In at least one illustrative embodiment, an electromagnetic filter may include a transfer pipe and multiple electromagnetic filter elements positioned in an interior volume of the pipe. Each electromagnetic filter element includes a support comb, a solenoid coupled to the support comb, and multiple magnetic members arranged in a planar array positioned within an opening of the support comb. Each magnetic member may rotate about an end that is coupled to the support comb. The magnetic members may be magnetostrictive sensors and may include a biorecognition element to bind with a target microorganism. A method for fluid filtration includes coupling the electromagnetic filter between a fluid source and a fluid destination, energizing the solenoids of each electromagnetic filter elements, and flowing a fluid media through the transfer pipe of the electromagnetic filter. The fluid media may be liquid food such as fruit juice. Other embodiments are described and claimed.

The present invention is related to a high aspect ratio column thickener and a process thereof useful for dewatering of iron ore tailings. The column thickener has been developed with multiple feed inlet points and an auxiliary inlet point for water to clear the jam of high concentration slurry, if required. The column also consists of a conical portion at the bottom. Magnetic field has been applied using induced magnetic coil just above the conical portion of column thickener. Iron ore tailings slurry is fed into the column thickener and particles are allowed to settle in axial direction with and without the application of magnetic field.
