In this paper, a new method for the improvement of the performance of magnetic filters for the removal of disperses mixtures with magnetic characteristics from industrial liquids and gases is investigated. In order to accelerate the reduction of the concentration of dispersed mixture, it is suggested that the intensity of the external magnetic field throughout the magnetic filter should be adjusted regionally. To achieve this goal, an intermediate control circuit with PWM (Pulse Width Modulation) driver capable of driving the external magnetic fields of magnetic filter regionally based on three regions is designed. The dsPIC30F2010 Digital Signal Controller (DSC; Microchip (R)) is used in the controller circuit. The experimental results show that the concentration of dispersed magnetic mixture contained in the aqueous suspension passed from magnetic filter is reduced more efficiently. It is claimed that due to the adjustment of the external magnetic field intensity applied to the magnetic filters throughout the magnetic filter, the filter performance is increased, the electrical energy consumption is reduced, and the optimum design of magnetic filters is achieved.
