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.

A water treatment system includes a water passage, a magnet and a hydroxyl radical generator. Water flows through the water passage. The magnet is adjacent to the water passage and produces a magnetic field in the water passage, The hydroxyl radical generator generates hydroxyl radicals in the water in the water passage. A water treatment method includes the steps of providing a water passage, producing a magnetic field in the water passage, flowing water through the magnetic field and generating, while the water is in the magnetic field, hydroxyl radicals in the water. The water can be recirculated through the water passage a number of times.

A magnetic water treatment system for use in treating water for agricultural and other uses. A magnetic column centered around a perforated shearing tube provides a number of magnets amplified by steel rods to deliver water that has smaller water clusters by treating the water with the application of magnetic fields. Magnetic fields perpendicular to the travel of water and in other directions provide for the efficient treatment of the water.
