We have formulated the problem that occurs when processing vegetable oils at the stage of their filtering. The method and technical means of its solution are proposed with the use of electroflotation with the prior hydration of phosphatides. To prove the efficiency of the proposed method, a mathematical model was developed, which is based on the dynamics of dielectric particles in the electric field and the solution of the corresponding differential equation of their motion. On the basis of the numerical solution of the differential equation of motion of particles, dependences of the velocity of precipitation of water droplets on the electrodes of an electroflotation from the distance to the electrode and the voltage on the electrodes were obtained. This made it possible to determine the time of water removal, along with oil impurities, and the structural parameters of the system of electrodes, as well as the efficiency of the electroflotator. The adequacy of the theoretical model was confirmed by experimental studies. The difference between the experimental and theoretical data does not exceed 7%.
