Publikováno v: Journal of Membrane Science. 179:163-174

In order to account for the role of electrostatic interactions during ultrafiltration of a charged protein, electrokinetic characterisation of the protein-membrane-electrolyte system was performed. The zeta-potential (ψz) of the protein-fouled (memb

Ultrafiltration and reverse osmosis of small non-charged molecules: a comparison study of rejection in a stirred and an unstirred batch cell

Autor: B. Bariou, F. Beline, Béatrice Balannec, S. Nicolas

Publikováno v: Journal of Membrane Science. 164:141-155

This study deals with the estimation of rejection coefficient for small non-charged molecules in an aqueous solution, with reverse osmosis and ultrafiltration membranes in a stirred and an unstirred cell. In a stirred cell with high stirring velocity

Experimental study and modelization of reverse osmosis with salt solutes in an unstirred batch cell

Autor: B. Bariou, Béatrice Balannec, S. Nicolas

Publikováno v: Desalination. 122:43-51

The study deals with reverse osmosis of salt solutes in an unstirred batch cell at a rejection coefficient very close to 1. The experiments were performed in a stainless steel batch cell specially manufactured in order to lower the dead volume under

The study of the swelling of an ultrafiltration membrane under the influence of solvents by thermoporometry and measurement of permeability

Autor: Nabil Mameri, J.F. Quinson, L. Guihard, B. Bariou

Publikováno v: Journal of Membrane Science. 58:191-200

The pore radius of organic symmetrical ultrafiltration membranes soaked in various solvents was measured by means of thermoporometry. It can be shown that pores radius modification induced by the solvents take into account the α parameter used by N'

Effects of diffusion and osmosis on flux decline during ultrafiltration with total rejection in an unstirred batch cell

Autor: F.E. Danes, B. Bariou, S. Poyen

Publikováno v: Journal of Membrane Science. 50:177-187

Parameters of the flux decline relationships of ultrafiltration with total rejection in an unstirred batch cell of infinite extent are expressed as functions of operating conditions (initial concentration c o , applied pressure difference P , membran

Unstirred dead-end ultrafiltration : a method to determine diffusion coefficient or osmotic pressure for non-charged macromolecular solutions

Autor: B. Bariou, S. Nicolas, I. Boulanouar

Journal of Membrane Science, 1995, 103, pp.19-30
Journal of Membrane Science, Elsevier, 1995, 103, pp.19-30

Concentration polarization phenomenon in ultrafiltration or reverse osmosis processes is governed by a non linear convective-diffusion equation. General unsteady state equations associated with the osmotic theory relationship are solved numerically.

Textural Characterization of Ultrafiltration Membranes by Thermoporometry and Liquid Flow Measurement

Autor: B. Bariou, J.F. Quinson, N. Nameri

Summary The porous texture and the permeability of an organic and symmetrical ultrafiltration membrane, aged in different solvents, are determined by water thermoporometry and water flow measurement, respectively. The permeability variation observed,
