Hydrodynamics of an electrolyte solution transport through a reverse osmosis membrane is considered for processes caused by the gradients of particle concentration, temperature, difference of external and osmotic pressures as well as dielectric properties of initial solution, membrane, filtrate. By means of Zubarev nonequilibrium statistical operator generalized equations of hydrodynamics for ions and molecules in the system initial solution - membrane - filtrate are obtained taking into account dielectric properties of a solution. Equations of hydrodynamics are analysed for three phases with consideration of features related to rotational movement and dielectric relaxation of polar solvent molecules.
