Diffusion Of Non-Electrolyte Through Ion Exchange Membranes

When the solute does not carry a charge (non-electrolytes such as urea, glucose and saccharose) it is not electrically coupled with the other fluxes. The flux equation of a non-electrolyte is 

When Dm and yN are constant, the flux of the non-electrolyte across the membrane is (d thickness of the membrane),
