apple juice concentration using osmotic membrane distillation

, 2020
The present research study is based on theoretical and experimental investigation of hydrophobic porous hollow fiber membrane contactor (HFMC) module. The mass transfer diffusional model was developed for osmotic membrane distillation (OMD) and applied ...

Osmotic distillation through porous hydrophobic membranes

Journal of Membrane Science, 1993
Abstract Osmotic distillation through porous hydrophobic membranes has been studied theoretically and experimentally. In particular the influence of the unstirred diffusion boundary layer has been determined. A model has been develop which describes the contributions of solution concentration and stirring rate.

Acoustic field-assisted osmotic membrane distillation

Desalination, 2002
Abstract Osmotic membrane distillation (OMD) is a novel membrane process that facilitates the concentration of aqueous solutions under mild operating conditions. The main drawback of OMD, like any other membrane process, is relatively low flux. In the present work acoustic field has been applied for the enhancement of transmembrane flux.

Alkaline water electrolysis‐driven osmotic membrane distillation for concentrating organic aqueous solution

AIChE Journal
Aqueous organic electrosynthesis produces valuable chemicals sustainably but yields dilute solutions, making separation energy‐intensive. While osmotic membrane distillation (OMD) concentrates solutions, it requires energy to regenerate its draw ...

Coupled Phenomena Membrane Distillation and Osmotic Distillation through a Porous Hydrophobic Membrane

Separation Science and Technology, 1995
Abstract Water transport in the vapor phase through a porous hydrophobic membrane has been studied in different experimental situations. Pure water and/or different aqueous solutions of sodium chloride, ranging from 0.5 to 5 mol/L, were employed on both sides of the membrane.

Membrane osmotic distillation and its mathematical simulation

Desalination, 2001
Abstract A membrane distillation process with brine circulated in the cold side was developed. This process combines the ordinary membrane distillation (MD) with the osmotic distillation (OD), and is therefore called membrane osmotic distillation (MOD). Comparisons of MOD with MD and OD were carried out.
