The use of reverse osmosis technique in the sector of water treatment and in particular water desalination is well developed and in increase. Meanwhile the problem of high energy consumption by those kinds of techniques pushed end users to ask for ameliorating their energetic efficiency. To respond to that request we are proposing here a modeling approach that uses the theory of electromagnetic waves and that considers the characteristics of the soft material of manufacture of the membrane and its pores. So we can ameliorate the structure and texture of the filtering membrane in the purpose to decrease the energy consumption The salt atoms in their displacements are treated as electromagnetic waves that will undergo a diffraction/polarization through the membranes We have then expressed analytically the reflected / transmitted electric and magnetic fields as function of membrane properties. Evolution of the reflected and transmitted electric field for different angles of incidence (60°, 70° and 90°) were presented. We notice an increase of the reflected electric field intensity.
