Summary: Investigated the overall dependency of magnetic filtration technology process for liquid substances with identify of key values: magnetic susceptibility of particles, magnetic power factor of capturing particles zones by filling, velocity profile of the liquid in the pores of the filling. As a result, the overall refined equation of magnetic filtration of purification process, in which as the impact parameter magnetic forces uses the value of the magnetic field fillings instead of the external magnetic field.

Key words: magnetic field, deposition, magnetic field, induction magnetic field.
