Abstract

A method and apparatus in which water is magnetically treated to kill microorganisms such as bacteria colonies in water systems, thereby reducing the requirements and cost of watersystem maintenance and the quantity of toxic chemical treatments released to the environment. The method includes removing a volume of water from a bacterially or microorganism contaminated environment, magnetically treating the water, then returning the treated water back to the environment. The apparatus includes a permanent magnet of alternating polarity to form a magnetic field through which the water is treated and passed.

Claims

1. A method for treating water to kill microorganisms, said method comprising:

providing a first volume of water containing microorganisms;

treating at least a portion of said volume of water by passing said portion through a plurality of magnetic fields of alternating polarity formed by a magnet surrounded by a magnetic casing to maximize the magnetic field therein, said volume of water passing through said casing; and

mixing said treated portion back into said first volume thereby killing said microorganisms.

2. A method for treating water to kill bacteria, said method comprising:

providing a first volume of water containing bacteria;

treating at least a portion of said volume of water by passing said portion through a plurality of magnetic fields of alternating polarity formed by a magnet disposed in a magnetic casing, said magnet having poles disposed parallel with said volume of water passing thereby, said volume of water passing through said magnetic casing; and

mixing said treated portion back into said first volume thereby killing said bacteria.

3. The method of claim 2 in which said mixing said treated water with said first volume is accomplished with a pump.

4. The method of claim 2 in which said first portion of water comprises waste water, said method killing Escherichia Coli present in said first portion of water.

5. A method for treating water to kill Escherichia Coli bacteria, said method comprising:

providing a first volume of water containing Escherichia coli bacteria;

treating at least a portion of said volume of water by passing said portion through a plurality of magnetic fields of alternating polarity formed by a magnet surrounded by a magnetic casing to maximize the magnetic field therein, said volume of water passing through said casing said magnet having poles disposed parallel with said volume of water passing thereby; and

mixing said treated portion back into said first volume thereby killing said Escherichia coli bacteria.

6. A method for treating a volume of water to kill bacteria within the water, said method comprising:

treating a portion of said volume of water by passing said portion through a plurality of magnetic fields of alternating polarity formed by a magnet surrounded by a magnetic casing, said volume of water passing through said casing; and

mixing said treated portion back into said first volume whereby bacteria within the water are killed.

7. The method of claim 6 in which said treatment includes passing said portion through a plurality of magnetic fields having pairs of like poles adjacent each other.
