  • Publication number: 20230149946
    Abstract: 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.

  • Publication number: 20210086113
    Abstract: In at least one illustrative embodiment, an electromagnetic filter may include a pipe and a magnetic field generator such as an array of permanent magnets. The magnetic field generator generates a magnetic field through a filter section of the pipe. Multiple filter elements are positioned within the filter section of the pipe. The filter elements include a magnetic material and a biorecognition element to bind with a microorganism. The biorecognition element may be a bacteriophage that is genetically engineered to bind with the microorganism. The magnetic field forces the filter elements to positions within the filter section of the pipe. A fluid media may be flowed from an inlet of the pipe to an outlet of the pipe, through the filter section. The fluid media may be a liquid food such as fruit juice. Other embodiments are described and claimed.
