Abstract: Mass transfer of a solute of small molecular weight across a hydrophilic membrane is discussed and a simplification of the mass transfer analysis is proposed. It was assumed that the permeability of the boundary layer at the membrane surface depends only on the velocity gradient at that membrane surface. Theoretical results are compared with the values of oxygen output at the dialysis membrane activated with an inorganic catalyst, in the presence of hydrogen peroxide, inside a test chamber of a simple geometry and in the flat plate dialyzer. Test chamber data and the theoretical analysis allow for the prediction of the mass transfer efficiency of the dialyzer.
