    • In this approximation, it is assumed that the flux of a solute relative to the center of mass is proportional to the gradient of electrochemical potential of this solute alone. Generally, for example, due to the solution nonideality, there are some contributions of gradients of electrochemical potentials of other solutes

    • The electrode potential is controlled by the salt concentrations in the feed and the permeate compartments. After pressure switch-off, the permeate concentration ultimately changes due to the salt diffusion through the membrane. However, in our setup, this takes quite a long time (at least 1 h) primarily due to the presence of relatively thick porous support beneath the membrane. Our measurements were essentially shorter up to 100 s

    • The fact that the fluctuations decayed more rapidly in the more concentrated solution (lower electrical resistance) can be an indication of their appearance due to the presence of some parasitic inductivities and capacities in our system
